Abstract
PURPOSE Prostate-specific membrane antigen (PSMA) is increasingly considered as a molecular target to achieve precision surgery for prostate cancer. A Delphi consensus was conducted to explore expert views in this emerging field and to identify knowledge and evidence gaps as well as unmet research needs that may help change practice and improve oncological outcomes for patients. METHODS One hundred and five statements (scored by a 9-point Likert scale) were distributed through SurveyMonkey®. Following evaluation, a consecutive second round was performed to evaluate consensus (16 statements; 89% response rate). Consensus was defined using the disagreement index, assessed by the research and development project/University of California, Los Angeles appropriateness method. RESULTS Eighty-six panel participants (72.1% clinician, 8.1% industry, 15.1% scientists, and 4.7% other) participated, most with a urological background (57.0%), followed by nuclear medicine (22.1%). Consensus was obtained on the following: (1) The diagnostic PSMA-ligand PET/CT should ideally be taken < 1 month before surgery, 1-3 months is acceptable; (2) a 16-20-h interval between injection of the tracer and surgery seems to be preferred; (3) PSMA targeting is most valuable for identification of nodal metastases; (4) gamma, fluorescence, and hybrid imaging are the preferred guidance technologies; and (5) randomized controlled clinical trials are required to define oncological value. Regarding surgical margin assessment, the view on the value of PSMA-targeted surgery was neutral or inconclusive. A high rate of "cannot answer" responses indicates further study is necessary to address knowledge gaps (e.g., Cerenkov or beta-emissions). CONCLUSIONS This Delphi consensus provides guidance for clinicians and researchers that implement or develop PSMA-targeted surgery technologies. Ultimately, however, the consensus should be backed by randomized clinical trial data before it may be implemented within the guidelines.

Abstract
INTRODUCTION The introduction of novel surgical techniques and procedures remains poorly regulated and standardised. Although the learning curve associated with invasive procedures is a critical part of innovation, it is currently inconsistently defined, measured and reported. This study aims to develop a core data set that can be applied in all studies describing or measuring the learning curve in novel invasive procedures. METHODS A core data set will be developed using methods adapted from the Core Outcome Measures in Effectiveness Trials initiative. The study will involve three phases: (1) Identification of a comprehensive list of data items through (a) an umbrella review of existing systematic reviews on the learning curve in surgery and (b) qualitative interviews with key stakeholders. (2) Key stakeholders (eg, clinical innovators, clinicians, patients, methodologists, statisticians, journal editors and governance representatives) will complete a Delphi survey to score the importance of each data item, generating a shortened list. (3) Consensus meeting(s) with stakeholders to discuss and agree on the final core data set. ETHICS AND DISSEMINATION The study is approved by an Institutional Ethics Committee at the University of Bristol (ref: 111362). Participants will complete written informed consent to participate. Dissemination strategies include scientific meeting presentations, peer-reviewed journal publications, patient engagement events, use of social media platforms, workshops and other events.

Treatment options for patients with pilonidal sinus disease: PITSTOP, a mixed-methods evaluation. Health Technol Assess 2024; 28:1-113. [PMID: 39045854 DOI: 10.3310/kfdq2017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 07/25/2024] Open
Abstract
Background There is no consensus on optimal management of pilonidal disease. Surgical practice is varied, and existing literature is mainly single-centre cohort studies of varied disease severity, interventions and outcome assessments. Objectives A prospective cohort study to determine: • disease severity and intervention relationship • most valued outcomes and treatment preference by patients • recommendations for policy and future research. Design Observational cohort study with nested mixed-methods case study. Discrete choice experiment. Clinician survey. Three-stage Delphi survey for patients and clinicians. Inter-rater reliability of classification system. Setting Thirty-one National Health Service trusts. Participants Patients aged > 16 years referred for elective surgical treatment of pilonidal disease. Interventions Surgery. Main outcome measures Pain postoperative days 1 and 7, time to healing and return to normal activities, complications, recurrence. Outcomes compared between major and minor procedures using regression modelling, propensity score-based approaches and augmented inverse probability weighting to account for measured potential confounding features. Results Clinician survey: There was significant heterogeneity in surgeon practice preference. Limited training opportunities may impede efforts to improve practice. Cohort study: Over half of patients (60%; N = 667) had a major procedure. For these procedures, pain was greater on day 1 and day 7 (mean difference day 1 pain 1.58 points, 95% confidence interval 1.14 to 2.01 points, n = 536; mean difference day 7 pain 1.53 points, 95% confidence interval 1.12 to 1.95 points, n = 512). There were higher complication rates (adjusted risk difference 17.5%, 95% confidence interval 9.1 to 25.9%, n = 579), lower recurrence (adjusted risk difference -10.1%, 95% confidence interval -18.1 to -2.1%, n = 575), and longer time to healing (>34 days estimated difference) and time to return to normal activities (difference 25.9 days, 95% confidence interval 18.4 to 33.4 days). Mixed-methods analysis: Patient decision-making was influenced by prior experience of disease and anticipated recovery time. The burden involved in wound care and the gap between expected and actual time for recovery were the principal reasons given for decision regret. Discrete choice experiment: The strongest predictors of patient treatment choice were risk of infection/persistence (attribute importance 70%), and shorter recovery time (attribute importance 30%). Patients were willing to trade off these attributes. Those aged over 30 years had a higher risk tolerance (22.35-34.67%) for treatment failure if they could experience rapid recovery. There was no strong evidence that younger patients were willing to accept higher risk of treatment failure in exchange for a faster recovery. Patients were uniform in rejecting excision-and-leave-open because of the protracted nursing care it entailed. Wysocki classification analysis: There was acceptable inter-rater agreement (κ = 0.52, 95% confidence interval 0.42 to 0.61). Consensus exercise: Five research and practice priorities were identified. The top research priority was that a comparative trial should broadly group interventions. The top practice priority was that any interventions should be less disruptive than the disease itself. Limitations Incomplete recruitment and follow-up data were an issue, particularly given the multiple interventions. Assumptions were made regarding risk adjustment. Conclusions and future work Results suggest the burden of pilonidal surgery is greater than reported previously. This can be mitigated with better selection of intervention according to disease type and patient desired goals. Results indicate a framework for future higher-quality trials that stratify disease and utilise broad groupings of common interventions with development of a patient-centred core outcome set.

Surg Endosc 2024:10.1007/s00464-024-10951-3. [PMID: 38902411 DOI: 10.1007/s00464-024-10951-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 05/23/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND Despite evidence of benefits on postoperative outcomes, minimally invasive liver surgery (MILS) had a very low diffusion up to 2014, and recent evolution is unknown. Our aim was to analyze the recent diffusion and adoption of MILS and compare the trends in indications, extent of resection, and institutional practice with open liver surgery (OLS). METHODS We analyzed the French nationwide, exhaustive cohort of all patients undergoing a liver resection in France between January 1, 2013 and December 31, 2022. Average annual percentage changes (AAPC) in the incidence of MILS and OLS were compared using mixed-effects log-linear regression models. Time trends were analyzed in terms of extent of resection, indication, and institutional practice. RESULTS MILS represented 25.2% of 74,671 liver resections and year incidence doubled from 16.5% in 2013 to 35.4% in 2022. The highest AAPC were observed among major liver resections [+ 22.2% (19.5; 24.9) per year], primary [+ 10.2% (8.5; 12.0) per year], and secondary malignant tumors [+ 9.9% (8.2; 11.6) per year]. The highest increase in MILS was observed in university hospitals [+ 14.7% (7.7; 22.2) per year] performing 48.8% of MILS and in very high-volume (> 150 procedures/year) hospitals [+ 12.1% (9.0; 15.3) per year] performing 19.7% of MILS. OLS AAPC decreased for all indications and institutions and accelerated over time from - 1.8% (- 3.9; - 0.3) per year in 2013-2018 to - 5.9% (- 7.9; - 3.9) per year in 2018-2022 (p = 0.013). CONCLUSIONS This is the first reported trend reversal between MILS and OLS. MILS has considerably increased at a national scale, crossing the 20% tipping point of adoption rate as defined by the IDEAL framework.

Abstract
OBJECTIVE To report the developmental phase results of posterior rectus sheath hiatal flap augmentation (PoRSHA), a promising surgical innovation for large and recurrent paraesophageal hernias. BACKGROUND Durable hernia repair for large paraesophageal hernias continues to be a surgical challenge. PoRSHA addresses the challenges of current and historical approaches to complex paraesophageal hernias and demonstrates significant promise as a successful alternative approach. METHODS Using the IDEAL framework, we outline the technical modifications made over the first 27 consecutive cases using PoRSHA. Outcomes measured included hernia recurrence on routine imaging at 6 months and 2 years, development of a postoperative abdominal wall eventration and incidence of solid food dysphagia. RESULTS Twenty-seven patients at our single institution with type III (n=12), type IV (n=7), or recurrent (n=8) paraesophageal hernias underwent PoRSHA. Surgery was safely and successfully carried out in all cases. Stability of the technique was reached after 16 cases, resulting in 4 main repair types. At an average follow-up of 11 months, we observed no radiologic recurrences, no abdominal eventrations or hernias at the donor site, and 1 patient with occasional solid food dysphagia that resolved with dilation. CONCLUSIONS PoRSHA can not only be safely added to conventional hiatal hernia repair with appropriate training but also demonstrates excellent short-term outcomes. While the long-term durability with 5-year follow-up is still needed, here we provide cautious optimism that PoRSHA may represent a novel solution to the long-standing high recurrence rates observed with current complex PEH repair.

Abstract
OBJECTIVES The development of new surgical procedures is fundamental to advancing patient care. The Idea, Developments, Exploration, Assessment and Long-term (IDEAL) framework describes study designs for stages of innovation. It can be difficult to apply due to challenges in defining and identifying innovative procedures. This study examined how the IDEAL framework is operationalised in real-world settings; specifically, the types of innovations evaluated using the framework and how authors justify their choice of IDEAL study design. DESIGN Secondary qualitative analysis of a systematic review. DATA SOURCES Citation searches (Web of Science and Scopus) identified studies following the IDEAL framework and citing any of the ten key IDEAL/IDEAL_D papers. ELIGIBILITY CRITERIA Studies of invasive procedures/devices of any design citing any of the ten key IDEAL/IDEAL_D papers. DATA EXTRACTION AND SYNTHESIS All relevant text was extracted. Three frameworks were developed, namely: (1) type of innovation under evaluation; (2) terminology used to describe stage of innovation and (3) reported rationale for IDEAL stage. RESULTS 48 articles were included. 19/48 described entirely new procedures, including those used for the first time in a different clinical context (n=15/48), reported as IDEAL stage 2a (n=8, 53%). Terminology describing stage of innovation was varied, inconsistent and ambiguous and was not defined. Authors justified their choice of IDEAL study design based on limitations in published evidence (n=36) and unknown feasibility and safety (n=32) outcomes. CONCLUSION Identifying stage of innovation is crucial to inform appropriate study design and governance decisions. Authors' rationale for choice of IDEAL stage related to the existing evidence base or lack of sufficient outcome data for procedures. Stage of innovation was poorly defined with inconsistent descriptions. Further work is needed to develop methods to identify innovation to inform practical application of the IDEAL framework. Defining the concept of innovation in terms of uncertainty, risk and degree of evidence may help to inform decision-making.

MAIN OUTCOME MEASURES Five outcome domains were considered: nasolabial aesthetics; dentoalveolar relationship; midfacial growth; cost and burden of care; and number of anesthetic events. DESIGN MEDLINE, Embase, and Scopus were queried for articles from the first description of the Grayson-Santiago NAM technique (1993) through December 13, 2021. After the application of inclusionary and exclusionary criteria, selected articles were critically appraised using a systematic framework that included risk of bias assessment using the Cochrane RoB 2.0 and ROBINS-I tools. RESULTS A total of 88 studies were included. Level-I and -II evidence showed on par or better approximation and alveolar alignment achieved by NAM compared to other PSIO. Level-II and -III evidence showed improved nasolabial aesthetics compared to other PSIOs. Level-II and -III evidence supported no harm to maxillofacial skeletal growth through age 12. Sparse level-III evidence supported a reduced number of labial or nasal revisions following NAM. Level-II and -III evidence showed NAM requiring upfront cost and frequent appointments but reducing caregiver psychosocial burden and reducing long-term costs compared to select alternatives. Many studies carried a high risk of bias. CONCLUSIONS Current evidence supports the overall efficacy of NAM regarding short/mid-term outcomes, with a low risk of negative effects on midfacial growth or dental development. The high risk of bias discovered in many papers underscores the need for robust study design in future research.

Assessment of Advanced Diagnostic Bronchoscopy Outcomes for Peripheral Lung Lesions: A Delphi Consensus Definition of Diagnostic Yield and Recommendations for Patient-centered Study Designs. An Official American Thoracic Society/American College of Chest Physicians Research Statement. Am J Respir Crit Care Med 2024; 209:634-646. [PMID: 38394646 PMCID: PMC10945060 DOI: 10.1164/rccm.202401-0192st] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 02/23/2024] [Indexed: 02/25/2024] Open
Abstract
Background: Advanced diagnostic bronchoscopy targeting the lung periphery has developed at an accelerated pace over the last two decades, whereas evidence to support introduction of innovative technologies has been variable and deficient. A major gap relates to variable reporting of diagnostic yield, in addition to limited comparative studies. Objectives: To develop a research framework to standardize the evaluation of advanced diagnostic bronchoscopy techniques for peripheral lung lesions. Specifically, we aimed for consensus on a robust definition of diagnostic yield, and we propose potential study designs at various stages of technology development. Methods: Panel members were selected for their diverse expertise. Workgroup meetings were conducted in virtual or hybrid format. The cochairs subsequently developed summary statements, with voting proceeding according to a modified Delphi process. The statement was cosponsored by the American Thoracic Society and the American College of Chest Physicians. Results: Consensus was reached on 15 statements on the definition of diagnostic outcomes and study designs. A strict definition of diagnostic yield should be used, and studies should be reported according to the STARD (Standards for Reporting Diagnostic Accuracy Studies) guidelines. Clinical or radiographic follow-up may be incorporated into the reference standard definition but should not be used to calculate diagnostic yield from the procedural encounter. Methodologically robust comparative studies, with incorporation of patient-reported outcomes, are needed to adequately assess and validate minimally invasive diagnostic technologies targeting the lung periphery. Conclusions: This American Thoracic Society/American College of Chest Physicians statement aims to provide a research framework that allows greater standardization of device validation efforts through clearly defined diagnostic outcomes and robust study designs. High-quality studies, both industry and publicly funded, can support subsequent health economic analyses and guide implementation decisions in various healthcare settings.

Laparoscopic or open abdominal surgery with thoracotomy for patients with oesophageal cancer: ROMIO randomized clinical trial. Br J Surg 2024; 111:znae023.

Abstract
OBJECTIVE This study investigated if hybrid oesophagectomy with minimally invasive gastric mobilization and thoracotomy enabled faster recovery than open surgery. METHODS In eight UK centres, this pragmatic RCT recruited patients for oesophagectomy to treat localized cancer. Participants were randomly allocated to hybrid or open surgery, stratified by centre and receipt of neoadjuvant treatment. Large dressings aimed to mask patients to their allocation for six days post-surgery. The authors present the intention-to-treat analysis of outcome measures from the first 3 months post-randomization, including the primary outcome, the patient-reported physical function scale of the EORTC QLQ-C30, and cost-effectiveness. Current Controlled Trials registration: ISRCTN 59036820 (feasibility study), 10386621 (definitive study). FINDINGS There was no evidence of a difference between hybrid (n = 267) and open (n = 266) surgery in average physical function over 3 months post-randomization: difference in means 2.1, 95% c.i. -2.0 to 6.2, P = 0.3. Complication rates were similar; for example, 88 (34%) participants in the open and 82 (32%) participants in the hybrid surgery groups experienced a pulmonary infection within 30 days. There was no evidence that hybrid surgery was more cost-effective than open surgery at 3 months. CONCLUSIONS Patient-reported physical function in the 3 months post-randomization provided no evidence of a difference in recovery time between hybrid and open surgery, or a difference in cost-effectiveness. Both approaches to surgery were completed safely, with a similar risk of key complications, suggesting that surgeons who have a preference for one of the two approaches need not change their practice.

Abstract
The next generation of surgical robotics is poised to disrupt healthcare systems worldwide, requiring new frameworks for evaluation. However, evaluation during a surgical robot's development is challenging due to their complex evolving nature, potential for wider system disruption and integration with complementary technologies like artificial intelligence. Comparative clinical studies require attention to intervention context, learning curves and standardized outcomes. Long-term monitoring needs to transition toward collaborative, transparent and inclusive consortiums for real-world data collection. Here, the Idea, Development, Exploration, Assessment and Long-term monitoring (IDEAL) Robotics Colloquium proposes recommendations for evaluation during development, comparative study and clinical monitoring of surgical robots-providing practical recommendations for developers, clinicians, patients and healthcare systems. Multiple perspectives are considered, including economics, surgical training, human factors, ethics, patient perspectives and sustainability. Further work is needed on standardized metrics, health economic assessment models and global applicability of recommendations.

Abstract
PURPOSE To evaluate every stage of surgical innovation and generate high-quality research evidence, the IDEAL (Idea, Development, Exploration, Assessment, Long-term study) framework was developed. This study aimed to explore the application of the IDEAL framework in hepatopancreatobiliary surgery and identify factors limiting its dissemination. METHODS We conducted a citation search of 8 core IDEAL framework articles in PubMed, Embase, Web of Science, and Scopus databases from 2009 to 2022. Two independent reviewers screened and selected articles related to hepatopancreatobiliary surgery. RESULTS A total of 1621 articles were identified through citation search. Following screening, 132 articles were finally retained, including 75 original studies (57%) and 57 secondary studies (43%). Of the original studies, only 10 articles (13%) accurately applied the IDEAL framework in methodology, distributed as follows: 1 in pre-IDEAL stage (0), 2 in Idea stage (1), 7 in Development stage (2a), 1 in Exploration stage (2b), and no articles in Assessment and Long-term study stages (3, 4). In the secondary studies, 36 articles (63%) mentioned and discussed the IDEAL framework, and all supported its application. CONCLUSIONS The application of the IDEAL framework in hepatopancreatobiliary surgery is increasingly widespread, as evidenced by its substantial citation in numerous articles. However, the utilization of the IDEAL framework remains predominantly confined to the early stages of innovation in hepatopancreatobiliary surgery, coupled with instances of misapplication stemming from insufficient comprehension of the framework. Further efforts are necessary to extend the impact of the IDEAL framework and provide surgeons with comprehensive guidance for its judicious implementation.

Colorectal Dis 2023; 25:2346-2353. [PMID: 37919463 DOI: 10.1111/codi.16789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 09/06/2023] [Accepted: 09/08/2023] [Indexed: 11/04/2023]
Abstract
AIM There are several anastomotic techniques available to facilitate restorative rectal cancer surgery after total mesorectal excision (TME), including double-stapled anastomosis (DST) and handsewn coloanal anastomosis (CAA). However, to date no one technique is superior with regard to anastomotic leakage (AL) or functional outcomes. Transanal transection single-stapled anastomosis (TTSS) aims to overcome some of the technical challenges and offer comparable clinical and functional outcomes to traditional anastomotic techniques. The aim of this study was to explore the role of TTSS in modern rectal cancer surgery and to provide comparative clinical and functional outcome data with DST and CAA. METHOD A prospective cohort study was undertaken to assess the safety and clinical and patient-reported outcomes associated with the TTSS procedure. All patients undergoing sphincter-preserving surgery for rectal cancer with an anastomosis performed within 6 cm of the anal verge between January 2016 and April 2021 were prospectively enrolled into this study. Clinical and patient-reported outcome data, including low anterior resection syndrome (LARS) assessment, were collected. The primary endpoint was anastomotic leakage within 30 days. RESULTS A total of 275 patients participated in this study, with 70 (25%) patients undergoing a TTSS, 110 (40%) undergoing a DST and 95 (35%) undergoing a CAA. Patients undergoing a CAA had more distal tumours than those having a TTSS or DST, with a median tumour height of 5, 7 and 9 cm (p < 0.001), respectively. We observed a statistically significant reduction in AL in the TTSS group compared with the DST group, with rates of 8.6% versus 20.9% (p = 0.028). There was no difference in LARS scores between patients undergoing TTSS and DST (p = 0.228), while patients with a CAA had worse LARS scores than TTSS patients (p = 0.002). CONCLUSION TTSS is a technically safe and feasible anastomotic technique in rectal cancer surgery as an alternative to DST and CAA. Its advantages over DST are a reduced AL rate and, over CAA, improved function. It should therefore be considered as an alternative technique to improve clinical and patient-reported outcomes in restorative rectal cancer surgery.

Abstract
BACKGROUND AND PURPOSE Radiotherapy for vulvar carcinoma is challenging due to relatively high risk of locoregional disease recurrence, a technically challenging target, and postoperative lymphocele, and a high risk radiation sequelae. We aim to explore, if it is possible to reduce dose to normal tissue, while maintaining CTV coverage for this patient group with online adaptive radiotherapy. MATERIALS AND METHODS 20 patients with vulvar carcinoma (527 fractions) were treated with online adaptation on a Varian Ethos accelerator. Setup CBCTs were acquired daily for adaptive planning. Verification CBCTs were acquired immediately prior to dose delivery. CTV dose coverage and dose to bladder and rectum were extracted from the scheduled and adapted plans as well as from adapted plans recalculated based on verification CBCTs. In addition, analysis of the decision of the adaptive procedure was performed for 17 patients (465 fractions). RESULTS Mean CTV D95% and standard deviation was 98% ± 5% for the scheduled plan compared to 100.0 ± 0.3% and 100.0 ± 0.8% for the adapted plan on the setup and verification CBCT respectively. Dose to OARs varied substantially and did not show any benefit from adaption itself, however a margin reduction was implemented after the first patients treated. The adapted plan was chosen for 63.5% of the fractions and dominant reasons for not adapting were 'no significant dosimetric gain' (75 fractions, 14%) and 'Medical doctor (MD) not available for treatment' (50 fractions, 9.5%). The median adaption time was 15 min and the 25th and 75th percentile was 12 and 17 min, respectively. CONCLUSION CTVs and PTVs dose coverage were significantly improved with adaptation compared to image-guided RT. This gain was robust during the treatment time.

Closure of pelvic peritoneum with bladder peritoneum flap reconstruction after laparoscopic extralevator abdominoperineal excision: A prospective stage II study. J Surg Oncol 2023; 128:851-859. [PMID: 37462103 DOI: 10.1002/jso.27382] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/14/2023] [Accepted: 06/19/2023] [Indexed: 09/11/2023]
Abstract
BACKGROUND Extralevator abdominoperineal resection (ELAPE) has increased perineal wound complications due to the extended resection area. Closure of the pelvic peritoneum (CPP) may exclude the abdominal content from descending into the pelvic cavity and reduce the incidence of perineal complications after ELAPE. We have previously introduced bladder peritoneum flap reconstruction (BLAPER) as a novel method for patients in whom traditional CPP is not possible. The aim of the present study was to report the development and preliminary outcomes of BLAPER. METHODS This is a prospective single-arm study at the development and exploration phase and fulfills the IDEAL framework stage II. Ultralow rectal cancer patients with rigid pelvis who underwent ELAPE with BLAPER were enrolled. Primary outcomes were intraoperative complications and postoperative complications within 1 month after surgery. RESULTS Among 27 patients included, the overall success rate of BLAPER was 96.3% (26/27). Indocyanine green fluorescence imaging and antiadhesive barrier placement were introduced to improve the BLAPER technique. The incidence of major pelvic wound complications was 7.7%. No patient who underwent BLAPER has suffered small bowel obstruction (SBO), presence of small bowel in the retrourogenital space, or perineal hernia (PH). CONCLUSIONS BLAPER is safe and may prevent the small bowel from descending into the retrourogenital space and subsequently developing PH and SBO without increasing the intraoperative and postoperative complications. BLAPER may serve as an option when the primary suture of the pelvic peritoneum is not feasible.

Abstract
BACKGROUND The anatomy laboratory can provide the ideal setting for the preclinical phase of neurosurgical research. Our purpose is to comprehensively and critically review the preclinical anatomical quantification methods used in cranial neurosurgery. METHODS A systematic review was conducted following the PRISMA guidelines. The PubMed, Ovid MEDLINE, and Ovid EMBASE databases were searched, yielding 1667 papers. A statistical analysis was performed using R. RESULTS The included studies were published from 1996 to 2023. The risk of bias assessment indicated high-quality studies. Target exposure was the most studied feature (81.7%), mainly with area quantification (64.9%). The surgical corridor was quantified in 60.9% of studies, more commonly with the quantification of the angle of view (60%). Neuronavigation-based methods benefit from quantifying the surgical pyramid features that define a cranial neurosurgical approach and allowing post-dissection data analyses. Direct measurements might diminish the error that is inherent to navigation methods and are useful to collect a small amount of data. CONCLUSION Quantifying neurosurgical approaches in the anatomy laboratory provides an objective assessment of the surgical corridor and target exposure. There is currently limited comparability among quantitative neurosurgical anatomy studies; sharing common research methods will provide comparable data that might also be investigated with artificial intelligence methods.

Abstract
Context Identifying malignant tissue and leaving adjacent structures undisturbed constitute an ongoing challenge in prostate cancer (PCa) surgery. Image and radioguided surgical technologies targeting the prostate-specific membrane antigen (PSMA) receptor may facilitate identification and removal of diseased tissue. Objective To perform a systematic review of the clinical studies on PSMA-targeted surgery. Evidence acquisition The MEDLINE (OvidSP), Embase.com, and Cochrane Library databases were searched. Identified reports were critically appraised according to the Idea, Development, Exploration, Assessment, Long-term framework criteria. The risk of bias (RoB) was assessed as per the Risk Of Bias In Non-randomized Studies-of Interventions tool. The strengths and limitations of the techniques and corresponding oncological outcomes were extracted as areas of interest. Data were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Evidence synthesis In total, 29 reports were selected, including eight prospective studies, 12 retrospective analyses, and nine case reports, all with a high or an unclear RoB. In 72.4% of studies, PSMA targeting was achieved via radioguided surgery (RGS), predominantly using 99mTc-PSMA-I&S (66.7%). Hybrid approaches that complement RGS with optical guidance are emerging. The majority of studies retrieved were pilot studies with a short follow-up. In 13 reports, salvage lymph node surgery was discussed (44.8%). In 12 more recent reports (41.4%), PSMA targeting was studied in primary PCa surgery (50.0% lymph nodes and 50.0% surgical margins), and four studied both primary and salvage surgery (13.8%). Overall, specificity was higher than sensitivity (median 98.9% and 84.8%, respectively). Oncological outcomes were discussed only in reports on the use of 99mTc-PSMA-I&S in salvage surgery (median follow-up of 17.2 mo). A decline in prostate-specific antigen level of >90% ranged from 22.0% to 100.0%, and biochemical recurrence ranged from 50.0% to 61.8% of patients. Conclusions In PSMA-targeted surgery, most studies address salvage PSMA-RGS using 99mTc-PSMA-I&S. Available evidence suggests that the specificity of intraoperative PSMA targeting is higher than the sensitivity. The studies that included follow-up did not yet objectify a clear oncological benefit. Lacking solid outcome data, PSMA-targeted surgery remains investigational. Patient summary In this paper, we review recent advances in prostate-specific membrane antigen (PSMA)-targeted surgery, which is used to help identify and remove prostate cancer. We found good evidence to suggest that PSMA targeting helps identify prostate cancer during surgery. The oncological benefits have yet to be investigated further.

Learning curves in laparoscopic distal pancreatectomy: a different experience for each generation. Int J Surg 2023; 109:1648-1655. [PMID: 37144678 PMCID: PMC10389345 DOI: 10.1097/js9.0000000000000408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 04/06/2023] [Indexed: 05/06/2023]
Abstract
BACKGROUND Learning curves of laparoscopic distal pancreatectomy (LDP) are mostly based on 'self-taught' surgeons who acquired sufficient proficiency largely through self-teaching. No learning curves have been investigated for 'trained' surgeons who received training and built on the experience of the 'self-taught' surgeons. This study compared the learning curves and outcome of LDP between 'self-taught' and 'trained' surgeons in terms of feasibility and proficiency using short-term outcomes. MATERIALS AND METHODS Data of consecutive patients with benign or malignant disease of the left pancreas who underwent LDP by four 'self-taught' and four 'trained' surgeons between 1997 and 2019 were collected, starting from the first patient operated by a contributing surgeon. Risk-adjusted cumulative sum (RA-CUSUM) analyses were performed to determine phase-1 feasibility (operative time) and phase-2 proficiency (major complications) learning curves. Outcomes were compared based on the inflection points of the learning curves. RESULTS The inflection points for the feasibility and proficiency learning curves were 24 and 36 procedures for 'trained' surgeons compared to 64 and 85 procedures for 'self-taught' surgeons, respectively. In 'trained' surgeons, operative time was reduced after completion of the learning curves (230.5-203 min, P= 0.028). In 'self-taught' surgeons, operative time (240-195 min, P ≤0.001), major complications (20.6-7.8%, P= 0.008), and length of hospital stay (9-5 days, P ≤0.001) reduced after completion of the learning curves. CONCLUSION This retrospective international cohort study showed that the feasibility and proficiency learning curves for LDP of 'trained' surgeons were at least halved as compared to 'self-taught' surgeons.

Trials 2023; 24:294.

Abstract
BACKGROUND Surgical interventions are complex. Key elements of this complexity are the surgeon and their learning curve. They pose methodological challenges in the design, analysis and interpretation of surgical RCTs. We identify, summarise, and critically examine current guidance about how to incorporate learning curves in the design and analysis of RCTs in surgery. EXAMINING CURRENT GUIDANCE Current guidance presumes that randomisation must be between levels of just one treatment component, and that the evaluation of comparative effectiveness will be made via the average treatment effect (ATE). It considers how learning effects affect the ATE, and suggests solutions which seek to define the target population such that the ATE is a meaningful quantity to guide practice. We argue that these are solutions to a flawed formulation of the problem, and are inadequate for policymaking in this setting. REFORMULATING THE PROBLEM The premise that surgical RCTs are limited to single-component comparisons, evaluated via the ATE, has skewed the methodological discussion. Forcing a multi-component intervention, such as surgery, into the framework of the conventional RCT design ignores its factorial nature. We briefly discuss the multiphase optimisation strategy (MOST), which for a Stage 3 trial would endorse a factorial design. This would provide a wealth of information to inform nuanced policy but would likely be infeasible in this setting. We discuss in more depth the benefits of targeting the ATE conditional on operating surgeon experience (CATE). The value of estimating the CATE for exploring learning effects has been previously recognised, but with discussion limited to analysis methods only. The robustness and precision of such analyses can be ensured via the trial design, and we argue that trial designs targeting CATE represent a clear gap in current guidance. CONCLUSION Trial designs that facilitate robust, precise estimation of the CATE would allow for more nuanced policymaking, leading to patient benefit. No such designs are currently forthcoming. Further research in trial design to facilitate the estimation of the CATE is needed.

Abstract
PURPOSE To analyze the safety and feasibility of intracorporeal resection and anastomosis in upper rectum, sigmoid, and left colon surgery, via both laparoscopic and robotic approaches. The secondary aim was to assess possible short-term differences between laparoscopic versus robotic surgery. METHODS A prospective observational cohort study according to IDEAL framework exploration and assessment stage (Development, stage 2a), evaluating and comparing the laparoscopic approach and the robotic approach in left colon, sigmoid, and upper rectum surgery with intracorporeal resection and end-to-end anastomosis. Demographic, preoperative, surgical, and postoperative variables of patients undergoing laparoscopic and robotic surgery are described and compared according to the surgical technique used. RESULTS Between May 2020 and March 2022, seventy-nine patients were consecutively included in the study, 41 operated via laparoscopy (laparoscopic left colectomy: LLC) and 38 by robotic surgery (robotic left colectomy: RLC). There were no statistically significant differences between the two groups in terms of demographic variables. In surgical variables, the median surgical times differed significantly: 198 min (SD 48 min) for LLC vs. 246 min (SD 72 min) for RLC (p = 0.01, 95% CI: - 75.2 to - 20.5)). The only significant difference regarding postoperative complications was a higher degree of relevant morbidity in the LLC (Clavien-Dindo > II (14.6% vs. 0%, p = 0.03) and Comprehensive Complication Index (IQR 22 vs. IQR 0, p = 0.03). The pathological results were similar in both approaches. CONCLUSION Laparoscopic and robotic intracorporeal resection and anastomosis are feasible and safe, and obtain similar surgical, postoperative, and pathological results than described in literature. However, morbidity seems to be higher in LLC group with fewer relevant postoperative complications. The results of this study enable us to proceed to stage 2b of the IDEAL framework. CLINICAL TRIAL REGISTRATIONS The study is registered in Clinical trials with the registration code NCT0445693.

Abstract
BACKGROUND Surgical excision of a non-palpable breast lesion requires a localization step. Among available techniques, wire-guided localization (WGL) is most commonly used. Other techniques (radioactive, magnetic, radar or radiofrequency-based, and intraoperative ultrasound) have been developed in the last two decades with the aim of improving outcomes and logistics. METHODS We performed a systematic review on localization techniques for non-palpable breast cancer. RESULTS For most techniques, oncological outcomes such as lesion identification and clear margin rate seem either comparable with or better than for WGL, but evidence is limited to small cohort studies for some of the devices. Intraoperative ultrasound is associated with significantly higher negative margin rates in meta-analyses of randomized clinical trials (RCTs). Radioactive techniques were studied in several RCTs and are non-inferior to WGL. Smaller studies show higher patient preference towards wire-free localization, but little is known about surgeons' and radiologists' attitudes towards these techniques. CONCLUSIONS Large studies with an additional focus on patient, surgeon, and radiologist preference are necessary. This review aims to present the rationale for the MELODY (NCT05559411) study and to enable standardization of outcome measures for future studies.

Abstract
OBJECTIVE During development of complex surgical innovations, modifications occur to optimize safety and efficacy. Operators' experiences (how professionals feel undertaking the innovation) drive this process but comprehensive overviews of measures of this concept are lacking. This study identified and appraised measures to assess operators' experience of surgical innovation. STUDY DESIGN AND SETTING There were three phases: (1) Literature reviews identified measures of operators' experience and concepts measured were extracted and grouped into domains. (2) Quality appraisal was conducted to assess content validity of identified instruments and was supported by COnsensus-based Standards for the selection of health Measurement Instruments methodology. Self-reported measurement instruments that had underdone formal development were eligible. Content validity was assessed using COnsensus-based Standards for the selection of health Measurement Instruments criteria for good content validity (rated sufficient/insufficient/indeterminate/inconsistent), informed by standards for measurement development and domains identified in phase 1. (3) Instruments determined suitable and of sufficient quality underwent supplemental appraisal in interviews with international multidisciplinary professionals and a focus group. RESULTS Literature reviews identified 16 measurement instruments from 243 studies. Most assessed 'psychological' experiences and 'usability'. No instrument was specifically validated for innovative surgery. Three instruments were rated 'sufficient' (Surgery Task Load Index [SURG-TLX]) or 'indeterminate' (Spielberger State-Trait Anxiety Inventory, Imperial Stress Assessment Tool). Twenty professionals were interviewed (seven female; 15 specialties; six countries) and the focus group included 10 participants (four professionals, six researchers). The SURG-TLX was considered the most relevant, comprehensive, and comprehensible instrument. CONCLUSION The SURG-TLX is preliminarily recommended to measure operators' experiences of innovation. Further work exploring its role and impact on surgical innovation is required.

The Idea, Development, Exploration, Assessment and Long-term (IDEAL) framework proposes preliminary prospective collaborative cohort studies with specific properties (IDEAL 2b studies) to increase the quality and feasibility of surgical RCTs. Little empirical evidence exists for this proposition, and specifically designed 2b studies are currently uncommon. Prospective collaborative cohort studies are, however, relatively common, and might provide similar benefits. We will, therefore, assess the association between prior ‘IDEAL 2b-like’ cohort studies and the quality and impact of surgical RCTs.We propose a systematic review using two parallel case–control analyses, with surgical RCTs as subjects and study quality and journal impact factor (IF) as the outcomes of interest. We will search for surgical RCTs published between 2015 and 2019 and and prior prospective collaborative cohort studies authored by any of the RCT investigators. RCTs will be categorized into cases or controls by (1) journal (IF ≥or <5) and (2) study quality (PEDro score ≥or < 7). The case/control OR of exposure to a prior ‘2b like’ study will be calculated independently for quality and impact. Cases will be matched 1: 1 with controls by year of publication, and confounding by peer-reviewed funding, author academic affiliation and trial protocol registration will be examined using multiple logistic regression analysis.This study will examine whether preparatory IDEAL 2b-like studies are associated with higher quality and impact of subsequent RCTs.

Group sequential designs in pragmatic trials: feasibility and assessment of utility using data from a number of recent surgical RCTs. BMC Med Res Methodol 2022; 22:256. [PMID: 36183085 PMCID: PMC9526271 DOI: 10.1186/s12874-022-01734-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 09/16/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Assessing the long term effects of many surgical interventions tested in pragmatic RCTs may require extended periods of participant follow-up to assess effectiveness and use patient-reported outcomes that require large sample sizes. Consequently the RCTs are often perceived as being expensive and time-consuming, particularly if the results show the test intervention is not effective. Adaptive, and particularly group sequential, designs have great potential to improve the efficiency and cost of testing new and existing surgical interventions. As a means to assess the potential utility of group sequential designs, we re-analyse data from a number of recent high-profile RCTs and assess whether using such a design would have caused the trial to stop early. METHODS Many pragmatic RCTs monitor participants at a number of occasions (e.g. at 6, 12 and 24 months after surgery) during follow-up as a means to assess recovery and also to keep participants engaged with the trial process. Conventionally one of the outcomes is selected as the primary (final) outcome, for clinical reasons, with others designated as either early or late outcomes. In such settings, novel group sequential designs that use data from not only the final outcome but also from early outcomes at interim analyses can be used to inform stopping decisions. We describe data from seven recent surgical RCTs (WAT, DRAFFT, WOLLF, FASHION, CSAW, FIXDT, TOPKAT), and outline possible group sequential designs that could plausibly have been proposed at the design stage. We then simulate how these group sequential designs could have proceeded, by using the observed data and dates to replicate how information could have accumulated and decisions been made for each RCT. RESULTS The results of the simulated group sequential designs showed that for two of the RCTs it was highly likely that they would have stopped for futility at interim analyses, potentially saving considerable time (15 and 23 months) and costs and avoiding patients being exposed to interventions that were either ineffective or no better than standard care. We discuss the characteristics of RCTs that are important in order to use the methodology we describe, particularly the value of early outcomes and the window of opportunity when early stopping decisions can be made and how it is related to the length of recruitment period and follow-up. CONCLUSIONS The results for five of the RCTs tested showed that group sequential designs using early outcome data would have been feasible and likely to provide designs that were at least as efficient, and possibly more efficient, than the original fixed sample size designs. In general, the amount of information provided by the early outcomes was surprisingly large, due to the strength of correlations with the primary outcome. This suggests that the methods described here are likely to provide benefits more generally across the range of surgical trials and more widely in other application areas where trial designs, outcomes and follow-up patterns are structured and behave similarly.

Shared Learning Utilizing Digital Methods in Surgery to Enhance Transparency in Surgical Innovation: Protocol for a Scoping Review. JMIR Res Protoc 2022; 11:e37544. [PMID: 36074555 PMCID: PMC9501681 DOI: 10.2196/37544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 08/11/2022] [Accepted: 08/16/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Surgical innovation can lead to important improvements in patient outcomes. Currently, information and knowledge about novel procedures and devices are disseminated informally and in an unstandardized way (eg, through social media). This can lead to ineffective and inefficient knowledge sharing among surgeons, which can result in the harmful repetition of mistakes and delay in the uptake of promising innovation. Improvements are needed in the way that learning in surgical innovation is shared through the development of novel, real-time methods, informed by a contemporary and comprehensive investigation of existing methods. OBJECTIVE The aim of this scoping review is to explore the application of existing digital methods for training/education and feedback to surgeons in the context of performing invasive surgical procedures. This work will (1) summarize existing methods for shared learning in surgery and how they are characterized and operationalized, (2) examine the impact of their application, and (3) explore their benefits and barriers to implementation. The findings of this scoping review will inform the development of novel, real-time methods to optimize shared learning in surgical innovation. METHODS This study will adhere to the recommended guidelines for conducting scoping reviews. A total of 6 different searches will be conducted within multiple sources (2 electronic databases, journals, social media, gray literature, commercial websites, and snowball searches) to comprehensively identify relevant articles and data. Searches will be limited to articles published in the English language within the last 5 years. Wherever possible, a 2-stage study selection process will be followed whereby the eligibility of articles will be assessed through the title, abstract, and full-text screening independently by 2 reviewers. Inclusion criteria will be articles providing data on (1) fully qualified theater staff involved in performing invasive procedures, (2) one or more methods for shared learning (ie, digital means for training/education and feedback), and (3) qualitative or quantitative evaluations of this method. Data will be extracted (10% double data extraction by an independent reviewer) into a piloted proforma and analyzed using descriptive statistics, narrative summaries, and principles of thematic analysis. RESULTS The study commenced in October 2021 and is planned to be completed in 2023. To date, systematic searches were applied to 2 electronic databases (MEDLINE and Web of Science) and returned a total of 10,093 records. The results of this scoping review will be published as open access in a peer-reviewed journal. CONCLUSIONS This scoping review of methods for shared learning in surgery is, to our knowledge, the most comprehensive and up-to-date investigation that maps current information on this topic. Ultimately, efficient and effective sharing of information and knowledge of novel procedures and devices has the potential to optimize the evaluation of early-phase surgical research and reduce harmful innovation.

Abstract
IntroductionCurrently, the majority of prostate cancer (PCa) recurrences after non-surgical first-line treatment are managed with androgen-deprivation therapy (ADT). Salvage radical prostatectomy (sRP) is a curative alternative to ADT but yields significant morbidity. Preliminary evidence from focal salvage treatments shows similar oncological control but lower morbidity compared to sRP. Among available ablative focal energies, irreversible electroporation (IRE) is a treatment modality that proved promising, especially in treating apical lesions, where PCa most often recurs. Our aim is to test the safety of salvage IRE for recurrent PCa.MethodsWe performed a single-arm pilot feasibility study (IDEAL stage 2a): SAFE, SAlvage Focal irreversible Electroporation for recurrent localized PCa. Twenty patients with biopsy-proven PCa recurrence after primary non-surgical (radiation or ablation) treatment were included. All men will undergo mpMRI ± targeted biopsies, pre-operative PSMA-PET staging before inclusion and sIRE. Outcomes will be evaluated through internationally validated questionnaires and morbidity scales. All men will undergo a control biopsy at one year.ResultsPrimary objectives were the evaluation of the safety of sIRE (and patients’ quality of life) after treatment. Secondary objectives were the evaluation of functional outcomes, namely, continence and erectile function changes and evaluation of short-term oncological efficacy.ConclusionsSAFE is the second pilot study to evaluate sIRE and the first one performed according to the most recent diagnostic and staging imaging standards. sIRE may provide a curative option for recurrent PCa together with lower comorbidities compared to sRP.

Abstract
AIMS The aim of this study was to inform the epidemiology and treatment of slipped capital femoral epiphysis (SCFE). METHODS This was an anonymized comprehensive cohort study, with a nested consented cohort, following the the Idea, Development, Exploration, Assessment, Long-term study (IDEAL) framework. A total of 143 of 144 hospitals treating SCFE in Great Britain participated over an 18-month period. Patients were cross-checked against national administrative data and potential missing patients were identified. Clinician-reported outcomes were collected until two years. Patient-reported outcome measures (PROMs) were collected for a subset of participants. RESULTS A total of 486 children (513 hips) were newly affected, with a median of two patients (interquartile range 0 to 4) per hospital. The annual incidence was 3.34 (95% confidence interval (CI) 3.01 to 3.67) per 100,000 six- to 18-year-olds. Time to diagnosis in stable disease was increased in severe deformity. There was considerable variation in surgical strategy among those unable to walk at diagnosis (66 urgent surgery vs 43 surgery after interval delay), those with severe radiological deformity (34 fixation with deformity correction vs 36 without correction) and those with unaffected opposite hips (120 prophylactic fixation vs 286 no fixation). Independent risk factors for avascular necrosis (AVN) were the inability of the child to walk at presentation to hospital (adjusted odds ratio (aOR) 4.4 (95% CI 1.7 to 11.4)) and surgical technique of open reduction and internal fixation (aOR 7.5 (95% CI 2.4 to 23.2)). Overall, 33 unaffected untreated opposite hips (11.5%) were treated for SCFE by two-year follow-up. Age was the only independent risk factor for contralateral SCFE, with age under 12.5 years the optimal cut-off to define 'at risk'. Of hips treated with prophylactic fixation, none had SCFE, though complications included femoral fracture, AVN, and revision surgery. PROMs demonstrated the marked impact on quality of life on the child because of SCFE. CONCLUSION The experience of individual hospitals is limited and mechanisms to consolidate learning may enhance care. Diagnostic delays were common and radiological severity worsened with increasing time to diagnosis. There was unexplained variation in treatment, some of which exposes children to significant risks that should be evaluated through randomized controlled trials.

Abstract
Aims The aim of this study was to evaluate the epidemiology and treatment of Perthes’ disease of the hip. Methods This was an anonymized comprehensive cohort study of Perthes’ disease, with a nested consented cohort. A total of 143 of 144 hospitals treating children’s hip disease in the UK participated over an 18-month period. Cases were cross-checked using a secondary independent reporting network of trainee surgeons to minimize those missing. Clinician-reported outcomes were collected until two years. Patient-reported outcome measures (PROMs) were collected for a subset of participants. Results Overall, 371 children (396 hips) were newly affected by Perthes’ disease arising from 63 hospitals, with a median of two patients (interquartile range 1.0 to 5.5) per hospital. The annual incidence was 2.48 patients (95% confidence interval (CI) 2.20 to 2.76) per 100,000 zero- to 14-year-olds. Of these, 117 hips (36.4%) were treated surgically. There was considerable variation in the treatment strategy, and an optimized decision tree identified joint stiffness and age above eight years as the key determinants for containment surgery. A total of 348 hips (88.5%) had outcomes to two years, of which 227 were in the late reossification stage for which a hip shape outcome (Stulberg grade) was assigned. The independent predictors of a poorer radiological outcome were female sex (odds ratio (OR) 2.27 (95% CI 1.19 to 4.35)), age above six years (OR 2.62 (95% CI (1.30 to 5.28)), and over 50% radiological collapse at inclusion (OR 2.19 (95% CI 0.99 to 4.83)). Surgery had no effect on radiological outcomes (OR 1.03 (95% CI 0.55 to 1.96)). PROMs indicated the marked effect of the disease on the child, which persisted at two years. Conclusion Despite the frequency of containment surgery, we found no evidence of improved outcomes. There appears to be a sufficient case volume and community equipoise among surgeons to embark on a randomized clinical trial to definitively investigate the effectiveness of containment surgery.

Pancreaticojejunostomy without pancreatic duct stent after laparoscopic pancreatoduodenectomy: preliminary outcomes from a prospective randomized controlled trial. Surg Endosc 2022; 36:3629-3636. [PMID: 34993588 DOI: 10.1007/s00464-021-08909-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Accepted: 11/21/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND Outcomes of pancreaticojejunostomy without pancreatic duct during open pancreaticoduodenectomy (OPD) are unknown and controversial, and corresponding reports in laparoscopic surgery are lacking. METHODS Patients were evaluated at West China Hospital, and standard laparoscopic pancreaticoduodenectomy (LPD) was planned. A prospective randomized trial was conducted, in which the patients were randomly assigned to the no-stent and internal-stent groups in a single-center trial. The primary outcomes were the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) and 90-day mortality. Preliminary results were reported. RESULTS From November 2019 to March 2021, we enrolled 90 patients (41 in the no-stent group and 49 in the internal-stent group) in the study. All baseline parameters of both groups, including age, sex ratio, pancreatic duct diameter, and intraoperative blood loss, were comparable between the two groups except for pathological diagnosis and the texture of remnants. Twenty-seven (65.9%) and 19 (38.8%) patients in the no-stent and internal-stent groups, respectively, had soft pancreatic remnants (P = 0.010). The total incidence of CR-POPF was 5.6% and included two patients (4.9%) in the no-stent group and three patients (6.1%) in the internal-stent group (P = 1.000). Only one patient in the internal-stent group died of heart failure within 90 days after the operation. No significant difference in other postoperative complications was observed between the groups except for biochemical fistula [no-stent group vs. internal-stent group = 31.7% vs. 12.2%, (P = 0.024)]. CONCLUSIONS In a high-volume LPD center, duct-to-mucosa pancreaticojejunostomy without pancreatic duct stent is safe and reliable. In addition, duct-to-mucosa pancreaticojejunostomy without pancreatic duct stent was more challenge. We recommend using the stent during anastomosis and pulling it out after the procedure.

Abstract
OBJECTIVE To extend the IDEAL framework for device innovation, IDEAL-D, to include the preclinical stage of development (stage 0). BACKGROUND In previous work, the IDEAL collaboration has proposed frameworks for new surgical techniques and complex therapeutic technologies, the central tenet being that development and evaluation can and should proceed together in an ordered and logical manner that balances innovation and safety. METHODS Following agreement at the IDEAL Collaboration Council, a multidisciplinary working group was formed comprising 12 representatives from healthcare, academia, industry, and a patient advocate. The group conducted a series of discussions following the principles used in the development of the original IDEAL framework. Importantly, IDEAL aims for maximal transparency, optimal validity in the evaluation of primary effects, and minimization of potential risk to patients or others. The proposals were subjected to further review and editing by members of the IDEAL Council before a final consensus version was adopted. RESULTS In considering which studies are required before a first-in-human study, we have: (1) classified devices according to what they do and the risks they carry, (2) classified studies according to what they show about the device, and (3) made recommendations based on the principle that the more invasive and high risk a device is, the greater proof required of their safety and effectiveness before progression to clinical studies (stage 1). CONCLUSIONS The proposed recommendations for preclinical evaluation of medical devices represent a proportionate and pragmatic approach that balances the de-risking of first-in-human translational studies against the benefits of rapid translation of new devices into clinical practice.

Abstract
INTRODUCTION Innovation in surgery drives improvements to patient care. New surgical procedures and devices typically undergo a series of modifications as they are developed and refined during their introduction into clinical practice. These changes should ideally be reported and shared between surgeon-innovators to promote efficient, safe and transparent innovation. Currently, agreement on how modifications should be defined, conceptualised and classified, so they can be reported and shared efficiently and transparently, is lacking. The aim of this review is to examine and summarise existing literature on definitions, perceptions and classifications of modifications to surgical procedures/devices, including views on how to measure and report them. The findings will inform future work to standardise reporting and sharing of modifications in surgical innovation. MATERIALS AND METHODS A systematic scoping review will be conducted adhering to PRISMA-ScR guidelines. Included articles will focus on review articles and opinion pieces relevant to modifications to new surgical procedures or devices introduced to clinical practice. Methods to identify relevant literature will include systematic searches in MEDLINE (Ovid version), targeted internet searches (Google Scholar) and snowball searches. A two-stage screening process (titles/abstracts/keywords and full-texts) will use specified exclusion/inclusion criteria to identify eligible articles. Data on how modifications are i) defined, ii) perceived, and iii) classified, and iv) views on how modifications should be measured and reported, will be extracted verbatim. Inductive thematic analysis will be applied to extracted data where appropriate. Results will be presented as a narrative summary including descriptive characteristics of included articles. Findings will inform a preliminary conceptual framework to facilitate the systematic reporting and sharing of modifications to novel procedures and devices. HIGHLIGHTS This work will generate an in-depth understanding of how modifications are currently defined, perceived and classified, and views on how they may be reported, in the context of surgical innovation.Rigorous and comprehensive search methods will be applied to identify a wide range of diverse data sources for inclusion in the review.A summary of existing relevant literature on modifications is a necessary step to inform development of a framework for transparent, real-time reporting and sharing of modifications in future studies of innovative invasive procedures/devices.

Postoperative Outcomes After Laparoscopic Liver Resections in Low and High-Volume Centers: A Multicentric Case-Matched Comparative Study. World J Surg 2021; 46:362-369. [PMID: 34734322 DOI: 10.1007/s00268-021-06369-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/24/2021] [Indexed: 12/07/2022]
Abstract
BACKGROUND Laparoscopic liver resection (LLR) is the gold standard for liver resections. Despite its feasibility and safety in high-volume centers (HVC), its performance is controversial in low-volume centers (LVCs). We aimed to evaluate the results of LLR performed in LVC. METHODS Patients who underwent LLR between 2013 and 2019 in three LVCs were compared after case-matching with those in an HVC using the Institut Mutualiste Montsouris LLR Difficulty Score (IMMLDS). RESULTS Seventy-six patients treated in three LVCs were matched to 152 in HVCs for age, body mass index, and resection type. The incidence of LLR significantly increased in LVCs over time (2013-2016 vs. 2017-2019) (21.2% vs. 39.3%; p = 0.002 and) while abdominal drainage rate decreased (77.4% vs. 51.1%; p = 0.003). In IMMLDS group I (60 vs. 120 patients), higher Pringle maneuver (43.3% vs. 2.5%; p < 0.0001), median blood loss (175 ml vs. 50 ml; p < 0.0001), abdominal drainage (58.3% vs. 6.6%; p < 0.0001), and conversion rate (8.3% vs. 1.6%, p = 0.04) were observed in LVCs. The overall postoperative morbidity was comparable (Clavien I-II: p = 0.54; Clavien > II: p = 0.71). In IMMLDS groups II-III, Pringle maneuver (56.5% vs. 3.1%; p < 0.0001), blood loss (350 ml vs. 175 ml; p = 0.02), and abdominal drainage (75% vs. 28.3%; p = 0.004) were different; however, postoperative morbidity was not. The surgical difficulty notwithstanding, length of stay (group I: p = 0.13; group II-III: p = 0.93) and R0 surgical margin (group I: p = 0.3; group II-III p = 0.39) were not different between LVCs and HVCs. CONCLUSIONS LLR performed at an LVC can be feasible and safe with acceptable morbidity.

Abstract
There has been a significant rise in robotic trajectory guidance devices that have been utilised for stereotactic neurosurgical procedures. These devices have significant costs and associated learning curves. Previous studies reporting devices usage have not undertaken prospective parallel-group comparisons before their introduction, so the comparative differences are unknown. We study the difference in stereoelectroencephalography electrode implantation time between a robotic trajectory guidance device (iSYS1) and manual frameless implantation (PAD) in patients with drug-refractory focal epilepsy through a single-blinded randomised control parallel-group investigation of SEEG electrode implantation, concordant with CONSORT statement. Thirty-two patients (18 male) completed the trial. The iSYS1 returned significantly shorter median operative time for intracranial bolt insertion, 6.36 min (95% CI 5.72–7.07) versus 9.06 min (95% CI 8.16–10.06), p = 0.0001. The PAD group had a better median target point accuracy 1.58 mm (95% CI 1.38–1.82) versus 1.16 mm (95% CI 1.01–1.33), p = 0.004. The mean electrode implantation angle error was 2.13° for the iSYS1 group and 1.71° for the PAD groups (p = 0.023). There was no statistically significant difference for any other outcome. Health policy and hospital commissioners should consider these differences in the context of the opportunity cost of introducing robotic devices.

Abstract
Background Transanal total mesorectal excision (TaTME) is an innovative technique for distal rectal cancer dissection. It has been shown to have similar short-term outcomes to conventional open and laparoscopic total mesorectal excision (cTME), but recent studies have raised concern about increased morbidity and local recurrence rates. The aim of this study was to assess outcomes after TaTME versus cTME for rectal cancer. Methods TaTME was implemented in 2014 using IDEAL principles in a single institution. The institution maintains databases for all patients undergoing rectal cancer surgery. This retrospective review compared data collected from all patients who had TaTME with those from a propensity-matched cohort of patients who underwent cTME. The primary outcome was a composite pathological measure combining margin status and quality of total mesorectal excision (TME). Short-term clinical and survival outcomes were also measured. Results Propensity matching created 109 matched pairs for analysis. Nine patients (8.3 per cent) undergoing TaTME had positive margins and/or incomplete TME, compared with 11 (10.5 per cent) undergoing cTME (P = 0.65). There were no significant differences in morbidity between the TaTME and cTME groups, including number of anastomotic leaks (13.8 versus 18.3 per cent; P = 0.37). The estimated 3-year local recurrence-free survival rate was 96.3 per cent in both groups (P = 0.39). Estimated 3-year overall (93.6 per cent for TaTME versus 94.5 per cent for cTME; P = 0.09) and disease-free (88.1 versus 76.1 per cent; P = 0.90) survival rates were similar. Conclusion TaTME provided similar outcomes to cTME for rectal cancer with the application of IDEAL principles.

Abstract
Introduction: New medical devices must have adequate research, such that outcomes are known, enabling patients to be consented with knowledge of the safety and efficacy of the device to be implanted. Device trials are challenging due to the learning curve and iterative assessment of best practice. This study is designed to pilot a national collaborative approach to medical device introduction by breast surgeons in the UK, using breast localisation devices as an exemplar. The aim is to develop an effective and transferable surgical device platform protocol design, with embedded shared learning. Methods and analysis: The iBRA-net localisation study is a UK based prospective, multi-centre platform study, comparing the safety and efficacy of novel localisation devices with wire-guided breast lesion localisation for wide local excision, using Magseed® as the pilot intervention group. Centres performing breast lesion localisation for wide local excision or excision biopsy will be eligible to participate if using one of the included devices. Further intervention arms will be added as new devices are CE marked. Outcomes will be collected via an online database. The primary outcome measure will be identification of the index lesion. Participating surgeons will be asked to record shared learning events via online questionnaires and focus group interviews to inform future study arms. Ethics and dissemination: The study will aim to collect data on 950 procedures for each intervention (Magseed® and wire localisation) from UK breast centres over an 18-month period. Shared learning will be prospectively evaluated via thematic analysis to refine breast localisation technique and to promote early identification of potential pitfalls and problems. Results will be presented at national and international conferences and published in peer reviewed journals. Registration: This is a UK national audit registered with Manchester University NHS Foundation Trust. Highlights

Abstract
BACKGROUND Pilonidal sinus is a hole in the natal cleft which may cause severe pain and become infected. The evidence base for management of pilonidal sinus is said to be poor quality, poorly focused and rapidly proliferating. We undertook a systematic mapping review to provide a broad overview of the field and support the identification of research priorities. METHODS We searched MEDLINE, CINAHL, and EMBASE from inception to 22nd Nov 2020 for primary research studies focused on the management of pilonidal sinus. We extracted data on study design and categorised studies under five major headings ('non-surgical treatment', 'surgical treatment', 'aftercare' and 'other'), producing frequency counts for different study designs. Gaps in research were identified from published systematic reviews and tabulated. RESULTS We identified 983 eligible studies, of which 36 were systematic reviews and/or meta-analyses; 121 were randomised controlled trials), and 826 observational studies of various design. The majority of studies evaluated surgical techniques (n = 665), or adjuvant medical interventions (n = 98). The literature on wound care has developed most recently, and the evidence base includes 30% randomised controlled trials. Gaps analysis highlighted comparison of surgical techniques including flaps, laser depilation, and wound care interventions as potential areas for randomised controlled trials. CONCLUSIONS This mapping review summarises eight decades of research on the management of pilonidal sinus. Further research is needed to identify front-running interventions, understand variation in practice and patient values, and to prioritise future research.

Abstract
BACKGROUND The Idea, Development, Exploration, Assessment and Long-term study (IDEAL) framework was created to provide a structured way for assessing and evaluating novel surgical techniques and devices. OBJECTIVES The aim of this paper was to investigate the utilization of the IDEAL framework within neurosurgery, and to identify factors influencing implementation. METHODS A bibliometric analysis of the 7 key IDEAL papers on Scopus, PubMed, Embase, Web of Science, and Google Scholar databases (2009-2019) was performed. A second journal-specific search then identified additional papers citing the IDEAL framework. Publications identified were screened by two independent reviewers to select neurosurgery-specific articles. RESULTS The citation search identified 1336 articles. The journal search identified another 16 articles. Following deduplication and review, 51 relevant articles remained; 14 primary papers (27%) and 37 secondary papers (73%). Of the primary papers, 5 (36%) papers applied the IDEAL framework to their research correctly; two were aligned to the pre-IDEAL stage, one to the Idea and Development stages, and two to the Exploration stage. Of the secondary papers, 21 (57%) explicitly discussed the IDEAL framework. Eighteen (86%) of these were supportive of implementing the framework, while one was not, and two were neutral. CONCLUSION The adoption of the IDEAL framework in neurosurgery has been slow, particularly for early-stage neurosurgical techniques and inventions. However, the largely positive reviews in secondary literature suggest potential for increased use that may be achieved with education and publicity.

Abstract
Aims Slipped capital femoral epiphysis (SCFE) is one of the most common hip diseases of adolescence that can cause marked disability, yet there is little robust evidence to guide treatment. Fundamental aspects of the disease, such as frequency, are unknown and consequently the desire of clinicians to undertake robust intervention studies is somewhat prohibited by a lack of fundamental knowledge. Methods The study is an anonymized nationwide comprehensive cohort study with nested consented within the mechanism of the British Orthopaedic Surgery Surveillance (BOSS) Study. All relevant hospitals treating SCFE in England, Scotland, and Wales will contribute anonymized case details. Potential missing cases will be cross-checked against two independent external sources of data (the national administrative data and independent trainee data). Patients will be invited to enrich the data collected by supplementing anonymized case data with patient-reported outcome measures. In line with recommendations of the IDEAL Collaboration, the study will primarily seek to determine incidence, describe case mix and variations in surgical interventions, and explore the relationships between baseline factors (patients and types of interventions) and two-year outcomes. Discussion This is the first disease to be investigated using the BOSS Study infrastructure. It provides a robust method to determine the disease frequency, and a large unbiased sample of cases from which treatment strategies can be investigated. It may form the basis for definitive robust intervention studies or, where these are demonstrated not to be feasible, this may be the most robust cohort study.

Abstract
Introduction There is widespread variation in the management of rare orthopaedic disease, in a large part owing to uncertainty. No individual surgeon or hospital is typically equipped to amass sufficient numbers of cases to draw robust conclusions from the information available to them. The programme of research will establish the British Orthopaedic Surgery Surveillance (BOSS) Study; a nationwide reporting structure for rare disease in orthopaedic surgery. Methods The BOSS Study is a series of nationwide observational cohort studies of pre-specified orthopaedic disease. All relevant hospitals treating the disease are invited to contribute anonymised case details. Data will be collected digitally through REDCap, with an additional bespoke software solution used to regularly confirm case ascertainment, prompt follow-up reminders and identify potential missing cases from external sources of information (i.e. national administrative data). With their consent, patients will be invited to enrich the data collected by supplementing anonymised case data with patient reported outcomes. The study will primarily seek to calculate the incidence of the rare diseases under investigation, with 95% confidence intervals. Descriptive statistics will be used to describe the case mix, treatment variations and outcomes. Inferential statistical analysis may be used to analyze associations between presentation factors and outcomes. Types of analyses will be contingent on the disease under investigation. Discussion This study builds upon other national rare disease supporting structures, particularly those in obstetrics and paediatric surgery. It is particularly focused on addressing the evidence base for quality and safety of surgery, and the design is influenced by the specifications of the IDEAL collaboration for the development of surgical research.

Abstract
BACKGROUND Outcome selection, measurement and reporting for the evaluation of new surgical procedures and devices is inconsistent and lacks standardization. A core outcome set may promote the safe and transparent evaluation of surgical innovations. This systematic review examined outcome selection, measurement and reporting in studies conducted within the IDEAL (Idea, Development, Exploration, Assessment and Long-term monitoring) framework to examine current practice and inform the development of a core outcome set for early-phase studies of surgical procedures/devices. METHODS Web of Science and Scopus citation searches were performed to identify author-reported IDEAL/IDEAL-D studies for any surgical procedure/device. Outcomes were extracted verbatim, including contextual information regarding outcome selection and measurement. Outcomes were categorized to inform a conceptual framework of outcome domains relevant to evaluating innovation. RESULTS Some 48 studies were identified. Outcome selection, measurement and reporting varied widely across studies in different IDEAL stages. From 1737 outcomes extracted, 22 domains specific to evaluating innovation were conceptualized under seven broad categories: procedure completion success/failure; modifications; unanticipated events; surgeons' experiences; patients' experiences; resource use specific to the innovative procedure/device; and other innovation-specific outcomes. Most innovation-specific outcomes were measured and reported in only a small number of studies. CONCLUSION This review highlighted the need for guidance and standardization in outcome selection and reporting in the evaluation of new surgical procedures/devices. Novel outcome domains specific to innovation have been identified to establish a core outcome set for future evaluations of surgical innovations.

Abstract
BACKGROUNDS The optimal surgical strategy for the treatment of chronic pain after inguinal hernia repair is controversial and based on relatively weak evidence. The purpose of this study was to analyze pain-related functional impairment using a simplified clinical treatment algorithm for a standardized surgical treatment. The algorithm was predefined, and the indication to operate was based on strict criteria. METHODS This was a prospective, non-controlled, explorative study. The pain operation was either open triple neurectomy with total mesh removal or laparoscopic retroperitoneal triple neurectomy. A clinically relevant postoperative change was defined as ⩾25% change from the baseline level. Primary outcome was pain-related impairment of physical function using the Activity Assessment Scale. Secondary outcomes included Individual Patient-Reported Outcome Measures, Hospital Anxiety and Depression Scale, and PainDETECT Questionnaire. RESULTS A total of 240 patients were referred (2016-2019). Sixty-six patients were included for the analysis. A total of 25% of referred patients were offered a pain operation. Follow-up was a median 3 months (range: 3-13). Activity Assessment Scale scores were clinically relevant improved in 43 patients (68%), not clinically relevant different in 19 (30%), and clinically relevant worsened in one (2%). Secondary outcome scores were all significantly improved (P < 0.05) except for the risk of postoperative depression (P = 0.092). Fifty-one patients (77%) reported that chronic groin pain was reduced after the operation. CONCLUSIONS Pain-related functional impairment was improved with clinical relevance in roughly 70% of patients through a simplified clinical algorithm for surgical treatment of severe chronic pain after an inguinal hernia repair.

Abstract
Healing of fractures and bone defects normally follows an orderly series of events including formation of a hematoma and an initial stage of inflammation, development of soft callus, formation of hard callus, and finally the stage of bone remodeling. In cases of severe musculoskeletal injury due to trauma, infection, irradiation and other adverse stimuli, deficient healing may lead to delayed or non-union; this results in a residual bone defect with instability, pain and loss of function. Modern methods of mechanical stabilization and autologous bone grafting are often successful in achieving fracture union and healing of bone defects; however, in some cases, this treatment is unsuccessful because of inadequate biological factors. Specifically, the systemic and local microenvironment may not be conducive to bone healing because of a loss of the progenitor cell population for bone and vascular lineage cells. Autologous bone grafting can provide the necessary scaffold, progenitor and differentiated lineage cells, and biological cues for bone reconstruction, however, autologous bone graft may be limited in quantity or quality. These unfavorable circumstances are magnified in systemic conditions with chronic inflammation, including obesity, diabetes, chronic renal disease, aging and others. Recently, strategies have been devised to both mitigate the necessity for, and complications from, open procedures for harvesting of autologous bone by using minimally invasive aspiration techniques and concentration of iliac crest bone cells, followed by local injection into the defect site. More elaborate strategies (not yet approved by the U.S. Food and Drug Administration-FDA) include isolation and expansion of subpopulations of the harvested cells, preconditioning of these cells or inserting specific genes to modulate or facilitate bone healing. We review the literature pertinent to the subject of modifying autologous harvested cells including MSCs to facilitate bone healing. Although many of these techniques and technologies are still in the preclinical stage and not yet approved for use in humans by the FDA, novel approaches to accelerate bone healing by modifying cells has great potential to mitigate the physical, economic and social burden of non-healing fractures and bone defects.

Development of sentinel lymph node biopsy technique in patients with salivary gland cancer using the IDEAL framework. Eur J Surg Oncol 2020; 46:2029-2034. [PMID: 32576478 DOI: 10.1016/j.ejso.2020.05.015] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 04/26/2020] [Accepted: 05/14/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Salivary cancer is rare and comprises a variety of histological subtypes and clinical behaviors. There is no agreed method of estimating the risk of occult metastasis or managing the clinically N0 neck.Sentinel node biopsy (SNB) may offer a solution but previous studies have not produced a reliable imaging protocol. This study uses novel technology and trial methodology to develop a reliable SNB technique, with primary aim to identify peri-and intraglandular sentinel nodes. METHODS IDEAL framework was used to undertake SNB in clinically node negative salivary gland cancer. Patients with cT1-2 N0 salivary cancer were eligible. Lymphoscintigraphy was undertaken using Tc-99 m labelled nanocoll. Injection technique as well as adjunctive use of freehand SPECT (fhSPECT), near-infrared (NIR) fluorescence imaging, and navigation-guided surgery were used and optimisied during the study protocol. RESULTS 10 patients were recruited. Initial protocol of peritumoural injection of Tc99 m nanocoll showed poor image resolution. Subsequent adjustment to single intratumoural injection allowed identification of intraglandular sentinel nodes. Fh/SPECT and NIR fluorescence imaging found intraglandular lymph nodes otherwise not recognizable to the naked eye. In two cases occult lymph node metastasis were identified. CONCLUSION This study has shown the IDEAL framework is vital in allowing iterative changes in surgical protocol in the light of experience. This study has produced a reliable method for detection of sentinel nodes, in particular the ability to identify intra- and periglandular nodes with diagnosis of occult metastatic deposits and no false negative results. Our protocol can be readily transferred in to larger scale studies.

Abstract
PURPOSE The aim of this study was to examine the external validity of the randomized TIME trial, when minimally invasive esophagectomy (MIE) was implemented nationally in the Netherlands, using data from the Dutch Upper GI Cancer Audit (DUCA) for transthoracic esophagectomy. METHODS Original patient data from the TIME trial were extracted along with data from the DUCA dataset (2011-2017). Multivariate analysis, with adjustment for patient factors, tumor factors, and year of surgery, was performed for the effect of MIE versus open esophagectomy on clinical outcomes. RESULTS One hundred fifteen patients from the TIME trial (59 MIE v 56 open) and 4,605 patients from the DUCA dataset (2,652 MIE v 1,953 open) were included. In the TIME trial, univariate analysis showed that MIE reduced pulmonary complications and length of hospital stay. On the contrary, in the DUCA dataset, MIE was associated with increased total and pulmonary complications and reoperations; however, benefits included increased proportion of R0 margin and lymph nodes harvested, and reduced 30-day mortality. Multivariate analysis from the TIME trial showed that MIE reduced pulmonary complications (odds ratio [OR], 0.19; 95% CI, 0.06 to 0.61). In the DUCA dataset, MIE was associated with increased total complications (OR, 1.36; 95% CI, 1.19 to 1.57), pulmonary complications (OR, 1.50; 95% CI, 1.29 to 1.74), reoperations (OR, 1.74; 95% CI, 1.42 to 2.14), and length of hospital stay. Multivariate analysis of the combined and MIE datasets showed that inclusion in the TIME trial was associated with a reduction in reoperations, Clavien-Dindo grade > 1 complications, and length of hospital stay. CONCLUSION When adopted nationally outside the TIME trial, MIE was associated with an increase in total and pulmonary complications and reoperation rate. This may reflect nonexpert surgeons outside of high-volume centers performing this minimally invasive technique in a nonstandardized fashion outside of a controlled environment.

Abstract
Objective: Analysis of treatment success regarding oncological recurrence rate between standard and dose escalation focal high-intensity focused ultrasound (HIFU) of prostate cancer. Materials and Methods: In this analysis of our prospectively maintained HIFU (Sonablate® 500) database, 598 patients were identified who underwent a focal HIFU (Sonablate 500) between March 2007 and November 2016. Follow-up occurred with 3-monthly clinic visits and prostate specific antigen (PSA) testing in the first year. Thereafter, PSA was measured 6-monthly or annually at least. Routine and for-cause multiparametric MRI (mpMRI) was conducted with biopsy for MRI suspicion of recurrence. Treatments were delivered in a quadrant or hemiablation fashion depending on the gland volume as well as tumor volume and location. Before mid-2015, standard focal HIFU was used (two HIFU blocks); after this date, some urologists conducted dose escalation focal HIFU (three overlapping HIFU blocks). Propensity matching was used to ensure two matched groups, leading to 162 cases for this analysis. Treatment failure was defined by any secondary treatment (systemic therapy, cryotherapy, radiotherapy, prostatectomy, or further HIFU), metastasis from prostate cancer without further treatment, tumor recurrence with Gleason score ≥7 (≥3 + 4) on prostate biopsy without further treatment, or prostate cancer-related mortality. Complications and side-effects were also compared. Results: Median age was 64.5 years (interquartile range [IQR] 60-73.5) in the standard focal-HIFU group and 64.5 years (IQR 60-69) in the dose-escalation group. Median prostate volume was 37 mL (IQR 17-103) in the standard group and 47.5 mL (IQR 19-121) in the dose-escalation group. As tumor volume on mpMRI and Gleason score were major matching criteria, these were identical with 0.43 mL (IQR 0.05-2.5) and Gleason 3 + 3 = 6 in 1 out of 32 (3%), 3 + 4 = 7 in 27 out of 32 (84%), and 4 + 3 = 7 in 4 out of 32 (13%). Recurrence in treated areas was found in 10 out of 32 (31%) when standard treatment zones were applied, and in 6 out of 32 (19%) of dose-escalation focal HIFU (p = 0.007). Conclusion: This exploratory study shows that dose escalation focal HIFU may achieve higher rates of disease control compared with standard focal HIFU. Further prospective comparative studies are needed.

Abstract
BACKGROUND Randomized controlled trial (RCT) testing surgical intervention faced challenges due to complexities of surgery and made it more difficult for surgeons and methodologists than pharmaceutical providers to build a well-design, conduct RCT. OBJECTIVE We conducted a cross-sectional survey to address the methodological challenges of RCTs on surgical intervention and offer potential solutions. METHODS We searched PubMed in order to summarize 2-arm parallel randomized trials for surgical interventions published in 2013. The information regarding general characteristics, general methodological and special surgical characteristics related to surgical trials comparing alternative procedures was gathered. RESULTS Some 200 surgical trials were identified. The extent to which these trials in design, conduct and analysis differed substantially across items. The general information about sample size calculation (77.0%), lost to follow-up (71.5%), trial registration (55.5%), protocols of trials (56.0%), implementation of randomization (59.5%), concealment of randomization (56.0%); reporting of primary outcome as P value (67.0%). Surgery special information revealed that only 21.0% of trials considered surgeons' preference, approximately 12% to 50% of them controlled the quality of surgical interventions and none evaluated the effect of the learning curve. CONCLUSION There is much room for improvement concerning the reported designs, conduct, and analysis of surgical RCTs. Considering the difficulty of surgical RCTs, some other approaches, such as surgeons' eligibility, performance of pilot studies, or implementation of pragmatic RCTs/expertise-based trials, should be feasibly implemented to overcome the presented challenges.

Quantitative anatomical comparison of transnasal and transcranial approaches to the clivus. Acta Neurochir (Wien) 2020; 162:649-660.

Abstract
BACKGROUND AND OBJECTIVE The clivus was defined as "no man's land" in the early 1990s, but since then, multiple approaches have been described to access it. This study is aimed at quantitatively comparing endoscopic transnasal and microsurgical transcranial approaches to the clivus in a preclinical setting, using a recently developed research method. METHODS Multiple approaches were performed in 5 head and neck specimens that underwent high-resolution computed tomography (CT): endoscopic transnasal (transclival, with hypophysiopexy and with far-medial extension), microsurgical anterolateral (supraorbital, mini-pterional, pterional, pterional transzygomatic, fronto-temporal-orbito-zygomatic), lateral (subtemporal and subtemporal transzygomatic), and posterolateral (retrosigmoid, far-lateral, retrolabyrinthine, translabyrinthine, and transcochlear). An optic neuronavigation system and dedicated software were used to quantify the working volume of each approach and calculate the exposure of different clival regions. Mixed linear models with random intersections were used for statistical analyses. RESULTS Endoscopic transnasal approaches showed higher working volume and larger exposure compared with microsurgical transcranial approaches. Increased exposure of the upper clivus was achieved by the transnasal endoscopic transclival approach with intradural hypophysiopexy. Anterolateral microsurgical transcranial approaches provided a direct route to the anterior surface of the posterior clinoid process. The transnasal endoscopic approach with far-medial extension ensured a statistically larger exposure of jugular tubercles as compared with other approaches. Presigmoid approaches provided a relatively limited exposure of the ipsilateral clivus, which increased in proportion to their invasiveness. CONCLUSIONS This is the first anatomical study that quantitatively compares in a holistic way exposure and working volumes offered by the most used modern approaches to the clivus.
