Long-term outcomes after hypothermic oxygenated machine perfusion and transplantation of 1,202 donor livers in a real-world setting (HOPE-REAL study). J Hepatol 2024:S0168-8278(24)02341-9. [PMID: 38969242 DOI: 10.1016/j.jhep.2024.06.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 05/26/2024] [Accepted: 06/24/2024] [Indexed: 07/07/2024]
Abstract
BACKGROUND & AIM We aimed to assess long-term outcome after transplantation of HOPE-treated donor livers based on real-world data (i.e., IDEAL-D stage 4). METHODS In this international, multicentre, observational cohort study, we collected data from adult recipients of a HOPE-treated liver transplanted between January 2012 and December 2021. Analyses were stratified for brain-dead (DBD) and circulatory-dead (DCD) donor livers, sub-divided by their respective risk categories. The primary outcome was death-censored graft survival. Secondary outcomes included the incidence of primary non-function (PNF) and ischemic cholangiopathy (IC). RESULTS We report on 1202 liver transplantations (64% DBD) performed at 22 European centres. For DBD, a total number of 99 benchmark (8%), 176 standard (15%), and 493 extended-criteria (41%) cases were included. For DCD, 117 transplants were classified as low-risk (10%), 186 as high-risk (16%), and 131 as futile (11%), with significant risk profile variations among centres. Actuarial 1-, 3-, and 5-year death-censored graft survival for DBD and DCD was 95%, 92%, and 91%, vs. 92%, 87%, and 81%, respectively (logrank p=0.003). Within DBD and DCD-strata, death-censored graft survival was similar among risk groups (logrank p=0.26, p=0.99). Graft loss due to PNF or IC was 2.3% and 0.4% (DBD), and 5% and 4.1% (DCD). CONCLUSIONS This study shows excellent 5-year survival after transplantation of HOPE-treated DBD and DCD livers with low rates of graft loss due to PNF or IC, irrespective of their individual risk profile. HOPE-treatment has now reached IDEAL-D stage 4, which further supports the implementation of HOPE in routine clinical practice. IMPACT AND IMPLICATIONS This study demonstrates the excellent long-term performance of HOPE-treatment of DCD and DBD liver grafts irrespective of their individual risk profile in a real-world setting, outside the evaluation of randomized controlled trials. While previous studies have established safety, feasibility, and efficacy against the current standard, according to the IDEAL-D evaluation framework, HOPE-treatment has now reached the final IDEAL-D Stage 4, which further supports the implementation of HOPE in routine clinical practice. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT05520320.

Ann Surg 2024; 279:1000-1007. [PMID: 38375674 PMCID: PMC11086674 DOI: 10.1097/sla.0000000000006247] [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: 02/21/2024]
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
OBJECTIVE To determine if ultrasound-guided (USG) radiofrequency ablation (RFA) of Parotid Warthin's tumor under local anesthesia is a safe and effective procedure. STUDY DESIGN Safety and feasibility study. SETTING Tertiary academic medical center. METHODS This is an IDEAL phase 2a trial in a tertiary referral center. Twenty patients with Parotid Warthin's tumor were recruited. RFA was done between September and December 2021 for all 20 patients using a CoATherm AK-F200 machine with a disposable, 18G × 7 mm radiofrequency electrode. Results and follow-up statistics were compared with a historic sample of patients with parotid Warthin's tumor who underwent parotidectomy between 2019 and 2021 in the same center. RESULTS Nineteen patients were included in the analysis as 1 patient dropped out after 4 weeks of follow-up. The mean age for the RFA group was 67 years old with most of them being male smokers. At a median of 45 weeks (44-47 weeks) postprocedure there was a 7.48 mL (68.4%) volume reduction compared to baseline. Three patients had transient facial nerve (FN) paresis, 1 recovered within hours, and the other 2 by 12 weeks follow-up. Three patients had great auricular nerve numbness; 1 patient had infected hematoma treated in an out-patient manner. Compared to a historic cohort of parotidectomy patients for Warthin's tumor, there was no significant difference in FN paresis and other minor complications between the 2 treatment modalities. CONCLUSION The current analysis suggests that USG RFA of Warthin's Tumor is a safe alternative to parotidectomy with shorter operative time and length of stay.

Abstract
AbstractThe field of surgery has relied on innovation and creativity to improve patient care and propel the field forward. Historically, regulatory oversight of innovative approaches to surgery has been largely inconsistent, rendering surgeons relatively unrestricted creative latitude in the operating room; whether this has proven to be more beneficial or harmful is subject to debate. While innovation plays a crucial role in the advancement of surgical techniques, the potential drawbacks of unregulated innovation must be seriously considered, especially when treating vulnerable populations such as infants and children. This article provides an overview of the ethical aspects surrounding innovation in pediatric surgery, including discussion of relevant considerations, controversies, and pitfalls. The following includes a review of the current and past literature surrounding the topic. The purpose of this review is to heighten awareness of the ethical challenges that surgeons face when considering novel operative techniques on pediatric patients.

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.

Abstract
The first Lancet Oncology Commission on Global Cancer Surgery was published in 2015 and serves as a landmark paper in the field of cancer surgery. The Commission highlighted the burden of cancer and the importance of cancer surgery, while documenting the many inadequacies in the ability to deliver safe, timely, and affordable cancer surgical care. This Commission builds on the first Commission by focusing on solutions and actions to improve access to cancer surgery globally, developed by drawing upon the expertise from cancer surgery leaders across the world. We present solution frameworks in nine domains that can improve access to cancer surgery. These nine domains were refined to identify solutions specific to the six WHO regions. On the basis of these solutions, we developed eight actions to propel essential improvements in the global capacity for cancer surgery. Our initiatives are broad in scope, pragmatic, affordable, and contextually applicable, and aimed at cancer surgeons as well as leaders, administrators, elected officials, and health policy advocates. We envision that the solutions and actions contained within the Commission will address inequities and promote safe, timely, and affordable cancer surgery for every patient, regardless of their socioeconomic status or geographic location.

Abstract
The vital physiological role of the pituitary gland, alongside its proximity to critical neurovascular structures, means that pituitary adenomas can cause significant morbidity or mortality. While enormous advancements have been made in the surgical care of pituitary adenomas, numerous challenges remain, such as treatment failure and recurrence. To meet these clinical challenges, there has been an enormous expansion of novel medical technologies (eg, endoscopy, advanced imaging, artificial intelligence). These innovations have the potential to benefit each step of the patient's journey, and ultimately, drive improved outcomes. Earlier and more accurate diagnosis addresses this in part. Analysis of novel patient data sets, such as automated facial analysis or natural language processing of medical records holds potential in achieving an earlier diagnosis. After diagnosis, treatment decision-making and planning will benefit from radiomics and multimodal machine learning models. Surgical safety and effectiveness will be transformed by smart simulation methods for trainees. Next-generation imaging techniques and augmented reality will enhance surgical planning and intraoperative navigation. Similarly, surgical abilities will be augmented by the future operative armamentarium, including advanced optical devices, smart instruments, and surgical robotics. Intraoperative support to surgical team members will benefit from a data science approach, utilizing machine learning analysis of operative videos to improve patient safety and orientate team members to a common workflow. Postoperatively, neural networks leveraging multimodal datasets will allow early detection of individuals at risk of complications and assist in the prediction of treatment failure, thus supporting patient-specific discharge and monitoring protocols. While these advancements in pituitary surgery hold promise to enhance the quality of care, clinicians must be the gatekeepers of the translation of such technologies, ensuring systematic assessment of risk and benefit prior to clinical implementation. In doing so, the synergy between these innovations can be leveraged to drive improved outcomes for patients of the future.

Abstract
Surgery is central to the cure of most solid cancers and an integral part of modern multimodal cancer management for early and advanced stage cancers. Decisions made by surgeons and multidisciplinary team members are based on best available knowledge for the defined clinical situation at hand. While surgery is both an art and a science, good decision-making requires data that are robust, valid, representative and, applicable to most if not all patients with a specific cancer. Such data largely comes from clinical observations and registries, and more preferably from trials conducted with the specific purpose of arriving at new answers. As part of the ESSO core curriculum development an increased focus has been put on the need to enhance research literacy among surgical candidates. As an expansion of the curriculum catalogue list and to enhance the educational value, we here present a set of principles and emerging concepts which applies to surgical oncologist for reading, understanding, planning and contributing to future surgeon-led cancer trials.

Abstract
Remote digital postoperative wound monitoring provides an opportunity to strengthen postoperative community care and minimise the burden of surgical-site infection (SSI). This study aimed to pilot a remote digital postoperative wound monitoring service and evaluate the readiness for implementation in routine clinical practice. This was a single-arm pilot implementational study of remote digital postoperative wound monitoring across two tertiary care hospitals in the UK (IDEAL stage 2b, clinicaltrials.gov: NCT05069103). Adults undergoing abdominal surgery were recruited and received a smartphone-delivered wound assessment tool for 30-days postoperatively. Patients received 30-day postoperative follow-up, including the Telehealth Usability Questionnaire (TUQ). A thematic mixed-methods approach was used, according to the WHO framework for monitoring and evaluating digital health interventions. 200 patients were enroled, of whom 115 (57.5%) underwent emergency surgical procedures. Overall, the 30-day SSI rate was 16.5% (n = 33/200), with 72.7% (n = 24) diagnosed post-discharge. Usage of the intervention was 83.0% (n = 166/200), with subsequently 74.1% (n = 123/166) TUQ completion. There were no issues reported with feasibility of the technology, with the reliability (3.87, 95% CI: 3.73-4.00) and quality of the interface rated highly (4.18, 95%: 4.06-4.30). Patient acceptance was similarly high with regards to ease of use (4.51, 95% CI: 4.41-4.62), satisfaction (4.27, 95% CI: 4.13-4.41), and usefulness (4.07, 95% CI: 3.92-4.23). Despite the desire for more frequent and personalised interactions, the majority viewed the intervention as providing meaningful benefit over routine postoperative care. Remote digital postoperative wound monitoring successfully demonstrated readiness for implementation with regards to the technology, usability, and healthcare process improvement.

Abstract
An increasing number of digital health interventions (DHIs) for remote postoperative monitoring have been developed and evaluated. This systematic review identifies DHIs for postoperative monitoring and evaluates their readiness for implementation into routine health care. Studies were defined according to idea, development, exploration, assessment, and long-term follow-up (IDEAL) stages of innovation. A novel clinical innovation network analysis used coauthorship and citations to examine collaboration and progression within the field. 126 DHIs were identified, with 101 (80%) being early stage innovations (IDEAL stage 1 and 2a). None of the DHIs identified had large-scale routine implementation. There is little evidence of collaboration, and there are clear omissions in the evaluation of feasibility, accessibility, and the health-care impact. Use of DHIs for postoperative monitoring remains at an early stage of innovation, with promising but generally low-quality supporting evidence. Comprehensive evaluation within high-quality, large-scale trials and real-world data are required to definitively establish readiness for routine implementation.

Abstract
In patients presenting with colorectal cancer and synchronous liver metastases, the disease burden related to the liver metastasis is the driving cause of limited longevity and, eventually, risk of death. Surgical resection is the potentially curative treatment for colorectal cancer liver metastases. In the synchronous setting where both the liver metastases and the primary tumor are resectable with a relative low risk, the oncological surgeon and the patient may consider three potential treatment strategies. Firstly, a "staged" or a "simultaneous" surgical approach. Secondly, for a staged strategy, a 'conventional approach' will suggest removal of the primary tumor first (either colon or rectal cancer) and plan for liver surgery after recovery from the first operation. A "Liver first" strategy is prioritizing the liver resection before resection of the primary tumor. Planning a surgical trial investigating a two-organ oncological resection with highly variable extent and complexity of resection as well as the potential impact of perioperative chemo(radio)therapy makes it difficult to find the optimal primary endpoint. Here, we suggest running investigational trials with carefully chosen composite endpoints as well as embedded risk-stratification strategies to identify subgroups of patients who may benefit from simultaneous surgery.

Abstract
OBJECTIVE To address instances when there is insufficient remnant tissue to perform revision following canal-deepening gender affirming vaginoplasty revisions as indicated by insufficient depth. Options for lining of the vaginal canal include skin grafts, peritoneal flaps, or intestinal segment. Our center uses robotically harvested peritoneal flaps in vaginal canal revisions. When the peritoneal flap is insufficient for full canal coverage, we use AlloDerm, an acellular dermal matrix, for additional coverage. METHODS Retrospective analysis of 9 patients who underwent revision RPV with AlloDerm was performed. Tubularized AlloDerm grafts were used to connect remnant vaginal lining to the peritoneal flaps. Revision indications, surgical and patient outcomes, and patient-reported post-op dilation were recorded. RESULTS Nine patients underwent revision RPV using AlloDerm for canal deepening. Median follow-up was 368 days (Range 186-550). Following revision, median depth and width at last follow-up were 12.1 cm and 3.5 cm, and median increase in depth and width were 9.7 cm and 0.9 cm, respectively. There were no intraoperative complications. Two patients had focal areas of excess AlloDerm that were treated with in-office excision without compromise of the caliber or depth of the otherwise healed, epithelialized canal. CONCLUSION AlloDerm is an off-the-shelf option that does not require a secondary donor site. The use of AlloDerm for a pilot cohort of patients lacking sufficient autologous tissue for revision RPV alone was demonstrated to be safe and effective at a median 1-year follow-up.

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
INTRODUCTION Pancreatic resections are an important field of surgery worldwide to treat a variety of benign and malignant diseases. Postoperative pancreatic fistula (POPF) remains a frequent and critical complication after partial pancreatectomy and affects up to 50% of patients. POPF increases mortality, prolongs the postoperative hospital stay and is associated with a significant economic burden. Despite various scientific approaches and clinical strategies, it has not yet been possible to develop an effective preventive tool. The SmartPAN indicator is the first surgery-ready medical device for direct visualisation of pancreatic leakage already during the operation. Applied to the surface of pancreatic tissue, it detects sites of biochemical leak via colour reaction, thereby guiding effective closure and potentially mitigating POPF development. METHODS AND ANALYSIS The ViP trial is a prospective single-arm, single-centre first in human study to collect data on usability and confirm safety of SmartPAN. A total of 35 patients with planned partial pancreatectomy will be included in the trial with a follow-up of 30 days after the index surgery. Usability endpoints such as adherence to protocol and evaluation by the operating surgeon as well as safety parameters including major intraoperative and postoperative complications, especially POPF development, will be analysed. ETHICS AND DISSEMINATION Following the IDEAL-D (Idea, Development, Exploration, Assessment, and Long term study of Device development and surgical innovation) framework of medical device development preclinical in vitro, porcine in vivo, and human ex vivo studies have proven feasibility, efficacy and safety of SmartPAN. After market approval, the ViP trial is the IDEAL Stage I trial to investigate SmartPAN in a clinical setting. The study has been approved by the local ethics committee as the device is used exclusively within its intended purpose. Results will be published in a peer-reviewed journal. The study will provide a basis for a future randomised controlled interventional trial to confirm clinical efficacy of SmartPAN.

Abstract
BACKGROUND Investigating neurosurgical interventions for traumatic brain injury (TBI) involves complex methodological and practical challenges. In the present report, we have provided an overview of the current state of neurosurgical TBI research and discussed the key challenges and possible solutions. METHODS The content of our report was based on an extensive literature review and personal knowledge and expert opinions of senior neurosurgeon researchers and epidemiologists. RESULTS Current best practice research strategies include randomized controlled trials (RCTs) and comparative effectiveness research. The performance of RCTs has been complicated by the heterogeneity of TBI patient populations with the associated sample size requirements, the traditional eminence-based neurosurgical culture, inadequate research budgets, and the often acutely life-threatening setting of severe TBI. Statistical corrections can mitigate the effects of heterogeneity, and increasing awareness of clinical equipoise and informed consent alternatives can improve trial efficiency. The substantial confounding by indication, which limits the interpretability of observational research, can be circumvented by using an instrumental variable analysis. Traditional TBI outcome measures remain relevant but do not adequately capture the subtleties of well-being, suggesting a need for multidimensional approaches to outcome assessments. CONCLUSIONS In settings in which traditional RCTs are difficult to conduct and substantial confounding by indication can be present, observational studies using an instrumental variable analysis and "pragmatic" RCTs are promising alternatives. Embedding TBI research into standard clinical practice should be more frequently considered but will require fundamental modifications to the current health care system. Finally, multimodality outcome assessment will be key to improving future surgical and nonsurgical TBI research.

Abstract
A 55-year-old woman with previous skin-sparing mastectomy and prosthetic reconstruction for multifocal ductal carcinoma developed homolateral axillary recurrence. Following nodal dissection, partial periprosthetic capsulectomy and the overlying breast skin excision, the pathology report revealed a positive cutaneous margin. Since further breast skin excision or radiotherapy would have compromised the prosthetic implant, and the patient was adamant about avoiding any endangering intervention, the multidisciplinary recommendation included skin-directed electrochemotherapy (ECT) in the frame of a multimodal treatment strategy. The procedure lasted 20 minutes under mild general sedation and included a bolus of intravenous bleomycin followed by local application of electric pulses using a needle electrode. The postprocedural course was uneventful, except for mild dermatologic toxicity. At 5 years, the patient is disease-free with the implant in situ. This report illustrates the proof-of-concept of adjuvant skin-sparing ECT to sterilize resection margins, preserve a breast implant and highlight procedural details to avert toxicity.

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.

Currie AC, Penney N, Kamocka A, Singh P, Abbassi-Ghadi N, Preston SR. Systematic review on reporting of components and outcomes in randomized clinical trials of paraoesophageal hernia mesh repair. Br J Surg 2021; 108:256-264. [PMID: 33793727 DOI: 10.1093/bjs/znaa107] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 10/20/2020] [Accepted: 11/03/2020] [Indexed: 11/15/2022]
Abstract
BACKGROUND Surgical interventions, such as paraoesophageal hernia (POH) repair, are complex with multiple components that require consideration in the reporting of clinical trials. Many aspects of POH repair, including mesh hiatal reinforcement and fundoplication type, are contentious. This review summarizes the reporting of components and outcomes in RCTs of POH repair. METHODS Systematic searches identified RCTs of POH repair published from 1995 to 2020. The patient selection criteria for RCT involvement were noted. The components of the surgical interventions in these RCTs were recorded using the CONSORT guidelines for non-pharmacological treatments, Template for Intervention Description and Replication (TIDieR) and Blencowe frameworks. The outcomes were summarized and definitions sought for critical variables, including recurrence. RESULTS Of 1918 abstracts and 21 screened full-text articles, 12 full papers reporting on six RCTs were included in the review. The patient selection criteria and definitions of POH between trials varied considerably. Although some description of trial interventions was provided in all RCTs, this varied in depth and detail. Four RCTs described efforts to standardize the trial intervention. Outcomes were reported inconsistently, were rarely defined fully, and overall trial conclusions varied during follow-up. CONCLUSION This lack of detail on the surgical intervention in POH repair RCTs prevents full understanding of what exact procedure was evaluated and how it should be delivered in clinical practice to gain the desired treatment effects. Improved focus on the definitions, descriptions and reporting of surgical interventions in POH repair is required for better future RCTs.

Surgery 2021; 170:1054-1060. [PMID: 34020793 DOI: 10.1016/j.surg.2021.04.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 03/15/2021] [Accepted: 04/05/2021] [Indexed: 12/22/2022]
Abstract
BACKGROUND Designing studies to assess critically novel procedures can be challenging; thus, the process to achieve robust evidence is frequently problematic. The aim of this systematic review was to evaluate if literature on transanal total mesorectal excision is evolving according to the Idea, Development, Exploration, Assessment, and Long-term results framework. METHODS Literature on transanal total mesorectal excision was searched according to the preferred reporting items for systematic reviews and meta-analyses statement, and these variables were recorded: bibliometric data, design, corresponding author's nationality, number of patients enrolled, and Idea, Development, Exploration, Assessment, and Long-term results stages (stage 0, stage 1, stage 2, stage 3, and stage 4). RESULTS Out of 447 articles retrieved, 247 were selected (76.5% single center and 23.5% multicenter collaborations), including 35 reviews, 15 meta-analyses, 24 other publications, and 173 articles classified according to Idea, Development, Exploration, Assessment, and Long-term results stages (19 stage 0, 27 stage 1, 111 stage 2, 7 stage 3, and 9 stage 4). Overall, impact factor produced was 634.10. Reviewing corresponding authors' nationalities, 32 countries were identified, and the most reported were the United States, China, and the United Kingdom; nearly all were from the Northern Hemisphere. Publication of stage 3 and 4 articles started in 2014, whereas stage 0 and 1 articles were stably published over time. The number of patients increased in correspondence with the Idea, Development, Exploration, Assessment, and Long-term results stages (case series with >51 patients, respectively, 100.0% stage 3, 77.8% stage 4, and 33.3% stage 2, P = .005). CONCLUSION The number of stage 3 and 4 articles is still low; however, the technical innovation of transanal total mesorectal excision is a non-stopping process with preclinical studies stably published over time.

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
The purpose of the study was to evaluate the trend in documentation of surgeon level of expertise among the Journal of Hand Surgery (American Volume) and the Journal of Hand Surgery (European Volume) publications. A review of Journal of Hand Surgery (American Volume) and Journal of Hand Surgery (European Volume) databases for level of expertise between January 2015 and October 2019 was performed. Of 1042 articles identified, all 115 (20%) reporting level of expertise were published in Journal of Hand Surgery (European Volume). Since 2015, there has been an increase in reported level of expertise in Journal of Hand Surgery (European Volume) (2015: 8 (7%); 2016: 15 (13%); 2017: 22 (19%); 2018: 28 (24%); 2019: 42 (37%)). In the same period, no publications have reported level of expertise in Journal of Hand Surgery (American Volume). Documenting level of expertise may provide readers with additional information for incorporation of novel techniques into their practices. It may identify procedures that require a baseline level of expertise for effective performance. Further evaluation of level of expertise criteria may improve the reliability of the numeric scale, while widespread adoption of this scale will allow future outcome analysis by level of expertise.

Abstract
BACKGROUND Medical devices introduced to market through the 510K process often have limited research of low quality and substantial conflict of interest (COI). By the time high-quality safety and effectiveness research is performed, thousands of patients may have already been treated by the device. Our aim was to systematically review the trends of outcomes, research quality, and financial relationships of published studies related to de-adopted meshes for ventral hernia repair. MATERIALS AND METHODS Literature was systematically reviewed using PubMed to obtain all published studies related to three de-adopted meshes: C-QUR, Physiomesh, and meshes with polytetrafluoroethylene. Primary outcome was change in cumulative percentage of subjects with positive published outcomes. Secondary outcome was percentage of published manuscript with COI. RESULTS A total of 723 articles were screened, of which, 129 were analyzed and included a total of 8081 subjects. Percentage of subjects with positive outcomes decreased over time for all groups: (1) C-QUR from 100% in 2009 to 22% in 2018, (2) Physiomesh from 100% in 2011 to 20% in 2018, and (3) polytetrafluoroethylene from 100% in 1979 to 49% in 2018. Authors of only 20% of articles self-reported no COI, most representing later publications and were more likely to show neutral or negative results. CONCLUSIONS Among three de-adopted meshes, early publications demonstrated overly optimistic results followed by disappointing outcomes. Skepticism over newly introduced, poorly proven therapies is essential to prevent adoption of misleading practices and products. Devices currently approved under the 510K processes should undergo blinded, randomized controlled trials before introduction to the market.
