Abstract
BACKGROUND Robotic radical prostatectomy (RARP) is a first-line curative treatment option for localized prostate cancer. Postoperative erectile dysfunction and urinary incontinence are common associated adverse side effects that can negatively impact patients' quality of life. Preserving the lateral neurovascular bundles (NS) during RARP improves functional outcomes. However, selecting men for NS may be difficult when there is concern about incurring in positive surgical margin (PSM) which in turn risks adverse oncological outcomes. The NeuroSAFE technique (intra-operative frozen section examination of the neurovascular structure adjacent prostate margin) can provide real-time pathological consult to promote optimal NS whilst avoiding PSM. METHODS NeuroSAFE PROOF is a single-blinded, multi-centre, randomised controlled trial (RCT) in which men are randomly allocated 1:1 to either NeuroSAFE RARP or standard RARP. Men electing for RARP as primary treatment, who are continent and have good baseline erectile function (EF), defined by International Index of Erectile Function (IIEF-5) score > 21, are eligible. NS in the intervention arm is guided by the NeuroSAFE technique. NS in the standard arm is based on standard of care, i.e. a pre-operative image-based planning meeting, patient-specific clinical information, and digital rectal examination. The primary outcome is assessment of EF at 12 months. The primary endpoint is the proportion of men who achieve IIEF-5 score ≥ 21. A sample size of 404 was calculated to give a power of 90% to detect a difference of 14% between groups based on a feasibility study. Oncological outcomes are continuously monitored by an independent Data Monitoring Committee. Key secondary outcomes include urinary continence at 3 months assessed by the international consultation on incontinence questionnaire, rate of biochemical recurrence, EF recovery at 24 months, and difference in quality of life. DISCUSSION NeuroSAFE PROOF is the first RCT of intra-operative frozen section during radical prostatectomy in the world. It is properly powered to evaluate a difference in the recovery of EF for men undergoing RARP assessed by patient-reported outcome measures. It will provide evidence to guide the use of the NeuroSAFE technique around the world. TRIAL REGISTRATION NCT03317990 (23 October 2017). Regional Ethics Committee; reference 17/LO/1978.

Early evaluation of a next-generation surgical system in robot-assisted total laparoscopic hysterectomy: A prospective clinical cohort study. Acta Obstet Gynecol Scand 2022; 101:978-986. [PMID: 35861102 DOI: 10.1111/aogs.14407] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 05/06/2022] [Accepted: 06/06/2022] [Indexed: 01/03/2023]
Abstract
INTRODUCTION This study aimed to demonstrate the safe and effective use of the Versius surgical system (CMR Surgical, Cambridge, UK) in robot-assisted total laparoscopic hysterectomy. This surgical robot was developed iteratively with input from surgeons to improve surgical outcomes and end-user experience. We report data from the gynecology cohort of an early clinical trial designed in broad alignment with IDEAL-D (Idea, Development, Exploration, Assessment, Long-term follow-up - Devices) stage 2b (Exploration). MATERIAL AND METHODS The study is registered in the Indian clinical trials register (CTRI/2019/02/017872). Adult women requiring total hysterectomy who provided informed consent and met the eligibility criteria underwent procedures at one of three hospitals in India. Five surgeons performed robot-assisted total laparoscopic hysterectomies using the device from March 2019 to September 2020. The primary endpoint was rate of unplanned conversion to conventional laparoscopic or open surgery. Adverse events were adjudicated by an independent clinical events committee using endoscope video recordings and clinical notes. RESULTS In total, 144 women underwent surgery (median age: 44 years [range: 28-78]; median body mass index 25.8 kg/m2 [range: 14.3-47.8]). The rate of unplanned conversion to conventional laparoscopy was 2/144 (1.4%); neither conversion was device related. No surgery was converted to open. In total, 13 adverse events occurred among seven (4.9%) patients, comprising seven serious adverse events and six adverse events. One serious adverse event was deemed device-related. Two patients were readmitted to hospital within 30 days; both made a full recovery. No patients died within 90 days of surgery. CONCLUSIONS The device provides a safe and effective option for total laparoscopic hysterectomy; these findings support its continued implementation in larger patient cohorts and expansion in other major minimal access indications.

Abstract
Kidney transplantation (KT) is the treatment of choice for patients with end-stage renal disease, providing a better survival rate and quality of life compared to dialysis. Despite the progress in the medical management of KT patients, from a purely surgical standpoint, KT has resisted innovations during the last 50 years. Recently, robot-assisted KT (RAKT) has been proposed as an alternative approach to open surgery, especially due to its potential benefits for fragile and immunocompromised recipients. It was not until 2014 that the role of RAKT has found value thanks to the pioneering Vattikuti Urology Institute-Medanta collaboration that conceptualized and developed a new surgical technique for RAKT following the Idea, Development, Exploration, Assessment, Long-term follow-up recommendations for introducing surgical innovations into real-life practice. During the last years, mirroring the Vattikuti-Medanta technique, several centers developed RAKT program worldwide, providing strong evidence about the safety and the feasibility of this procedure. However, the majority of RAKT are still performed in the living donor setting, as an “eligible” procedure, while only a few centers have realized KT through a robotic approach in the challenging scenario of cadaver donation. In addition, despite the spread of minimally-invasive (predominantly robotic) surgery worldwide, many KTs are still performed in an open fashion. Regardless of the type of incision employed by surgeons, open KT may lead to non-negligible risks of wound complications, especially among obese patients. Particularly, the assessment for KT should consider not only the added surgical technical challenges but also the higher risk of postoperative complications. In this context, robotic surgery could offer several benefits, including providing a better exposure of the surgical field and better instrument maneuverability, as well as the possibility to integrate other technological nuances, such as the use of intraoperative fluorescence vascular imaging with indocyanine green to assess the ureteral vascularization before the uretero-vesical anastomosis. Therefore, our review aims to report the more significant experiences regarding RAKT, focusing on the results and future perspectives.

How to assess applicability and methodological quality of comparative studies of operative interventions in orthopedic trauma surgery. Eur J Trauma Emerg Surg 2022; 48:4943-4953. [PMID: 35809102 DOI: 10.1007/s00068-022-02031-9] [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: 03/15/2022] [Accepted: 06/05/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE It is challenging to generate and subsequently implement high-quality evidence in surgical practice. A first step would be to grade the strengths and weaknesses of surgical evidence and appraise risk of bias and applicability. Here, we described items that are common to different risk-of-bias tools. We explained how these could be used to assess comparative operative intervention studies in orthopedic trauma surgery, and how these relate to applicability of results. METHODS We extracted information from the Cochrane risk-of-bias-2 (RoB-2) tool, Risk Of Bias In Non-randomised Studies-of Interventions tool (ROBINS-I), and Methodological Index for Non-Randomized Studies (MINORS) criteria and derived a concisely formulated set of items with signaling questions tailored to operative interventions in orthopedic trauma surgery. RESULTS The established set contained nine items: population, intervention, comparator, outcome, confounding, missing data and selection bias, intervention status, outcome assessment, and pre-specification of analysis. Each item can be assessed using signaling questions and was explained using good practice examples of operative intervention studies in orthopedic trauma surgery. CONCLUSION The set of items will be useful to form a first judgment on studies, for example when including them in a systematic review. Existing risk of bias tools can be used for further evaluation of methodological quality. Additionally, the proposed set of items and signaling questions might be a helpful starting point for peer reviewers and clinical readers.

Abstract
OBJECTIVE To identify, categorize, and evaluate the quality of literature, and to provide evidence-based guidelines on virtual surgical education within the cognitive and curricula, psychomotor, and faculty development and mentorship domains. SUMMARY OF BACKGROUND DATA During the coronavirus disease 2019 pandemic, utilizing virtual learning modalities is expanding rapidly. Although the innovative methods must be considered to bridge the surgical education gap, a framework is needed to avoid expansion of virtual education without proper supporting evidence in some areas. METHODS The Association for Surgical Education formed an ad-hoc research group to evaluate the quality and methodology of the current literature on virtual education and to build evidence-based guidelines by utilizing the SiGN methodology. We identified patient/problem-intervention-comparison-outcome-style questions, conducted systematic literature reviews using PubMed, EMBASE, and Education Resources information Center databases. Then we formulated evidence-based recommendations, assessed the quality of evidence using Grading of Recommendations, Assessment, Development, and Evaluation, Newcastle-Ottawa Scale for Education, and Kirkpatrick ratings, and conducted Delphi consensus to validate the recommendations. RESULTS Eleven patient/problem-intervention-comparison-outcome-style questions were designed by the expert committees. After screening 4723 articles by the review committee, 241 articles met inclusion criteria for full article reviews, and 166 studies were included and categorized into 3 domains: cognition and curricula (n = 92), psychomotor, (n = 119), and faculty development and mentorship (n = 119). Sixteen evidence-based recommendations were formulated and validated by an external expert panel. CONCLUSION The evidence-based guidelines developed using SiGN methodology, provide a set of recommendations for surgical training societies, training programs, and educators on utilizing virtual surgical education and highlights the area of needs for further investigation.

Abstract
OBJECTIVE To identify implantable devices currently used for vascular and endovascular procedures, to ascertain how many have randomised controlled trial (RCT) evidence available, and to assess the quality of that evidence. DATA SOURCES MEDLINE, Embase, DARE, PROSPERO, clinical trial registries, and Cochrane databases. REVIEW METHODS A list of current devices used in both vascular and endovascular procedures was generated by searching conference proceedings, manufacturer catalogues, and websites. MEDLINE, Embase, DARE, PROSPERO, clinical trial registries, and Cochrane databases were searched from inception up to June 2020. The primary outcome was the availability of RCTs to support the use of a vascular implantable device. RCTs were then quality assessed using the Cochrane risk of bias tool. RESULTS A total of 116 current vascular implantable devices were identified. The systematic literature review identified 165 RCTs. Eighty-three of the RCTs (50.3%) applied to 33 of the 116 (28.4%) current implantable devices. When grouped by device type, eight of the 13 types (62%) had at least one RCT performed. There was a high risk of bias across the majority of the RCTs, with only nine (5.4%) deemed to be at low risk of bias. Only 22 (13.3%) RCTs had a clear safety outcome. CONCLUSION Sixty-two per cent of implantable device types for use in vascular and endovascular interventions had at least one RCT available to show equivalence to previous devices or safety. RCTs were generally of low quality and are decreasing in frequency with time. With medical implantable device failure being increasingly recognised as causing significant harm to patients worldwide, there is a clear need for a more robust implantable device regulation and approval systems.

Abstract
ObjectiveTo assess the impact of iterative changes in preoperative and postoperative biopsy techniques on the outcomes of men undergoing the precision prostatectomy procedure. Precision prostatectomy is a novel surgical treatment for prostate cancer that aims to maximally preserve erectogenic nerves via partial preservation of the prostate capsule.DesignRetrospective.SettingSingle tertiary care center.ParticipantsThis study included 120 patients who consented to undergo prostate cancer treatment with the precision prostatectomy procedure. Patients were originally enrolled in one of two separate prospective protocols studying precision prostatectomy.InterventionsPreoperatively, 60 patients were screened with transrectal (TR) biopsy and 60 were screened by transperineal (TP) biopsy. Ultimately, 117 patients underwent precision prostatectomy. Of the 43 postoperative biopsies, 19 were TR; 17 were TP with ultrasound; and 7 were TP with microultrasound (mUS).Main outcome measuresPreoperatively, we evaluated whether the transition to TP biopsy was associated with differences in postoperative treatment failure defined as a neoplasm-positive postoperative biopsy. Postoperative biopsies were compared with respect to their ability to sample the remnant tissue, specifically percentage of cores positive for prostate tissue.ResultsPreoperatively, 9/60 (15%) positive postoperative biopsies occurred in the TR group and 6/60 (10%) in the TP group; Kaplan-Meier survival estimates did not differ between groups (p=0.69 by log rank). Postoperatively, the numbers of cores positive for prostate tissue were 99/160 (62%), 63/107 (59%), and 36/39 (92%) in the TR biopsy, TP with ultrasound, and TP with mUS groups, respectively; this difference was statistically significant versus the rate in the TR and standard TP groups (p=0.0003 and 0.0002).ConclusionWe found no significant improvement in patient screening, preoperatively—though limited by small sample size and relatively short follow-up. The incorporation of high-frequency mUS for postoperative biopsies improved the ability to sample the remnant tissue with a higher efficiency.

Abstract
BACKGROUND The mainstay of treatment for venous ulceration is conservative wound management and lifelong compression therapy. For patients with recalcitrant ulcers, free flap reconstruction has been proposed as a treatment option to reconstruct the diseased soft tissues as well as the underlying insufficient venous system. This review systematically evaluates the outcomes of free flap reconstruction for chronic venous ulcers in the lower limb. METHOD A protocol was developed a priori and registered on the PROSPERO database. A systematic search of literature was performed in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), clinical trials registries, and OpenGrey from inception to April 2020 according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies of patients undergoing free tissue transfer reconstruction for chronic venous ulcers in the lower limb were included. RESULTS A total of 5 noncomparative cohort studies featuring 56 patients with 62 recalcitrant venous ulcers treated with 64 free flaps who had a mean age of 50 years (range, 17-76 years) were included, and a narrative analysis undertaken. Mean defect size following ulcer debridement was 153.3 cm2 (range, 24-600 cm2). Defects were reconstructed with muscle (n = 39 [60.9%]), fasciocutaneous (n = 23 [35.9%]), and visceral (n = 2 [3.1%]) free flaps, with latissimus dorsi (n = 16, 25%) and rectus abdominis flaps (n = 16, 25%) being the most frequently used. Mean follow-up ranged from 24 to 125 months. Pooled flap survival rate was 95%. No recurrence within the territory of the flap was reported, but there were 20 instances (35.7%) of new ulcers outside of the flap boundaries. CONCLUSION There is currently an absence of evidence to support the use of free flap reconstruction for recalcitrant venous ulcers compared with conventional management. Although evidence suggests that it is technically feasible, there is no evidence to suggest it prevents ulceration outside the reconstructed region. Further studies are necessary to evaluate its effectiveness for venous ulcers in the lower limb.

Front Surg 2022; 9:920252. [PMID: 35903256 PMCID: PMC9316615 DOI: 10.3389/fsurg.2022.920252] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 05/12/2022] [Indexed: 11/28/2022] Open
Abstract
Background An exoscope heralds a new era of optics in surgery. However, there is limited quantitative evidence describing and comparing the learning curve. Objectives This study aimed to investigate the learning curve, plateau, and rate of novice surgeons using an Olympus ORBEYE exoscope compared to an operating microscope (Carl Zeiss OPMI PENTERO or KINEVO 900). Methods A preclinical, randomized, crossover, noninferiority trial assessed the performance of seventeen novice and seven expert surgeons completing the microsurgical grape dissection task “Star’s the limit.” A standardized star was drawn on a grape using a stencil with a 5 mm edge length. Participants cut the star and peeled the star-shaped skin off the grape with microscissors and forceps while minimizing damage to the grape flesh. Participants repeated the task 20 times consecutively for each optical device. Learning was assessed using model functions such as the Weibull function, and the cognitive workload was assessed with the NASA Task Load Index (NASA-TLX). Results Seventeen novice (male:female 12:5; median years of training 0.4 [0–2.8 years]) and six expert (male:female 4:2; median years of training 10 [8.9–24 years]) surgeons were recruited. “Star’s the limit” was validated using a performance score that gave a threshold of expert performance of 70 (0–100). The learning rate (ORBEYE −0.94 ± 0.37; microscope −1.30 ± 0.46) and learning plateau (ORBEYE 64.89 ± 8.81; microscope 65.93 ± 9.44) of the ORBEYE were significantly noninferior compared to those of the microscope group (p = 0.009; p = 0.027, respectively). The cognitive workload on NASA-TLX was higher for the ORBEYE. Novices preferred the freedom of movement and ergonomics of the ORBEYE but preferred the visualization of the microscope. Conclusions This is the first study to quantify the ORBEYE learning curve and the first randomized controlled trial to compare the ORBEYE learning curve to that of the microscope. The plateau performance and learning rate of the ORBEYE are significantly noninferior to those of the microscope in a preclinical grape dissection task. This study also supports the ergonomics of the ORBEYE as reported in preliminary observational studies and highlights visualization as a focus for further development.

Abstract
Imaging of blood vessel structure in combination with functional information about blood oxygenation can be important in characterizing many different health conditions in which the growth of new vessels contributes to the overall condition. In this paper, we present a method for extracting comprehensive maps of the vasculature from hyperspectral images that include tissue and vascular oxygenation. We also show results from a preclinical study of peritonitis in mice. First, we analyze hyperspectral images using Beer-Lambert exponential attenuation law to obtain maps of hemoglobin species throughout the sample. We then use an automatic segmentation algorithm to extract blood vessels from the hemoglobin map and combine them into a vascular structure-oxygenation map. We apply this methodology to a series of hyperspectral images of the abdominal wall of mice with and without induced peritonitis. Peritonitis is an inflammation of peritoneum that leads, if untreated, to complications such as peritoneal sclerosis and even death. Characteristic inflammatory response can also be accompanied by changes in vasculature, such as neoangiogenesis. We demonstrate a potential application of the proposed segmentation and processing method by introducing an abnormal tissue fraction metric that quantifies the amount of tissue that deviates from the average values of healthy controls. It is shown that the proposed metric successfully discriminates between healthy control subjects and model subjects with induced peritonitis and has a high statistical significance.

Abstract
BACKGROUND Surgical safety and patient-related outcomes are important considerations when introducing new surgical techniques. Studies about the learning curves for different surgical procedures are sparse. The aim of this observational study was to evaluate the learning curve for ultrasonic fundus-first (FF) dissection in elective laparoscopic cholecystectomy (LC). METHODS The study was conducted at eight hospitals in Sweden between 2017 and 2019. The primary endpoint was dissection time, with secondary endpoints being intra- and postoperative complication rates and the surgeon's self-assessed performance level. Participating surgeons (n = 16) were residents or specialists who performed LC individually but who had no previous experience in ultrasonic FF dissection. Each surgeon performed fifteen procedures. Video recordings from five of the procedures were analysed by two external surgeons. Patient characteristics and data on complications were retrieved from the Swedish Registry of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks). RESULTS Dissection time decreased as experience increased (p = 0.001). Surgeons with limited experience showed more rapid progress. The overall complication rate was 14 (5.8%), including 3 (1.3%) potentially technique-related complications. Video assessment scores showed no correlation with the number of procedures performed. The self-assessed performance level was rated lower when the operation was more complicated (p < 0.001). CONCLUSIONS Our results show that dissection time decreased with increasing experience. Most surgeons identified both favourable and unfavourable aspects of the ultrasonic FF technique. The ultrasonic device is considered well suited for gallbladder surgery, but most participating surgeons preferred to dissect the gallbladder the traditional way, beginning in the triangle of Calot. Nevertheless, LC with ultrasonic FF dissection can be considered easy to learn with a low complication rate during the initial learning curve, for both residents and specialists.

A Preliminary Analysis of a Modified Anterior Approach to Hip Pericapsular Neurolysis for Inoperable Hip Fracture Using the IDEAL Framework. Healthcare (Basel) 2022; 10:healthcare10061002. [PMID: 35742053 PMCID: PMC9222877 DOI: 10.3390/healthcare10061002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 05/09/2022] [Accepted: 05/23/2022] [Indexed: 11/21/2022] Open
Abstract
Introduction: With an increasingly ageing population, there is a growing impact of fragility hip fracture on the healthcare system and on society as a whole. Oral and injectable analgesics are often insufficient whilst traction and regional blocks do not allow patients to be discharged easily. While the conventional approach of ultrasound-guided anterior hip pericapsular neurolysis can help a lot of inoperable hip fracture patients to relieve their fracture pain and facilitate subsequent nursing care, enormous technical challenges are encountered in some cases. In this retrospective case study, we evaluated the overall pain and functional outcomes of our modified approach of anterior hip pericapsular neurolysis for inoperable hip fractures using the IDEAL framework. Method: This retrospective case series studied patients with acute inoperable hip fracture who received the modified approach of anterior hip pericapsular neurolysis from January 2018 to June 2019 according to the IDEAL recommendations. The modified approach consisted of pericapsular nerve group (PENG) injection, iliopsoas plane infiltration, and the sagittal approach of obturator nerve articular branches (ONAB) injection. Subsequent alcohol neurolysis would be performed in the same setting if there were positive diagnostic blocks. Assessments were carried out on post-intervention day 5. The primary outcome was pain intensity during hip flexion at 80 degrees in the recumbent position and during gentle hip internal and external rotation using an appropriate pain scoring tool. The secondary outcomes were the range of tolerable hip flexion and occurrence of any lower limb neurological deficit because of the procedure. Interim outcomes were also briefly evaluated. Results: Among the 74 patients who were reviewed in the study period, the median dynamic pain at hip flexion 80° (p < 0.001) and on gentle hip external and internal rotation (p < 0.001) was significantly reduced from a composite score of 3 (severe pain) to 1 (mild pain) on post-intervention day 5 after the modified approach of hip neurolysis. This translated to 72% of patients achieving satisfactory pain control, which was defined as a composite pain score of ≤1 on hip flexion at 80°. Functionally, the mean range of tolerable hip flexion significantly improved from 39.7° at baseline to 74° on post-intervention day 5 (p < 0.001). Transient and reversible hypotension was seen in about 10% of the patients. No other major procedural adverse event was noted. Interim follow-up at 4−6 months post-intervention revealed that more than 95% of patients continued to have satisfactory dynamic pain control (i.e., composite pain score ≤ 1). According to the IDEAL classification, this study could be ranked as stage 2a (development). Conclusions: Our findings suggested that anterior hip pericapsular neurolysis using a modified approach could offer consistent and satisfactory analgesic and functional benefits to a majority of patients with inoperable hip fractures during the interim of the fracture healing process, and it was potentially safer than the conventional approach. This technique might have achieved its readiness to proceed to the next stage of research according to the IDEAL framework.

Abstract
Magnetic resonance imaging (MRI) has a key role to play at multiple steps of the radiotherapy (RT) treatment planning and delivery process. Development of high-precision RT techniques such as intensity-modulated RT, stereotactic ablative RT, and particle beam therapy has enabled oncologists to escalate RT dose to the target while restricting doses to organs at risk (OAR). MRI plays a critical role in target volume delineation in various disease sites, thus ensuring that these high-precision techniques can be safely implemented. Accurate identification of gross disease has also enabled selective dose escalation as a means to widen the therapeutic index. Morphological and functional MRI sequences have also facilitated an understanding of temporal changes in target volumes and OAR during a course of RT, allowing for midtreatment volumetric and biological adaptation. The latest advancement in linear accelerator technology has led to the incorporation of an MRI scanner in the treatment unit. MRI-guided RT provides the opportunity for MRI-only workflow along with online adaptation for either target or OAR or both. MRI plays a key role in post-treatment response evaluation and is an important tool for guiding decision making. In this review, we briefly discuss the RT-related applications of MRI in the management of brain, prostate, and GI malignancies.

Abstract
INTRODUCTION Early Feasibility Studies (EFS) are among the pre-market clinical investigations allowed by the International Standard for Clinical investigation of medical devices (MD) for human subjects. The Food and Drug Administration (FDA) introduced an EFS program in the US in 2013. The European Union (EU) MD Regulation, that entered into force in May 2021, opened the possibility of EFS in the EU. However, European countries at present have no standardized procedural framework for EFS. In this paper, we address the desirability of a European EFS program. AREAS COVERED Characteristics of EFS conducted so far are reviewed, and perceptions of an expert, multidisciplinary panel of key stakeholders are explored regarding desirability and feasibility of a European EFS program and critical factors favoring or hampering its implementation. EXPERT OPINION Implementing an EFS program in the EU would contribute to creating a favorable environment for early-stage clinical investigations, with positive effects on the quality and timeliness of clinical evidence for novel MDs, and attractiveness of the European system for pre- and post-market clinical research. Based on discussion with experts, also leveraging on the US experience, three dimensions should be considered for effective design and implementation: process, resources, and ethical issues.

Abstract
Plans to attempt what has been called a head transplant, a body transplant, and a head-to-body transplant in human beings raise numerous ethical, social, and legal questions, including the circumstances, if any, under which it would be ethically permissible to attempt whole-body transplantation (WBT) in human beings, the possible effect of WBT on family relationships, and how families should shape WBT decisions. Our assessment of many of these questions depends partially on how we respond to sometimes centuries-old philosophical thought experiments about personal identity. As with so much in bioethics, it is impossible to escape, or at least inadvisable to try to bypass, the relevant foundational philosophical concerns.

Abstract
Background: Donor hepatitis-C (HCV) infection has historically represented a barrier to kidney transplantation (KT). However, direct-acting antiviral (DAA) medications have revolutionised treatment of chronic HCV infection. Recent American studies have demonstrated that DAA regimes can be used safely peri-operatively in KT to mitigate HCV transmission risk. Methods: To formulate this narrative review, a comprehensive literature search was performed to analyse results of existing clinical trials examining KT from HCV-positive donors to HCV-negative recipients with peri-operative DAA regimes. Results: 13 studies were reviewed (11 single centre, four retrospective). Outcomes for 315 recipients were available across these studies. A sustained virological response at 12 weeks (SVR12) of 100% was achieved in 11 studies. One study employed an ultra-short DAA regime and achieved an SVR12 of 98%, while another achieved SVR12 of 96% due to treatment of a missed mixed genotype. Conclusion: HCV+ KT is safe and may allow increased utilisation of organs for transplantation from HCV+ donors, who often have other favourable characteristics for successful donation. Findings from US clinical trials can be applied to the United Kingdom transplant framework to improve organ utilisation as suggested by the NHSBT vision strategy "Organ Donation and Transplantation 2030: meeting the need".

Evolution of associating liver partition and portal vein ligation for staged hepatectomy from 2012 to 2021: A bibliometric analysis. Review. Int J Surg 2022; 103:106648. [PMID: 35513249 DOI: 10.1016/j.ijsu.2022.106648] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 04/15/2022] [Accepted: 04/19/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has become increasingly popular during the past few decades, and its indications have extended from patients with normal liver to post-chemotherapy patients and even patients with cirrhosis. However, few studies have assessed the publications in relation to ALPPS. METHODS Web of Science was searched to identify studies related to ALPPS published from 2012 to 2021. The analysis was performed using the bibliometric package (Version 3.1.0) in R software. RESULTS In total, 486 publications were found. These articles were published in 159 journals and authored by 2157 researchers from 694 organizations. The most prolific journal was Annals of Surgery (24 articles and 1170 citations). The most frequently cited article was published in Annals of Surgery (average citations, 72.7; total citations, 727). China was the most productive country for ALPPS publications but had comparatively less interaction with other countries. Both thematic evolution and co-occurrence network analysis showed low numbers of topics such as failure, resection, and safety among the publications but large numbers of highly cited papers on outcomes, prediction, mechanisms, multicenter analysis, and novel procedures such as liver venous deprivation. A total of 196 studies focused the clinical application of ALPPS, and most studies were IDEAL Stages I and II. The specific mechanism of ALPPS liver regeneration remains unclear. CONCLUSIONS This is the first bibliometric analysis offering an overview of the development of ALPPS research publications. Our findings identified prominent studies, countries, institutions, journals, and authors to indicate the future direction of ALPPS research. The role of ALPPS in liver regeneration and the long-term results of ALPPS need further study. Future research directions include comparison of ALPPS with portal vein embolization, liver venous deprivation, and other two-stage hepatectomies as well as patients' quality of life after ALPPS.

Reporting guideline for the early-stage clinical evaluation of decision support systems driven by artificial intelligence: DECIDE-AI. Nat Med 2022; 28:924-933.

Abstract
A growing number of artificial intelligence (AI)-based clinical decision support systems are showing promising performance in preclinical, in silico evaluation, but few have yet demonstrated real benefit to patient care. Early-stage clinical evaluation is important to assess an AI system's actual clinical performance at small scale, ensure its safety, evaluate the human factors surrounding its use and pave the way to further large-scale trials. However, the reporting of these early studies remains inadequate. The present statement provides a multi-stakeholder, consensus-based reporting guideline for the Developmental and Exploratory Clinical Investigations of DEcision support systems driven by Artificial Intelligence (DECIDE-AI). We conducted a two-round, modified Delphi process to collect and analyze expert opinion on the reporting of early clinical evaluation of AI systems. Experts were recruited from 20 pre-defined stakeholder categories. The final composition and wording of the guideline was determined at a virtual consensus meeting. The checklist and the Explanation & Elaboration (E&E) sections were refined based on feedback from a qualitative evaluation process. In total, 123 experts participated in the first round of Delphi, 138 in the second round, 16 in the consensus meeting and 16 in the qualitative evaluation. The DECIDE-AI reporting guideline comprises 17 AI-specific reporting items (made of 28 subitems) and ten generic reporting items, with an E&E paragraph provided for each. Through consultation and consensus with a range of stakeholders, we developed a guideline comprising key items that should be reported in early-stage clinical studies of AI-based decision support systems in healthcare. By providing an actionable checklist of minimal reporting items, the DECIDE-AI guideline will facilitate the appraisal of these studies and replicability of their findings.

Abstract
PURPOSE OF REVIEW The role of focal therapy for the treatment of prostate cancer is expanding in clinical practice. The aim of this review is to introduce readers to controversies in the use of focal therapy and its rationale. RECENT FINDINGS There is a growing body of literature regarding the short-term and medium-term cancer control parameters and quality of life outcomes. These are mostly observational studies without a comparative arm. There is a need for high-quality randomize control trials comparing these treatments to definitive standard of care interventions (e.g. surgery or radiotherapy) in appropriate patient populations. SUMMARY Focal therapy for prostate cancer has become an established therapeutic strategy. Evidence continues to accrue regarding its effectiveness. It is a useful treatment option for the appropriately selected patient, with the appeal of improved quality of life compared with standard therapies.

Abstract
From a pathophysiological point of view, early neurosurgical treatment seems essential to prevent secondary brain injury and has been stated as the "time-is-brain" concept. However, the question immediately rises: "Is there an optimal time window for acute intracranial neurosurgical interventions?" In neurosurgery, treatment modality has been studied far more extensively than timing to surgery ("time-to-surgery"). The majority of acute intracranial neurosurgical interventions are carried out for traumatic brain injury and hemorrhagic or ischemic stroke. Current guidelines for traumatic brain injury, spontaneous intracerebral hemorrhage, aneurysmal subarachnoid hemorrhage, and middle cerebral artery infarction are reviewed and lessons learned from the randomized controlled trials mentioned are discussed. In acute intracranial neurosurgical interventions, "delayed consent" procedures could play an important role for this field of research. Whether there is an optimal time window for acute intracranial neurosurgical interventions seems difficult to be answered with randomized controlled trials referred to in the current guidelines. Observational designs, such as comparative effectiveness research, and special statistical techniques, may provide a better understanding in the optimal "time-to-surgery."

Abstract
Background The utilisation of robot-assisted radical cystectomy with intracorporeal reconstruction (iRARC) has increased in recent years. Little is known about the length of the learning curve (LC) for this procedure. Objective To study the length of the LC for iRARC in terms of 90-d major complications (MC90; Clavien-Dindo grade ≥3), 90-d overall complications (OC90, Clavien-Dindo grades 1–5), operating time (OT), estimated blood loss (EBL), and length of hospital stay (LOS). Design, setting, and participants This was a retrospective analysis of all consecutive iRARC cases from nine European high-volume hospitals with ≥100 cases. All patients had bladder cancer for which iRARC was performed, with an ileal conduit or neobladder as the urinary diversion. Outcome measurements and statistical analysis Outcome parameters used as a proxy for LC length were the number of consecutive cases needed to reach a plateau level in two-piece mixed-effects models for MC90, OC90, OT, EBL, and LOS. Results and limitations A total of 2186 patients undergoing iRARC between 2003 and 2018were included. The plateau levels for MC90 and OC90 were reached after 137 cases (95% confidence interval [CI] 80–193) and 97 cases (95% CI 41–154), respectively. The mean MC90 rate at the plateau was 14% (95% CI 7–21%). The plateau level was reached after 75 cases (95% CI 65–86) for OT, 88 cases (95% CI 70–106) for EBL, and 198 cases (95% CI 130–266) for LOS. A major limitation of the study is the difference in the balance of urinary diversion types between centres. Conclusions This multicentre retrospective analysis for the iRARC LC among nine European centres showed that 137 consecutive cases were needed to reach a stable MC90 rate. Patient summary We carried out a multicentre analysis of the surgical learning curve for robot-assisted removal of the bladder and bladder reconstruction in patients with bladder cancer. We found that 137 consecutive cases were needed to reach a stable rate of serious complications.

Abstract
Background Soractelite™ transperineal focal laser ablation (TPLA) for the treatment of localized prostate cancer (PCa) using the Echolaser® system is a novel minimally invasive technique that has the potential to induce tissue ablation, while reducing treatment-related morbidity, when compared with robot-assisted radical prostatectomy (RARP) and radiotherapy. Objective To determine the short-term safety and feasibility of single or multifiber TPLA, its functional outcomes, and quality of life (QoL). Design, setting, and participants TPLA was performed in 12 patients, consecutively assigned to four treatment regimens, with localized PCa who were scheduled for RARP (“ablate and resect design”). The treatment regimens were as follows: (1) a single fiber at 3 W, (2) two fibers at 5 mm distance at 3 W, (3) two fibers at 10 mm distance at 3 W, and (4) a single fiber at 5 W. TPLA was scheduled 4 wk prior to RARP. Intervention TPLA using the Echolaser® system under local anesthesia at the outpatient clinic. Outcome measurements and statistical analysis Safety and feasibility were determined by the assessment of device-related peri- and postoperative adverse events (AEs), and length of hospital stay. Functional outcomes and QoL were measured using validated questionnaires. Feasibility of RARP was assessed by a questionnaire for the urologist. Results and limitations Patients were dismissed after a median (interquartile range) hospital admission of 3.25 (1.25) h. No device-related AEs occurred. AEs that occurred were mostly related to lower urinary tract symptoms and were mild (grade 1–2). Most AEs resolved within 1 wk. A QoL analysis showed no significant differences for all treatment regimens. Functional outcomes remained unchanged, except for erectile function after 1 wk, which returned to baseline after 4 wk. TPLA treatment did not compromise RARP, based on the questionnaires. Conclusions TPLA for the treatment of PCa at the outpatient clinic appears to be safe and feasible with good short-term QoL and functional outcomes; oncological results are awaited. Patient summary Focal treatment of localized prostate cancer can safely be performed in a daycare setting using a new technique, based on laser ablation, without compromising quality of life.

Abstract
Background Rectovaginal fistulas (RVFs) are abnormal communications between the rectum/anus and the vagina. They are most frequently formed a result of obstetric injury and have deleterious effects on patients’ quality of life. Despite several treatment modalities, RVFs remain difficult problems to manage, and many patients fail multiple attempts at surgical repair. Buccal mucosal grafts (BMGs) may be a solution to this problem. A BMG is an oral mucosal tissue harvested from the inner cheek. There are 2 case reports that describe the successful use of BMGs in the repair of RVFs. Objective Our objective is to validate these findings with a prospective case series while also addressing the key issues of indication, technical details, procedure safety, and short-term outcomes. Methods A prospective single-surgeon case series will be undertaken at a university-affiliated academic tertiary care hospital in Calgary, Alberta (Canada). The estimated recruitment is between 3 and 5 patients. Patients will undergo surgical repair of their RVFs with an autologous BMG. Data on patient characteristics, fistula characteristics, and surgical variables will be collected and analyzed prospectively. The primary outcome is fistula closure. This study has been approved by the Conjoint Health Research Ethics Board at the University of Calgary (REB20-1123). Results Two previous case reports have described the successful use of BMGs in the repair of RVFs. We have received ethics approval to attempt to validate these findings through a prospective case series. Conclusions RVFs cause significant patient morbidity and are difficult problems to manage. Bolstered by the successful use of BMGs in urologic surgery and the previously published case reports demonstrating success in RVFs, we believe that BMGs may be a solution to RVFs.

Abstract
OBJECTIVE Outcome selection and reporting in studies of novel surgical procedures and devices lacks standardisation, hindering safe and effective evaluation. A core outcome set (COS) to measure and report in all studies of surgical innovation is needed. We explored outcomes in a specific sample of innovative surgical device case studies to identify outcome domains specifically relevant to innovation to inform the development of a COS. DESIGN A targeted review of 11 purposive selected case studies of innovative surgical devices. METHODS Electronic database searches in PubMed (July 2018) identified publications reporting the introduction and evaluation of each device. Outcomes were extracted and categorised into domains until no new domains were conceptualised. Outcomes specifically relevant to evaluating innovation were further scrutinised. RESULTS 112 relevant publications were identified, and 5926 outcomes extracted. Heterogeneity in study type, outcome selection and reporting was observed across surgical devices. Categorisation of outcomes was performed for 2689 (45.4%) outcomes into five broad outcome domains. Outcomes considered key to the evaluation of innovation (n=66; 2.5%) were further categorised as surgeon/operator experience (n=40; 1.5%), unanticipated events (n=15, 0.6%) and modifications (n=11; 0.4%). CONCLUSION Outcome domains unique to evaluating innovative surgical devices have been identified. Findings have been combined with multiple other data sources relevant to the evaluation of surgical innovation to inform the development of a COS to measure and report in all studies evaluating novel surgical procedures/devices.

Abstract
PURPOSE To perform a dynamic evaluation of the prostate cancer (PCa) detection rate according to the biopsy strategy over 10 years of practice in a single institution that pioneered MRI-targeted fusion biopsy (MRI-TB). METHODS This stage 4 IDEAL study prospectively included all consecutive patients who underwent transrectal prostate biopsy for clinically suspected PCa between January 2010 and November 2020. Patients with positive MRI (PIRADS score ≥ 3) underwent both MRI-TB and systematic biopsy (SB) while those with negative MRI (PIRADS score < 3) underwent SB only. The main outcome was the evolution of the detection rate of clinically relevant PCa (csPCa; grade ≥ 2). The secondary outcome was the change in PCa detection rate according to the biopsy method. RESULTS A total of 2942 men underwent prostate MRI and a prostate biopsy: 2322 underwent MRI-TB and 620 had SB only. The detection rate of csPCa increased 2.5-fold from 23 to 58%. The detection rate of PCa and csPCa was significantly higher in patients who underwent MRI-TB compared to those who underwent SB only (67% vs. 52% and 40% vs. 32%, respectively (P < 0.001 for both comparisons)). The number of csPCa diagnosed by MRI-TB increased linearly over the study period and represented the majority of PCa diagnoses after 2016. CONCLUSION Implementation of MRI-TB in patients with positive MRI led to improved detection of csPCa.

Use of Image-Guided Surgical Navigation during Resection of Locally Recurrent Rectal Cancer. Life (Basel) 2022; 12:life12050645.

Abstract
Surgery for locally recurrent rectal cancer (LRRC) presents several challenges, which is why the percentage of inadequate resections of these tumors is high. In this exploratory study, we evaluate the use of image-guided surgical navigation during resection of LRRC. Patients who were scheduled to undergo surgical resection of LRRC who were deemed by the multidisciplinary team to be at a high risk of inadequate tumor resection were selected to undergo surgical navigation. The risk of inadequate surgery was further determined by the proximity of the tumor to critical anatomical structures. Workflow characteristics of the surgical navigation procedure were evaluated, while the surgical outcome was determined by the status of the resection margin. In total, 20 patients were analyzed. For all procedures, surgical navigation was completed successfully and demonstrated to be accurate, while no complications related to the surgical navigation were discerned. Radical resection was achieved in 14 cases (70%). In five cases (25%), a tumor-positive resection margin (R1) was anticipated during surgery, as extensive radical resection was determined to be compromised. These patients all received intraoperative brachytherapy. In one case (5%), an unexpected R1 resection was performed. Surgical navigation during resection of LRRC is thus safe and feasible and enables accurate surgical guidance.

Abstract
PURPOSE The Retzius-sparing (RS) approach represents an important surgical innovation in how robotic-assisted laparoscopic prostatectomy (RALP) is performed.The aim of this study was to examine to what extent its development has followed the Idea, Development, Evolution, Assessment and Long-term study (IDEAL) recommendations. MATERIAL AND METHODS We conducted a comprehensive literature search for studies up to the 18th of March 2021. Abstracted data-points included authorship, year of publication, study design, reported endpoints, and length-of follow-up. We mapped each study to the five IDEAL stages of surgical innovation using published criteria. RESULTS Of 415 references, 118 were included in our analysis. Five academic centers authored over 50% of all study reports, with the groups from Seoul (24; 20.3%), Milan (15; 12.7%) and Ninjang (10; 8.5%) being the main contributors. Approximately 40% of studies (50/118) were reported as full-text publications. Most of the reports mapped to retrospective studies (97/118; 82.2%) with approximately one-third (31/97; 32.0%) reporting the use of prospectively collected data. Cumulatively, 17,974 RS-RALP were reported on. Of those, 13,929 were unique cases. Approximately 23% of cases were reported in multiple publications (4,045/17,974). We mapped two, 12, and three studies to the Idea, Assessment and Long-term study stages, respectively, and zero to the Development and Evaluation stages. CONCLUSIONS Few reported studies followed the IDEAL stages for surgical innovation; none addressed the stages of Development and Evaluation. Future systematic, prospectively planned assessments would be helpful to refine the approach and address issues related to the surgical learning curve.

Endoscopic sinus surgery with medical therapy versus medical therapy for chronic rhinosinusitis with nasal polyps: a multicentre, randomised, controlled trial. THE LANCET. RESPIRATORY MEDICINE 2022; 10:337-346. [PMID: 35012708 DOI: 10.1016/s2213-2600(21)00457-4] [Citation(s) in RCA: 32] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/05/2021] [Accepted: 10/05/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Endoscopic sinus surgery (ESS) is a common operation for patients with chronic rhinosinusitis with nasal polyps (CRSwNP) when medical therapy alone is insufficient. No randomised controlled trials on the efficacy of ESS have been published. We aimed to assess the efficacy of ESS plus medical therapy versus medical therapy alone in patients with CRSwNP. METHODS We performed an open-label, multicentre, pragmatic, randomised, controlled trial in three tertiary care centres and 12 secondary care centres in 11 cities in the Netherlands (Almere, Amstelveen, Amsterdam, Blaricum, Den Haag, Deventer, Haarlem, Hoofddorp, Hoorn, Leiderdorp, and Rotterdam). Adults (aged ≥18 years) with CRSwNP and an indication for ESS were randomly assigned (1:1) using block randomisation (block sizes of six), stratified by study centre, to receive either ESS plus medical therapy or medical therapy. ESS was performed according to local practice, although anterior ethmoidectomy was mandatory. Medical therapy was prescribed at the patient's otorhinolaryngologist's discretion, and could be, but was not limited to, nasal corticosteroids, nasal rinsing, systemic corticosteroids, or systemic antibiotics. The primary outcome was disease-specific health-related quality of life (HRQoL) at 12 months of follow up, measured with the validated Sinonasal Outcome Test 22 (SNOT-22; where each item is scored from 0 to 5, where 0 indicated no problems and 5 indicates problems as bad as can be, with a total score of 0-110 points), and the minimal clinically important difference of the SNOT-22 is 9·0 points. Primary and safety analyses were performed on an intention-to-treat (ITT) basis. The ITT population comprised all patients who were randomly assigned to treatment according to their randomisation group and without any protocol violation. This study is registered with the Netherlands Trial Register, NTR4978, and is ongoing. FINDINGS Between Feb 15, 2015, and Aug 27, 2019, 371 patients were screened for eligibility, of whom 238 were eligible, willing to participate, and randomly assigned to ESS plus medical therapy (n=121) or medical therapy (n=117) and 234 were included in the baseline ITT population (n=118 ESS plus medical therapy; n=116 medical therapy). 142 (61%) of 234 patients at baseline were men and 92 (39%) were women, and the mean age was 50·4 years (SD 12·7). 206 participants were analysed at 12 months for the primary outcome (n=103 in the ESS plus medical therapy group; n=103 in the medical therapy group). At 12 months follow-up, the mean SNOT-22 score in the ESS plus medical therapy group was 27·9 (SD 20·2; n=103) and in the medical therapy group was 31·1 (20·4; n=103), with an adjusted mean difference of -4·9 (95% CI -9·4 to -0·4), favouring ESS plus medical therapy. Adverse events were similar between the groups. The most common adverse events were minor epistaxis or gastrointestinal problems. No treatment-related deaths occurred, but one patient died due to congestive heart failure. INTERPRETATION ESS plus medical therapy is more efficacious than medical therapy alone in patients with CRSwNP, although the minimal clinically important difference was not met. Long-term follow-up data are needed to determine whether the effect persists. The current results are a basis for further development of evidence-based guidelines.

Abstract
PURPOSE Anastomotic leakage (AL) is the anathema of colorectal surgery. Its occurrence leads to increased morbidity and mortality and a prolonged hospital stay. Much work has gone into studying various biomarkers in drain fluid to facilitate early detection of AL. This stage 2a development study aims to assess the safety and feasibility of reliably detecting the iodine in Gastrografin (GG; Bayer Australia Ltd.) in drain fluid and stool samples by dual-energy computed tomography (DECT). METHODS This is a prospective, observational, controlled, consecutive cohort study establishing the safety and feasibility of the detection of GG in surgical drain fluid and stool as a biomarker of AL when patients with a low pelvic colorectal anastomosis undergo luminal flushing of the rectal tube with GG. RESULTS Ten consecutive patients were allocated to the saline flush group and the following 10 to the GG flush group. Three patients in the saline flush group developed an AL. One patient in the GG flush group developed an AL. An elevation in the drain fluid GG was detected using DECT on the day of clinical deterioration. None of the patients in the control group were found to have a positive result on DECT. CONCLUSION This study demonstrates the safety of a novel approach to the early detection of AL from extraperitoneal colorectal anastomoses. The technique requires validation in a larger cohort and a multicenter study is planned to investigate the efficacy of GG rectal tube flushes as an early biomarker of AL in low pelvic anastomoses.

Abstract
INTRODUCTION The utility of mucous fistula refeeding (MFR) in neonates with short bowel syndrome is widely debated. Our purpose is to review MFR and outline methods, reported complications, and clinical outcomes (survival, weight gain, dependence on parenteral nutrition [PN], and time to enteral autonomy). MATERIALS AND METHODS We performed a MEDLINE literature search and reference review from January 1980 to May 2020 for terms ("mucous fistula re-feeding" or "enteral re-feeding") and neonates. We included studies that utilized conventional MFR in the neonatal period. Non-English language articles were excluded. RESULTS We identified 11 relevant articles. Internationally, there was no consensus on methods of MFR. A total of 197 neonates underwent MFR. Within a single study, four neonates developed major complications; however, the procedure was well tolerated without major complications in 10 of the 11 studies. A mortality of nine patients during MFR highlights the burden of disease within the study population; however, of these, only one was directly attributable to MFR. Minor complications were seldom quantified. Three studies demonstrated a higher rate of weight gain and shorter PN support versus controls. Neonates who underwent MFR had lower chance of anastomotic leak and quicker progression to full feed after reversal versus controls. The influence of microorganisms in MFR was only investigated in one study. CONCLUSION Current evidence suggests benefits of MFR; however, an international consensus is yet to be reached on the optimal method. A large prospective study investigating the influence of MFR on the enteric system is required.

Clinical implementation and initial experience with a 1.5 Tesla MR-linac for MR-guided radiotherapy for gynecologic cancer: An R-IDEAL stage 1/2a first in humans/feasibility study of new technology implementation. Pract Radiat Oncol 2022; 12:e296-e305. [PMID: 35278717 DOI: 10.1016/j.prro.2022.03.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 02/23/2022] [Accepted: 03/01/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Magnetic resonance imaging-guided linear accelerator systems (MR-linacs) can facilitate the daily adaptation of radiotherapy plans. Here, we report our early clinical experience using an MR-linac for adaptive radiotherapy of gynecologic malignancies. METHODS AND MATERIALS Treatments were planned with an Elekta Monaco v5.4.01 and delivered by a 1.5 Tesla Elekta Unity MR-linac. The system offers a choice of daily adaptation based on either position (ATP) or shape (ATS) of the tumor and surrounding normal structures. The ATS approach has the option of manually editing the contours of tumors and surrounding normal structures before the plan is adapted. Here we documented the duration of each treatment fraction; set-up variability (assessed by isocenter shifts in each plan) between fractions; and, for quality assurance, calculated the percentage of plans meeting the γ-criterion of 3%/3-mm distance to agreement. Deformable accumulated dose calculations were used to compare accumulated versus planned dose for patient treated with exclusively ATP fractions. RESULTS Of the 10 patients treated with 90 fractions on the MR-linac, most received boost doses to recurrence in nodes or isolated tumors. Each treatment fraction lasted a median 32 minutes; fractions were shorter with ATP than with ATS (30 min vs 42 min, P<0.0001). The γ criterion for all fraction plans exceeded >90% (median 99.9%, range 92.4%-100%), i.e., all plans passed quality assurance testing. The average extent of isocenter shift was <0.5 cm in each axis. The accumulated dose to the gross tumor volume was within 5% of the reference plan for all ATP cases. Accumulated doses for lesions in the pelvic periphery were within <1% of the reference plan as opposed to -1.6% to -4.4% for central pelvic tumors. CONCLUSIONS The MR-linac is a reliable and clinically feasible tool for treating patients with gynecologic cancer.

Abstract
Background At times, clinical case complexity and different types of uncertainty present challenges to less experienced clinicians or the naive application of clinical guidelines where this may not be appropriate. Cognitive task analysis (CTA) methods are used to elicit, document and transfer tacit knowledge about how experts make decisions. Methods We conducted a methodological review to describe the use of CTA methods in understanding expert clinical decision-making. We searched MEDLINE, EMBASE and PsycINFO from inception to 2019 for primary research studies which described the use of CTA methods to understand how qualified clinicians made clinical decisions in real-world clinical settings. Results We included 81 articles (80 unique studies) from 13 countries, published from 1993 to 2019, most commonly from surgical and critical care settings. The most common aims were to understand expert decision-making in particular clinical scenarios, using expert decision-making in the development of training programmes, understanding whether decision support tools were warranted and understanding procedural variability and error identification or reduction. Critical decision method (CDM) and CTA interviews were most frequently used, with hierarchical task analysis, task knowledge structures, think-aloud protocols and other methods less commonly used. Studies used interviews, observation, think-aloud exercises, surveys, focus groups and a range of more CTA-specific methodologies such as the systematic human error reduction and prediction approach. Researchers used CTA methods to investigate routine/typical (n = 64), challenging (n = 13) or more uncommon, rare events and anomalies (n = 3). Conclusions In conclusion, the elicitation of expert tacit knowledge using CTA has seen increasing use in clinical specialties working under challenging time pressures, complexity and uncertainty. CTA methods have great potential in the development, refinement, modification or adaptation of complex interventions, clinical protocols and practice guidelines.

Abstract
Objectives Safe implementation and thorough evaluation of new treatments require prospective data monitoring and standardization of treatments. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a promising alternative for the treatment of patients with peritoneal disease with an increasing number of suggested drug regimens. The aim was to reach expert consensus on current PIPAC treatment protocols and to define the most important research topics. Methods The expert panel included the most active PIPAC centers, organizers of PIPAC courses and principal investigators of prospective studies on PIPAC. A comprehensive literature review served as base for a two-day hybrid consensus meeting which was accompanied by a modified three-round Delphi process. Consensus bar was set at 70% for combined (strong and weak) positive or negative votes according to GRADE. Research questions were prioritized from 0 to 10 (highest importance). Results Twenty-two out of 26 invited experts completed the entire consensus process. Consensus was reached for 10/10 final questions. The combination of doxorubicin (2.1 mg/m2) and cisplatin (10.5 mg/m2) was endorsed by 20/22 experts (90.9%). 16/22 (72.7%) supported oxaliplatin at 120 with potential reduction to 90 mg/m2 (frail patients), and 77.2% suggested PIPAC-Ox in combination with 5-FU. Mitomycin-C and Nab-paclitaxel were favoured as alternative regimens. The most important research questions concerned PIPAC conditions (n=3), standard (n=4) and alternative regimens (n=5) and efficacy of PIPAC treatment (n=2); 8/14 were given a priority of ≥8/10. Conclusions The current consensus should help to limit heterogeneity of treatment protocols but underlines the utmost importance of further research.

Abstract
Objectives Precision Robotics’ Sirius Robotic Flexible Endoscopic System is a new, fully integrated, compact three-dimensional laparoscopic camera system with a disposable single-use flexible tip that can change its viewing direction. This IDEAL Stage 1 and 2a study assessed its safety, reliability and potential efficacy particularly for single incision laparoscopic surgery and vaginal natural orifice transluminal endoscopic surgery. Design Prospective single-institution, single-surgeon study. Setting The study was conducted in a multispecialty hospital. Participants Women aged 18–70 years scheduled for gynecological laparoscopic surgery were invited to participate. An information sheet and consent was available for the women and an informed consent was obtained. Thirteen participants completed this study. Interventions The laparoscopic procedures were done in the usual manner. The only difference was the Sirius System was used in place of the conventional laparoscope. All other procedures and instruments remained the same. Main outcome measures Primary outcome was the proportion of women who successfully completed the intended procedure using the Sirius System without conversion to another camera system, camera users and surgeon’s view and experience, and iterations and modifications to the system. Secondary outcomes were the incidence of intraoperative and postoperative complications during the first 6 weeks following surgery, and duration of surgery. Results 85% (11/13) of women had their procedure completed successfully using the Sirius System. Two women required immediate conversion to the conventional laparoscope due to technical issues. There were no intraoperative complications. Users agreed that the improved field of view was beneficial for laparoscopic surgery. Iterative improvements were made in the imaging quality, user interface and manufacturing quality. Conclusions Sirius System has early indications for safety and efficacy for intermediate and major minimally invasive laparoscopic procedures in gynecology. Further studies are needed to confirm it can replace a conventional laparoscope in the surgical workflow. Trial registration number NCT05048407.

Abstract
Background Absolute uterine factor infertility affects 0. 2% women of childbearing age around the world. Uterine transplantation (UTx) is a promising solution for many of them since the first birth from UTx was described by the Swedish team in 2014. The success of Utx in humans has become possible after a systematic and meticulous approach involving years of research on animal models. To date, more than 80 UTx procedures have been performed worldwide and 30 children were born. Material and Method This review summarizes the research preparation conducted in animals before beginning UTx in humans. It focuses on the advantages and limits of each animal model, their place in surgical training, and current contribution in research to improve UTx successes in humans. The different steps in the process of UTx have been analyzed, such as imaging, surgery, ischemia-reperfusion effects, rejection markers, immunosuppressive treatment, and pregnancy. Conclusion Animal models have played an essential role in the implementation of UTx, which is a highly complex procedure. While respecting the 3R requirements (replacement, refinement, and reduction), the surgical training using large animal models, such as notably ewes remain irreplaceable for teams wishing to initiate a UTx program. Furthermore, animal models are still mandatory in current research to improve the success rates of UTx in humans as well as to reduce the morbidity associated with this experimental infertility treatment.

Why do GPs rarely do video consultations? Qualitative study in UK. Br J Gen Pract 2022; 72:e351-e360.

Abstract
Background: Fewer than 1% of UK general practice consultations occur by video. Aim: To explain why video consultations are not more widely used in general practice. Design and setting: Analysis of a sub-sample of data from three mixed-method case studies of remote consultation services in various UK settings 2019-2021. Methods: The dataset included interviews and focus groups with 121 participants from primary care (33 patients, 55 GPs, 11 other clinicians, 9 managers, 4 support staff, 4 national policymakers, 5 technology industry). Data were transcribed, coded thematically and then analysed using the Planning and Evaluating Remote Consultations (PERCS) Framework. Results: With few exceptions, video consultations were either never adopted or soon abandoned in general practice despite a strong policy push, short-term removal of regulatory and financial barriers and advances in functionality, dependability and usability of video technologies (though some products remained “fiddly” and unreliable). The relative advantage of video was perceived as minimal for most of the case load of general practice, since many presenting problems could be sorted adequately and safely by telephone and in-person assessment was considered necessary for the remainder. Some patients found video appointments convenient, appropriate and reassuring but others found therapeutic presence was only achieved in person. Video sometimes added value for out-of-hours and nursing home consultations and statutory functions (e.g. death certification). Conclusion: Efforts to introduce video consultations in general practice should focus on situations where this modality has a clear relative advantage (e.g. strong patient or clinician preference, remote localities, out-of-hours services, nursing homes).

Abstract
INTRODUCTION Surgical innovation has generally occurred in an unstandardised manner. This has led to unnecessary exposure of patients to harm, research waste and inadequate evidence. The IDEAL (Idea, Development, Exploration, Assessment, Long-term follow-up) Collaboration provided a set of recommendations for evaluating surgical innovations based on their stage of innovation. Despite further refinements and guidance, adoption of the IDEAL recommendations has been slow; an important reason may be that determining the stage of innovation is often difficult. To facilitate evaluation of surgical innovations, there is a need for a detailed insight into what stage of innovation means, and how it can be determined. The aim of this study is to understand the concept of stage of innovation as reported in the literature. METHODS AND ANALYSIS A systematic review is being conducted. Ovid MEDLINE and Embase databases were searched from their inception until July 2021 using an iteratively developed strategy based on the concepts of stage of innovation, invasive procedures or devices and guidance. Articles were included if they described an approach to evaluating surgical innovations in stages, described a method for determining stage of innovation, described indicators of stage of innovation, defined stages or described potential sources of stage-related information. Conference abstracts and non-English language articles were excluded. Other articles were detected from citations within included articles and suggestions from experts in surgical innovation. Data will be extracted regarding approaches to evaluating surgical innovations, methods for determining stage of innovation, indicators of stage of innovation, definitions of stages and potential sources of stage-related information. A thematic analysis will be conducted, and findings summarised in a narrative report. ETHICS AND DISSEMINATION Ethical approval will not be required. This systematic review will be published in a peer-reviewed journal and presented at appropriate conferences. PROSPERO REGISTRATION NUMBER CRD42021270812.

Abstract
This study tests fluorescence imaging-derived quantitative parameters for perfusion evaluation of the gastric tube during surgery and correlates these parameters with patient outcomes in terms of anastomotic leakage. Poor fundus perfusion is seen as a major factor for the development of anastomotic leakage and strictures. Fluorescence perfusion imaging may reduce the incidence of complications. Parameters for the quantification of the fluorescence signal are still lacking. Quantitative parameters in terms of maximal intensity, mean slope and influx timepoint were tested for significant differences between four perfusion areas of the gastric tube in 22 patients with a repeated ANOVA test. These parameters were compared with patient outcomes. Maximal intensity, mean slope and influx timepoint were significantly different between the base of the gastric tube and the fundus (p < 0.0001). Patients who developed anastomotic leakage showed a mean slope of almost 0 in Location 4. The distance of the demarcation of ICG to the fundus was significantly higher in the three patients who developed anastomotic leakage (p < 0.0001). This study presents quantitative intra-operative perfusion imaging with fluorescence. Quantification of the fluorescence signal allows for early risk stratification of necrosis.

Abstract
PURPOSE OF REVIEW Exoscopes are external digital devices that provide enhanced and magnified visualization of the surgical field. They usually have dedicated digital controls and a more compact mechanical structure than operative microscopes and current robotic surgical systems. This technology has significant potential in otolaryngology - head and neck surgery, especially concerning the field of transoral approaches. We herein analysed the overall technical characteristics of currently available exoscopic systems and contextualized their advantages and drawbacks in the setting of transoral surgery. RECENT FINDINGS The actual advantages of exoscopy are still indeterminate, as it has only been applied to limited surgical series. However, its specific properties are herein compared with conventional transoral microsurgery and transoral robotic surgery, discussing the available literature on such a topic, filtered on the basis of the authors' experience and its possible future evolutions. Finally, a summary of current experiences in the field of three-dimensional (3D) transoral exoscopic surgery is presented, highlighting differences compared with standard approaches. SUMMARY 3D-exoscopic transoral surgery will possibly play an essential role in future management of early laryngeal and oropharyngeal lesions, significantly shifting the paradigms of this type of procedures.
