[PMID: 38969242 DOI: 10.1016/j.jhep.2024.06.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [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 & AIMS Despite strong evidence for improved preservation of donor livers by machine perfusion, longer post-transplant follow-up data are urgently needed in an unselected patient population. We aimed to assess long-term outcomes after transplantation of hypothermic oxygenated machine perfusion (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 HOPE-treated livers transplanted between January 2012 and December 2021. Analyses were stratified by donation after brain death (DBD) and donation after circulatory death (DCD), 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 ischaemic cholangiopathy (IC). RESULTS We report on 1,202 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 rates for DBD and DCD livers were 95%, 92%, and 91%, vs. 92%, 87%, and 81%, respectively (log-rank p = 0.003). Within DBD and DCD strata, death-censored graft survival was similar among risk groups (log-rank 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 its implementation in routine clinical practice. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT05520320. IMPACT AND IMPLICATIONS This study demonstrates the excellent long-term performance of hypothermic oxygenated machine perfusion (HOPE) treatment of donation after circulatory and donation after brain death liver grafts irrespective of their individual risk profile in a real-world setting, outside the evaluation of randomised-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 its implementation in routine clinical practice.

Reporting of Complications in Rhinoplasty Randomized Controlled Trials: An Analysis Using the CONSORT Extension for Harms Checklist. Otolaryngol Head Neck Surg 2024; 171:81-89. [PMID: 38613190 DOI: 10.1002/ohn.765] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 01/02/2024] [Accepted: 02/05/2024] [Indexed: 04/14/2024]
Abstract
OBJECTIVE This study aimed to assess the completeness of adverse event (AE) reporting in randomized control trials (RCTs) focused on rhinoplasty, using the Consolidated Standards for Reporting (CONSORT) Extension for Harms checklist. STUDY DESIGN A cross-sectional design was employed to review RCTs related to rhinoplasty published between January 1, 2005, and January 28, 2022. SETTING The study analyzed clinical trials on rhinoplasty retrieved from PubMed. METHODS We performed a comprehension search on PubMed, blind and duplicate screening, and data extraction. Adherence to the 18 recommendations of the CONSORT Extension for Harms was evaluated, with 1 point assigned for each adhered item. Percent adherence was calculated based on the 18 points, taking into account the multiple subcategories within some recommendations. Descriptive statistics were used to summarize adherence-including frequencies, percentages, and 95% confidence intervals. RESULTS Our search returned 240 articles, of which 56 met inclusion criteria. No RCTs adhered to all 18 CONSORT Extension for Harms items. Twenty-six (26/56, 46.4%) adhered to ≥50% of the items, and 30 (30/56, 53.6%) adhered to ≥33.3% of the items. Seven (7/56, 12.5%) RCTs adhered to no items. Across all RCTs, the average number of CONSORT-Harms items adhered to was 7.2 (7.2/18, 40.0%). The most adhered to item was item 10. Discussion balanced with regard to efficacy and AEs (80.4%, [70.0-90.8]). CONCLUSION This study highlights the inadequacy of AE reporting in rhinoplasty RCTs according to CONSORT-Harms guidelines. Urgent efforts are required to bridge this reporting gap and enhance transparency in surgical research, ultimately safeguarding patient well-being.

Abstract
BACKGROUND Surgical trials are recognised as inherently challenging. Pilot and feasibility studies (PAFS) are increasingly acknowledged as a key method to optimise the design and conduct of randomised trials but remain limited in surgery. We used a mixed methods approach to develop recommendations for how surgical PAFS could be optimised. METHODS The findings from a quantitative analysis of funded surgical PAFS over a 10-year period and in-depth qualitative interviews with surgeons, methodologists and funders were triangulated and synthesised with available methodological guidance on PAFS. RESULTS The synthesis informed the development of an explanatory model describing root causes and compounding challenges that contribute to how and why surgical PAFS is not currently optimised. The four root causes identified include issues relating to (i) understanding the full scope of PAFS; (ii) design and conduct of PAFS; (iii) reporting of PAFS; and (iv) lack of appreciation of the value of PAFS by all stakeholder groups. Compounding challenges relate to both cultural issues and access to and interpretation of available methodological PAFS guidance. The study findings and explanatory model were used to inform the development of a practical guidance tool for surgeons and study teams to improve research practice. CONCLUSIONS Optimisation of PAFS in surgery requires a cultural shift in research practice amongst funders, academic institutions, regulatory bodies and journal editors, as well as amongst surgeons. Our 'Top Tips' guidance tool offers an accessible framework for surgeons designing PAFS. Adoption and utilisation of these recommendations will optimise surgical PAFS, facilitating successful and efficient future surgical trials.

Abstract
Procedure-related registries in general surgical practice offer a platform for prospective trials, the pooling of data, and detailed outcome analysis. Recommendations by the Idea, Development, Exploration, Assessment, and Long-term follow-up (IDEAL) collaboration and Outcome4Medicine have further improved the uniform reporting of complications and adverse events.In the pediatric surgical network, disease-specific registries for rare and inherited congenital anomalies are gaining importance, fostering international collaborations on studies of low-incidence diseases. However, to date, reporting of complications in the pediatric surgical registries has been inconsistent. Therefore, the European Reference Network for Rare Inherited and Congenital Anomalies (ERNICA) recently endorsed the validation of the first severity grading system for children. The planned reform of the European Paediatric Surgical Audit (EPSA) registry, which includes the implementation of the Clavien-Madadi classification, represents a further effort to establish uniform outcome reporting.This article provides an overview of experiences with surgical registries and complication reporting, along with the potential application of this knowledge to future pediatric surgical practice.

Abstract
Importance Guidewires have been the standard for breast lesion localization but pose operative and logistic challenges. Paramagnetic seeds have shown promising results, but to the authors' knowledge, no randomized comparison has been performed. Objective To determine whether the combination of a paramagnetic seed and superparamagnetic iron oxide (SPIO) is equivalent to guidewire and SPIO for breast cancer localization and sentinel lymph node detection (SLND). Design, Setting, and Participants This was a phase 3, pragmatic, equivalence, 2-arm, open-label, randomized clinical trial conducted at 3 university and/or community hospitals in Sweden from May 2018 to May 2022. Included in the study were patients with early breast cancer planned for breast conservation and SLND. Study data were analyzed July to November 2022. Interventions Participants were randomly assigned 1:1 to a paramagnetic seed or a guidewire. All patients underwent SLND with SPIO. Main Outcomes and Measures Re-excision rate and resection ratio (defined as actual resection volume / optimal resection volume). Results A total of 426 women (median [IQR] age, 65 [56-71] years; median [IQR] tumor size, 11 [8-15] mm) were included in the study. The re-excision rate was 2.90% (95% CI, 1.60%-4.80%), and the median (IQR) resection ratio was 1.96 (1.15-3.44). No differences were found between the guidewire and the seed in re-excisions (6 of 211 [2.84%] vs 6 of 209 [2.87%]; difference, -0.03%; 95% CI, -3.20% to 3.20%; P = .99) or resection ratio (median, 1.93; IQR, 1.18-3.43 vs median, 2.01; IQR, 1.11-3.47; P = .70). Overall SLN detection was 98.6% (95% CI, 97.1%-99.4%) with no differences between arms (203 of 207 [98.1%] vs 204 of 206 [99.0%]; difference, -0.9%; 95% CI, -3.6% to 1.8%; P = .72). More failed localizations occurred with the guidewire (21 of 208 [10.1%] vs 4 of 215 [1.9%]; difference, 8.2%; 95% CI, 3.3%-13.2%; P < .001). Median (IQR) time to specimen excision was shorter for the seed (15 [10-22] minutes vs 18 [12-30] minutes; P = .01), as was the total operative time (69 [56-86] minutes vs 75.5 [59-101] minutes; P = .03). The experience of surgeons, radiologists, and surgical coordinators was better with the seed. Conclusions and Relevance The combination of SPIO and a paramagnetic seed performed comparably with SPIO and guidewire for breast cancer conserving surgery and resulted in more successful localizations, shorter operative times, and better experience.

Abstract
The current application of robotic surgery is evolving at a high pace in the current years. The technical advantages enable several abdominal surgical procedures to be performed minimally invasive instead of open surgery. Furthermore, procedures previously performed successfully using standard laparoscopy are now performed with a robotic approach, with conflicting results. The present narrative review reports the current literature on the robotic surgical procedures typically performed in a typical Scandinavian surgical department: colorectal, hernia, hepato-biliary, and esophagogastric surgery.

Abstract
Patients with curable non-surgical lung cancer are often current smokers, have co-existing medical comorbidities and are treated with curative radiotherapy. To maximise the benefits of modern radiotherapy, there is an urgent need to optimise the patient's health to improve survival and quality of life. METHODS AND ANALYSIS The Yorkshire Cancer Research-funded Prehabilitation Radiotherapy Exercise, smoking Habit cessation and Balanced diet Study (PREHABS) (L426) is a single-centre prospective feasibility study to assess embedding behavioural changes into the radical radiotherapy pathway of patients with lung cancer. Feasibility will be assessed by measuring acceptability, demand and implementation. The duration of the study is 24 months. PREHABS has two workstreams: the intervention study and the theory of change (ToC) study.Intervention study: PREHABS will commence at the R-IDEAL phase 2 trial (exploratory) based on existing evidence and includes support for smoking cessation, increasing activity and dietary well-being. Patients undergoing radical radiotherapy for lung cancer will be recruited from the oncology department at Leeds Teaching Hospitals NHS Trust (LTHT). ToC study: to maximise the acceptability and adherence to the PREHABS, we will use a ToC approach to qualitatively explore the key barriers and enablers of implementing a tailored programme of 'prehabilitation'. The PREHABS ToC study participants will be recruited from patients with lung cancer undergoing radical radiotherapy and staff from the LTHT oncology department. ANALYSIS The primary endpoint analysis will report the number of participants and adherence to the study interventions. Secondary endpoints include continued engagement with study interventions post-treatment. The analysis will focus on descriptive statistics. Thematic analysis of the qualitative data from the ToC study will identify consensus on intervention optimisation and delivery. ETHICS AND DISSEMINATION On 12 May 2021, the Cambridge East Ethics Committee granted ethical approval (21/EE/0048). The study is registered in the National Institute for Health and Care Research (NIHR) portfolio. The results will be disseminated through publication in peer-reviewed scientific journals and presented at conferences. TRIAL REGISTRATION NUMBER NIHR portfolio 48420.

Surv Ophthalmol 2024; 69:93-102. [PMID: 36878359 DOI: 10.1016/j.survophthal.2023.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/24/2023] [Accepted: 02/27/2023] [Indexed: 03/07/2023]
Abstract
Among ocular infections, trachoma is the main cause of blindness. Repeated conjunctival Chlamydia trachomatis infections lead to trichiasis, corneal opacification, and visual impairment. Surgery is often needed to relieve discomfort and preserve vision; however, a high postoperative trachomatous trichiasis (PTT) rate has been observed in various settings. We wanted to know why, whether PTT rates could be reduced, and how to manage the PTT that occurs. We performed a search of the literature. Of 217 papers screened, 59 studies were identified for inclusion as potentially relevant, the majority having been excluded for not directly concerning PTT in humans. Preventing PTT is a major challenge. Only one published trial, the STAR trial in Ethiopia, has reported a cumulative PTT rate <10% one year after surgery. The literature on the management of PTT is sparse. Though no PTT management guidelines are available, high-quality surgery with a low rate of unfavorable outcomes for PTT patients is likely to require enhanced training of a smaller group of highly-skilled surgeons. Based on the surgical complexity and the authors' own experience, the pathway for patients suffering from PTT should be studied further for improvement.

Wu Y, Guo J, Peng W. Application of the IDEAL framework in hepatopancreatobiliary surgery: a review of the literature. Langenbecks Arch Surg 2023; 409:20. [PMID: 38153558 DOI: 10.1007/s00423-023-03211-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 12/20/2023] [Indexed: 12/29/2023]
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
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
BACKGROUND Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. A further therapeutic option may be open abdomen (OA) management with negative peritoneal pressure therapy (NPPT) to remove inflammatory ascites and attenuate the systemic damage from SCIAS, although there are definite risks of leaving the abdomen open whenever it might possibly be closed. This potential therapeutic paradigm is the rationale being assessed in the Closed Or Open after Laparotomy (COOL trial) ( https://clinicaltrials.gov/ct2/show/NCT03163095 ). Initially, the COOL trial received Industry sponsorship; however, this funding mandated the use of a specific trademarked and expensive NPPT device in half of the patients allocated to the intervention (open) arm. In August 2022, the 3 M/Acelity Corporation without consultation but within the terms of the contract canceled the financial support of the trial. Although creating financial difficulty, there is now no restriction on specific NPPT devices and removing a cost-prohibitive intervention creates an opportunity to expand the COOL trial to a truly global basis. This document describes the evolution of the COOL trial, with a focus on future opportunities for global growth of the study. METHODS The COOL trial is the largest prospective randomized controlled trial examining the random allocation of SCIAS patients intra-operatively to either formal closure of the fascia or the use of the OA with an application of an NPPT dressing. Patients are eligible if they have free uncontained intraperitoneal contamination and physiologic derangements exemplified by septic shock OR severely adverse predicted clinical outcomes. The primary outcome is intended to definitively inform global practice by conclusively evaluating 90-day survival. Initial recruitment has been lower than hoped but satisfactory, and the COOL steering committee and trial investigators intend with increased global support to continue enrollment until recruitment ensures a definitive answer. DISCUSSION OA is mandated in many cases of SCIAS such as the risk of abdominal compartment syndrome associated with closure, or a planned second look as for example part of "damage control"; however, improved source control (locally and systemically) is the most uncertain indication for an OA. The COOL trial seeks to expand potential sites and proceed with the evaluation of NPPT agnostic to device, to properly examine the hypothesis that this treatment attenuates systemic damage and improves survival. This approach will not affect internal validity and should improve the external validity of any observed results of the intervention. TRIAL REGISTRATION National Institutes of Health ( https://clinicaltrials.gov/ct2/show/NCT03163095 ).

The unrestricted global effort to complete the COOL trial. World J Emerg Surg 2023; 18:33. [PMID: 37170123 PMCID: PMC10173926 DOI: 10.1186/s13017-023-00500-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 04/13/2023] [Indexed: 05/13/2023] Open
Abstract
BACKGROUND Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. A further therapeutic option may be open abdomen (OA) management with negative peritoneal pressure therapy (NPPT) to remove inflammatory ascites and attenuate the systemic damage from SCIAS, although there are definite risks of leaving the abdomen open whenever it might possibly be closed. This potential therapeutic paradigm is the rationale being assessed in the Closed Or Open after Laparotomy (COOL trial) ( https://clinicaltrials.gov/ct2/show/NCT03163095 ). Initially, the COOL trial received Industry sponsorship; however, this funding mandated the use of a specific trademarked and expensive NPPT device in half of the patients allocated to the intervention (open) arm. In August 2022, the 3 M/Acelity Corporation without consultation but within the terms of the contract canceled the financial support of the trial. Although creating financial difficulty, there is now no restriction on specific NPPT devices and removing a cost-prohibitive intervention creates an opportunity to expand the COOL trial to a truly global basis. This document describes the evolution of the COOL trial, with a focus on future opportunities for global growth of the study. METHODS The COOL trial is the largest prospective randomized controlled trial examining the random allocation of SCIAS patients intra-operatively to either formal closure of the fascia or the use of the OA with an application of an NPPT dressing. Patients are eligible if they have free uncontained intraperitoneal contamination and physiologic derangements exemplified by septic shock OR severely adverse predicted clinical outcomes. The primary outcome is intended to definitively inform global practice by conclusively evaluating 90-day survival. Initial recruitment has been lower than hoped but satisfactory, and the COOL steering committee and trial investigators intend with increased global support to continue enrollment until recruitment ensures a definitive answer. DISCUSSION OA is mandated in many cases of SCIAS such as the risk of abdominal compartment syndrome associated with closure, or a planned second look as for example part of "damage control"; however, improved source control (locally and systemically) is the most uncertain indication for an OA. The COOL trial seeks to expand potential sites and proceed with the evaluation of NPPT agnostic to device, to properly examine the hypothesis that this treatment attenuates systemic damage and improves survival. This approach will not affect internal validity and should improve the external validity of any observed results of the intervention. TRIAL REGISTRATION National Institutes of Health ( https://clinicaltrials.gov/ct2/show/NCT03163095 ).

Development of a conceptual framework for reporting modifications in surgical innovation: scoping review. BJS Open 2023; 7:7145934. [PMID: 37104755 PMCID: PMC10139440 DOI: 10.1093/bjsopen/zrad020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 01/20/2023] [Accepted: 01/28/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Innovative surgical procedures and devices are often modified throughout their development and introduction into clinical practice. A systematic approach to reporting modifications may support shared learning and foster safe and transparent innovation. Definitions of 'modifications', and how they are conceptualized and classified so they can be reported and shared effectively, however, are lacking. This study aimed to explore and summarize existing definitions, perceptions, classifications and views on modification reporting to develop a conceptual framework for understanding and reporting modifications. METHODS A scoping review was conducted in accordance with PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines. Targeted searches and two database searches were performed to identify relevant opinion pieces and review articles. Included were articles relating to modifications to surgical procedures/devices. Data regarding definitions, perceptions and classifications of modifications, and views on modification reporting were extracted verbatim. Thematic analysis was undertaken to identify themes, which informed development of the conceptual framework. RESULTS Forty-nine articles were included. Eight articles included systems for classifying modifications, but no articles reported an explicit definition of modifications. Some 13 themes relating to perception of modifications were identified. The derived conceptual framework comprises three overarching components: baseline data about modifications, details about modifications and impact/consequences of modifications. CONCLUSION A conceptual framework for understanding and reporting modifications that occur during surgical innovation has been developed. This is a first necessary step to support consistent and transparent reporting of modifications, to facilitate shared learning and incremental innovation of surgical procedures/devices. Testing and operationalization is now needed to realize the value of this framework.

The E2R (Emotion, regression, repair) method: A case study of this new pragmatic hypnotherapy technique. Complement Ther Clin Pract 2023; 50:101701.

Abstract
The E2R (Emotion, Regression, Repair) method is a pragmatic and innovative technique for treating psychological complaints. It is the result of the professional experience of two caregivers who have been training medical and paramedical colleagues since 2016 in this method. There is always an Emotion in the symptom that a patient presents. During the trance, the hypnotherapist uses it as a thread for age Regressions, often up to 3 years old. The patient can then identify a situation that triggered an identical experience. They self-reorganizes their emotional experience according to their needs, accompanied step by step by the therapist who follows the protocol of the repair loop. This new emotional reality experienced in trance replaces the factual reality of the previous trauma and reduces or even eliminates the present complaint through an adapted Repair. The E2R method works without taking a prior hypnotizability test. The need for change and the desire to engage in hypnotherapy are the only predispositions required, regardless of the complaint. A case study of a patient with chronic severe insomnia who received four sessions of hypnotherapy using the E2R protocol illustrates this approach and its benefits.

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

Abstract
The foundations of evidence-based practice are the triad of patient values and preferences, healthcare professional experience, and best available evidence, used together to inform clinical decision-making. Within the field of rhabdomyosarcoma, collaborative groups such as the European Paediatric Soft Tissue Sarcoma Group (EpSSG) have worked to develop evidence to support this process. We have explored many of the key research developments within this review, including patient and public involvement, decision-making research, research into areas other than drug development, core outcome sets, reporting and dissemination of research, evidence synthesis, guideline development and clinical decision rules, research of research methodologies, and supporting research in RMS.

Abstract
Robotic systems for head and neck surgery are at different stages of technical development and clinical application. Currently, robotic systems are predominantly used for transoral surgery of the pharynx and larynx. Robotic surgery of the neck, the thyroid, and the middle and inner ear is much less common; however, some oncological and functional outcomes have been reported. This article provides an overview of the current state of robot-assisted head and neck surgery with a special emphasis on patient benefit and postoperative quality of life (QoL). The focus is placed on the role of transoral robotic surgery (TORS) for the resection of oropharyngeal carcinomas. For this application, reported long-term outcomes show functional post-operative advantages for selected oropharyngeal cancer patients after TORS compared to open surgery and primary radiotherapy. Since TORS also plays a significant role in the context of potential therapy de-escalation for HPV-positive oropharyngeal cancer patients, ongoing trials are presented. Regarding the evaluation of the therapeutic benefit and the QoL of cancer patients, special attention has to be paid to the large degree of variability of individual patients' preferences. Influencing factors and tools for a detailed assessment of QoL parameters are therefore detailed at the beginning of this article. Notably, while some robotic systems for ear and skull base surgery are being developed in Europe, TORS systems are mainly used in North America and Asia. In Europe and Germany in particular, transoral laser microsurgery (TLM) is a well-established technology for transoral tumor resection. Future trials comparing TORS and TLM with detailed investigation of QoL parameters are therefore warranted and might contribute to identifying suitable fields for the application of the different techniques.

Abstract
Women treated for breast cancer are facing a lifetime risk of developing lymphedema, which occurs in up to 40% of this population. There is a lack of evidence and limited knowledge regarding the treatment of breast cancer-related lymphedema (BCRL). The aim of this study was to identify, describe, and organize the currently available evidence in the treatment of BCRL. METHODS We conducted an evidence mapping review study according to the methodology proposed by Global Evidence Mapping. We performed a systematic search in Medline, Embase, Central (Cochrane), and Epistemonikos, from 2000-2020. We included studies about all treatment types for BCRL, including surgical and nonsurgical treatment. Results were summarized in narrative and tabular forms. RESULTS A total of 240 studies were included in this mapping review, distributed as follows: 147 experimental studies [102 randomized clinical trials (RCTs) and 45 quasi-experimental clinical trials], 48 observational studies (34 prospective and 14 retrospective studies), and 45 systematic reviews (17 of them with metanalysis). Most of the RCTs were on nonsurgical interventions. Only two RCTs addressed surgical intervention. CONCLUSIONS In the last 20 years, there were an average of 12 publications per year on the treatment of BCRL. Recently this lack of attention has been partially corrected, as the majority were published in the past 5 years. However, most of them were on nonsurgical interventions. Well-designed RCTs on surgery are needed to measure the effectiveness of the applied interventions.

Abstract
OBJECTIVE To identify barriers and facilitators to adoption of a new surgical procedure via an implementation science framework to characterize associated socioemotional, clinical, and decision-making processes. STUDY DESIGN Qualitative study with a semistructured interview approach. SETTING Large tertiary care referral center. METHODS Academic otolaryngologists with at least 2 years of practice were identified and interviewed. Transcripts were thematically coded and separated into steps in the clinical pathway. Synthesis of major themes characterized facilitators and barriers to uptake of a new surgical technique. RESULTS Of 22 otolaryngologists, 19 were interviewed (85% male). They had a median 18 years of practice (interquartile range, 7.8-26.3), and 65% were subspecialty trained. In the decision to implement a new procedure, improving patient outcomes and addressing unmet clinical needs facilitated adoption, whereas costs and adopting profit-driven technologies without improved outcomes were barriers. In patient consults, establishing trust facilitated implementation of new techniques; barriers included participants' hesitation to communicate about the unknowns of a new procedure. Intraoperatively, little change to existing workflow or improved efficiency facilitated adoption, while a substantial learning curve for the new procedure was a barrier. Achieving favorable outcomes and patient satisfaction sustained implementation of new procedures. Too few referrals or indications for the new procedure hindered implementation. CONCLUSION Our study demonstrates that innovation in otolaryngology is often an individual iterative process that providers pursue to improve patients' outcomes. Although models for the oversight of surgical innovation emphasize the need for evidence, obtaining sufficient numbers of providers and patients to generate evidence remains a challenge in specialty surgical practice.

Abstract
BACKGROUND Our current study was performed aimed at determining the efficacy and safety profile of robotic surgery (RS) compared to laparoscopic surgery (LPS) and laparotomy (LT) in the treatment of endometrial cancer on the basis of relevant studies. PATIENTS AND METHODS A systematic literature search was conducted based on appropriate keywords, using the Embase, Cochrane library, as well as PubMed. Our studiers also reviewed the key pertinent sources among the publications and included associated literatures published by June 2021. Odds ratios (ORs), mean difference (MD), as well as 95% confidence interval (95% CI) for each study were measured for further assessment and synthesis of outcomes. RESULTS Thirty studies involving a total of 12,025 patients were eventually included in the current meta-analysis. Compared with LPS, RS could significantly decrease the estimated blood loss, the incidence of intraoperative complications, the length of hospital stay, and the rate of conversion, and increased the rate of readmission. Compared with LT, RS significantly decreased the estimated blood loss, blood transfusion volume, the length of hospital stay, the rate of total, intraoperative and postoperative complications, and the rate of readmission and re-operation, and increased the operative time. CONCLUSION Considering the effects and safety profile of RS in terms of treating endometrial cancer, our study suggest that RS exerts superior outcomes than that of LPS and LT.

Abstract
AIM Transanal total mesorectal excision (TaTME) has been suggested as a potential solution for the resection of challenging mid and low rectal cancer. This relatively complex procedure has been implemented in many centres over the last years, despite the absence of long-term safety data. Recently, concern has arisen because of an increase in local recurrence in the implementation phase. The aim of this study was to assess the correlation between accumulated experience and local recurrences. METHOD An independent clinical researcher performed an external audit of consecutive series of all TaTME procedures in six centres in the Netherlands. Kaplan-Meier estimated local recurrence rates were calculated and multivariate Cox proportional hazards regression analysis performed to assess risk factors for local recurrence. Primary outcome was the local recurrence rate in the initial implementation (cases 1-10), continued adoption (cases 11-40) and prolonged experience (case 41 onward). RESULTS Six hundred and twenty-four consecutive patients underwent TaTME for rectal cancer with a median follow-up of 27 months (range 1-82 months). The estimated 2- and 3-year local recurrence rates were 4.6% and 6.6%, respectively. Cox proportional hazards regression revealed procedural experience to be an independent factor in multivariate analysis next to advanced stage (ycMRF+, pT3-4, pN+) and pelvic sepsis. Corrected analysis projected the 3-year local recurrence rates to be 9.7%, 3.3% and 3.5% for the implementation, continued adoption and prolonged experience cohorts, respectively. CONCLUSION This multicentre study shows a high local recurrence rate (12.5%) after implementation of TaTME which lowers to an acceptable rate (3.4%) when experience increases. Therefore, intensified proctoring and further precautions must be implemented to reduce the unacceptably high risk of local recurrence at units starting this technique.

Abstract
INTRODUCTION Prior in silico simulations of studies of Temporally Feathered Radiation Therapy (TFRT) have demonstrated potential reduction in normal tissue toxicity. This R-IDEAL Stage 1/2A study seeks to demonstrate the first-in-human implementation of TFRT in treating patients with head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS Patients with HNSCC treated with definitive radiation therapy were eligible (70 Gy in 35 fractions) were eligible. The primary endpoint was feasibility of TFRT planning as defined by radiation start within 15 business days of CT simulation. Secondary endpoints included estimates of acute grade 3-5 toxicity. RESULTS The study met its accrual goal of 5 patients. TFRT plans were generated in four of the five patients within 15 business days of CT simulation, therefore meeting the primary endpoint. One patient was not treated with TFRT at the physician's discretion, though the TFRT plan had been generated within sufficient time from the CT simulation. For patients who received TFRT, the median time from CT simulation to radiation start was 10 business days (range 8-15). The average time required for radiation planning was 6 business days. In all patients receiving TFRT, each subplan and every daily fraction was delivered in the correct sequence without error. The OARs feathered included: oral cavity, each submandibular gland, each parotid gland, supraglottis, and posterior pharyngeal wall (OAR pharynx). Prescription dose PTV coverage (>95%) was ensured in each TFRT subplan and the composite TFRT plan. One of five patients developed an acute grade 3 toxicity. CONCLUSIONS This study demonstrates the first-in-human implementation of TFRT (R-IDEAL Stage 1), proving its feasibility in the modern clinical workflow. Additionally, assessments of acute toxicities and dosimetric comparisons to a standard radiotherapy plan were described (R-IDEAL Stage 2a).

Abstract
BACKGROUND The magnitude of association and quality of evidence comparing surgical approaches for lung cancer resection has not been analyzed. This has resulted in conflicting information regarding the relative superiority of the different approaches and disparate opinions on the optimal surgical treatment. We reviewed and systematically analyzed all published data comparing near- (30-d) and long-term mortality for minimally invasive to open surgical approaches for lung cancer. METHODS Comprehensive search of EMBASE, MEDLINE, and the Cochrane Library, from January 2009 to August 2019, was performed to identify the studies and those that passed bias assessment were included in the analysis utilizing propensity score matching techniques. Meta-analysis was performed using random-effects and fixed-effects models. Risk of bias was assessed via the Newcastle-Ottawa Scale and the ROBINS-I tool. The study was registered in PROSPERO (CRD42020150923) prior to analysis. RESULTS Overall, 1382 publications were identified but 19 studies were included encompassing 47,054 patients after matching. Minimally invasive techniques were found to be superior with respect to near-term mortality in early and advanced-stage lung cancer (risk ratio 0.45, 95% confidence interval [CI] 0.21-0.95, I2 = 0%) as well as for elderly patients (odds ratio 0.45, 95% CI 0.31-0.65, I2 = 30%), but did not demonstrate benefit for high-risk patients (odds ratio 0.74, 95% CI 0.06-8.73, I2 = 78%). However, no difference was found in long-term survival. CONCLUSIONS We performed the first systematic review and meta-analysis to compare surgical approaches for lung cancer which indicated that minimally invasive techniques may be superior to thoracotomy in near-term mortality, but there is no difference in long-term outcomes.

Abstract
BACKGROUND Paucity of RCTs of non-drug technologies lead to widespread dependence on non-randomized studies. Relationship between nonrandomized study design attributes and biased estimates of treatment effects are poorly understood. Our purpose was to estimate the bias associated with specific nonrandomized study attributes among studies comparing transcatheter aortic valve implantation with surgical aortic valve replacement for the treatment of severe aortic stenosis. RESULTS We included 6 RCTs and 87 nonrandomized studies. Surgical risk scores were similar for comparison groups in RCTs, but were higher for patients having transcatheter aortic valve implantation in nonrandomized studies. Nonrandomized studies underestimated the benefit of transcatheter aortic valve implantation compared with RCTs. For example, nonrandomized studies without adjustment estimated a higher risk of postoperative mortality for transcatheter aortic valve implantation compared with surgical aortic valve replacement (OR 1.43 [95% CI 1.26 to 1.62]) than high quality RCTs (OR 0.78 [95% CI 0.54 to 1.11). Nonrandomized studies using propensity score matching (OR 1.13 [95% CI 0.85 to 1.52]) and regression modelling (OR 0.68 [95% CI 0.57 to 0.81]) to adjust results estimated treatment effects closer to high quality RCTs. Nonrandomized studies describing losses to follow-up estimated treatment effects that were significantly closer to high quality RCT than nonrandomized studies that did not. CONCLUSION Studies with different attributes produce different estimates of treatment effects. Study design attributes related to the completeness of follow-up may explain biased treatment estimates in nonrandomized studies, as in the case of aortic valve replacement where high-risk patients were preferentially selected for the newer (transcatheter) procedure.

Abstract
INTRODUCTION The number of laparoscopic liver resections undertaken has increased. However, lesions located postero-superiorly are difficult to access. This may be overcome by the novel use of trans-thoracic port(s). Methods for the safe and transparent introduction of new and modified surgical procedures are limited and a summary of these issues, for minimally invasive trans-thoracic liver resections (MITTLR), is lacking. This study aims to understand and summarize technique description, governance procedures, and reporting of outcomes for MITTLR. METHODS A systematic literature search to identify primary studies of all designs describing MITTLR was undertaken. How patients were selected for the new technique was examined. The technical components of MITTLR were identified and summarized to understand technique development over time. Governance arrangements (eg, Institutional Review Board approval) and steps taken to mitigate harm were recorded. Finally, specific outcomes reported across studies were documented. RESULTS Of 2067 screened articles, 16 were included reporting data from 145 patients and 6 countries. Selection criteria for patients was explicitly stated in 2 papers. No studies fully described the technique. Five papers reported ethical approval and 3 gave details of patient consent. No study reported on steps taken to mitigate harm.Technical outcomes were commonly reported, for example, blood loss (15/16 studies), operative time (15/16), and margin status (11/16). Information on patient-reported outcomes and costs were lacking. CONCLUSIONS Technical details and governance procedures were poorly described. Outcomes focussed on short term details alone. Transparency is needed for reporting the introduction of new surgical techniques to allow their safe dissemination.

Robertson RL, Karimuddin A, Phang T, Raval M, Brown C. Transanal versus conventional total mesorectal excision for rectal cancer using the IDEAL framework for implementation. BJS Open 2021; 5:6246778. [PMID: 33889949 PMCID: PMC8062257 DOI: 10.1093/bjsopen/zrab002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Revised: 12/11/2020] [Accepted: 01/01/2021] [Indexed: 01/04/2023] Open
Abstract
Background Transanal total mesorectal excision (TaTME) is an innovative technique for distal rectal cancer dissection. It has been shown to have similar short-term outcomes to conventional open and laparoscopic total mesorectal excision (cTME), but recent studies have raised concern about increased morbidity and local recurrence rates. The aim of this study was to assess outcomes after TaTME versus cTME for rectal cancer. Methods TaTME was implemented in 2014 using IDEAL principles in a single institution. The institution maintains databases for all patients undergoing rectal cancer surgery. This retrospective review compared data collected from all patients who had TaTME with those from a propensity-matched cohort of patients who underwent cTME. The primary outcome was a composite pathological measure combining margin status and quality of total mesorectal excision (TME). Short-term clinical and survival outcomes were also measured. Results Propensity matching created 109 matched pairs for analysis. Nine patients (8.3 per cent) undergoing TaTME had positive margins and/or incomplete TME, compared with 11 (10.5 per cent) undergoing cTME (P = 0.65). There were no significant differences in morbidity between the TaTME and cTME groups, including number of anastomotic leaks (13.8 versus 18.3 per cent; P = 0.37). The estimated 3-year local recurrence-free survival rate was 96.3 per cent in both groups (P = 0.39). Estimated 3-year overall (93.6 per cent for TaTME versus 94.5 per cent for cTME; P = 0.09) and disease-free (88.1 versus 76.1 per cent; P = 0.90) survival rates were similar. Conclusion TaTME provided similar outcomes to cTME for rectal cancer with the application of IDEAL principles.

Abstract
The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement, first published in 2009 [1], was developed in an attempt to increase the clarity, transparency, quality and value of these reports [2]. The 27-item checklist and four-phase flow diagram have become the hallmark of academic rigour in the publication of systematic reviews and meta-analyses, having been cited by over 60,000 papers [3]. These are frequently endorsed by journals in their 'Instructions to Authors' [4]. Developments in the methodology and terminology used when conducting systematic reviews [5], alongside the identification of limitations responsible for poor adherence, such as the use of ambiguous wording [6], have warranted an update to the PRISMA statement. The PRISMA 2020 statement, therefore, is intended to reflect this recent evolution in the identification, selection, appraisal and synthesis of research [7]. Here, we present an interpretive analysis of the updated statement, with a view towards encouraging its adoption by both journals and authors in the pursuit of advancing evidence-based medicine.

Abstract
OBJECTIVE Describe clinical outcomes (eg, postoperative complications, survival) after robotic surgery compared to open or laparoscopic surgery. BACKGROUND Robotic surgery utilization has increased over the years across a wide range of surgical procedures. However, evidence supporting improved clinical outcomes after robotic surgery is limited. METHODS We systematically searched MEDLINE, EMBASE, and the Cochrane Central Register of systematic reviews from inception to January 2019 for systematic reviews describing postoperative outcomes after robotic surgery. We qualitatively described patient outcomes of commonly performed robotic procedures: radical prostatectomy, hysterectomy, lobectomy, thymectomy, rectal resection, partial nephrectomy, distal gastrectomy, Roux-en-Y gastric bypass, hepatectomy, distal pancreatectomy, and cholecystectomy. RESULTS One hundred fifty-four systematic reviews included 336 studies and 18 randomized controlled trials reporting on patient outcomes after robotic compared to laparoscopic or open procedures. Data from the randomized controlled trials demonstrate that robotic-assisted radical prostatectomy offered fewer biochemical recurrence and improvement in quality of recovery and pain scores only up to 6 weeks postoperatively compared to open radical prostatectomy. When compared to laparoscopic prostatectomy, robotic surgery offered improved urinary and sexual functions. Robotic surgery for endometrial cancer had fewer conversion to open compared to laparoscopic. Otherwise, robotic surgery outcomes were similar to conventional surgical approaches for other procedures except for radical hysterectomy where minimally invasive approaches may result in patient harm compared to open approach. CONCLUSION Robotic surgery has been widely incorporated into practise despite limited supporting evidence. More rigorous research focused on patient-important benefits is needed before further expansion of robotic surgery.

BMJ SURGERY, INTERVENTIONS, & HEALTH TECHNOLOGIES 2021; 3:e000050. [PMID: 35047799 PMCID: PMC8647616 DOI: 10.1136/bmjsit-2020-000050] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 09/09/2020] [Accepted: 10/19/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Approximately £1130 billion was invested in research worldwide in 2016, and 9.6% of this was on biomedical research. However, about 85% of biomedical research investment is wasted. The Lancet published a series to identify five categories relating to research waste and in 2014. Some categories of research waste in surgery are avoidable by complying with the Idea, Development, Exploration, Assessment, Long-term follow-up (IDEAL) framework for it enables researchers to design, conduct and report surgical studies robustly and transparently. This review aims to examine the extent to which surgical studies adhered to the IDEAL framework and estimate the amount of overall research waste that could be avoided if compliance was improved. Methods We will search for potential studies published in English and between 1 January 2018 and 31 December 2018 via PubMed. Teams of paired reviewers will screen titles, abstracts and full texts independently. Two researchers will extract data from each paper. Data will be collected about general information and specialised information in each stage, and our IDEAL Compliance Appraisal tool will be used to analyse included studies. Descriptive statistics and χ2 or Fisher’s exact tests for comparisons will be presented. Discussion Our study will provide important information about whether compliance with the specific IDEAL Recommendations has reduced research waste in surgical and therapeutic device studies. And we will identify particular key aspects that are worse and need to focus on improving those in future education.

SAGE Open Med 2020; 8:2050312120977116. [PMID: 33329894 PMCID: PMC7720299 DOI: 10.1177/2050312120977116] [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: 08/18/2020] [Accepted: 11/06/2020] [Indexed: 12/03/2022] Open
Abstract
Objectives: High-quality research has a tangible impact on patient care and should inform all medical decision-makings. Appraising and benchmarking of research is necessary in evidence-based medicine and allocation of funding. The aim of this review is to demonstrate how evidence may be gathered by quantifying the amount and type of research by a group of surgeons over a 20-year period. Methods: Members of the Colorectal Surgical Society of Australia and New Zealand were identified in April 2020. A search of the Scopus database was conducted to quantify each surgeon’s research output from 1999 to 2020. Authorship details such as the Hirsch index and number of papers published were recorded, as were publication-related details. Results: 226 colorectal surgeons were included for analysis, producing a total of 5053 publications. The most frequent colorectal topics were colorectal cancer (32%, n = 1617 of all publications), followed by pelvic floor disorders (4.3%, n = 217) and inflammatory bowel disease (3.5%, n = 177). 56% (n = 2830) of all publications were case series audits (21%, n = 1061), expert opinion pieces (20%, n = 1011) and cohort studies (15%, n = 758). 7% (n = 354) were randomised control or non-randomised control trials, 3% (n = 152) were systematic reviews and 1% (n = 50) were meta-analyses. The top 10% (n = 23) of authors accounted for more than half (54%, n = 2729) of manuscripts published. Conclusion: Australasian colorectal surgeons made a significant contribution to the medical literature over the past 20 years and the number of publications is increasing over time. A greater output of higher-level evidence research is needed. This information may be used to better allocate researcher funding and grants for future projects.

Abstract
BACKGROUND Dissemination of new surgical technology is a major contributor to healthcare spending growth. Accountable care organization (ACO) policy aims to control spending while maintaining quality. As a result, ACOs provide incentive for hospitals to selectively adopt newer procedures with high value. STUDY DESIGN We conducted a retrospective cohort study using a 20% sample of national Medicare claims from 2010 to 2015. We identified hospitals that performed 1 of 6 sets of procedures: abdominal aortic aneurysm repair, aortic valve replacement, carotid endarterectomy or stent, lung lobectomy, colectomy, and prostatectomy. We identified hospitals participating in a Medicare Shared Savings Program ACO and a set of matched non-ACO control hospitals. We used a difference-in-differences approach to compare rate of surgical treatment and use of newer surgical technology for each set of procedures in ACO and non-ACO hospitals. RESULTS We included 707 ACO-hospitals and 1,770 control hospitals. ACO hospitals performed surgery for carotid stenosis at a lower rate than non-ACO hospitals. There was no difference in the rate of surgical treatment for all other procedure sets. ACO hospitals were less likely to use an endovascular approach for abdominal aortic aneurysm repair (85.2% vs 88.2%, p < 0.001) and more likely to use a minimally invasive approach for lung lobectomy (42.2% vs 34.7%, p = 0.004) than non-ACO hospitals. In difference-in-differences analysis, ACO participation was not associated with any significant difference in use of surgical care for any of the 6 procedure sets, nor with any significant difference in use of newer surgical technology. CONCLUSIONS Despite ACO policy incentives to selectively adopt newer surgical technology, ACO participation was not associated with differences in rate of surgery or use of newer surgical technology for 6 major surgical procedures.

Abstract
BACKGROUND Frameworks used in research impact evaluation studies vary widely and it remains unclear which methods are most appropriate for evaluating research impact in the field of surgical research. Therefore, we aimed to identify and review the methods used to assess the impact of surgical intervention trials on healthcare and to identify determinants for surgical impact. METHODS We searched journal databases up to March 10, 2020 for papers assessing the impact of surgical effectiveness trials on healthcare. Two researchers independently screened the papers for eligibility and performed a Risk of Bias assessment. Characteristics of both impact papers and trial papers were summarized. Univariate analyses were performed to identify determinants for finding research impact, which was defined as a change in healthcare practice. RESULTS Sixty-one impact assessments were performed in 37 included impact papers. Some surgical trial papers were evaluated in more than one impact paper, which provides a total of 38 evaluated trial papers. Most impact papers were published after 2010 (n = 29). Medical records (n = 10), administrative databases (n = 22), and physician's opinion through surveys (n = 5) were used for data collection. Those data were analyzed purely descriptively (n = 3), comparing data before and after publication (n = 29), or through time series analyses (n = 5). Significant healthcare impact was observed 49 times and more often in more recent publications. Having impact was positively associated with using medical records or administrative databases (ref.: surveys), a longer timeframe for impact evaluation and more months between the publication of the trial paper and the impact paper, data collection in North America (ref.: Europe), no economic evaluation of the intervention, finding no significant difference in surgical outcomes, and suggesting de-implementation in the original trial paper. CONCLUSIONS AND IMPLICATIONS Research impact evaluation receives growing interest, but still a small number of impact papers per year was identified. The analysis showed that characteristics of both surgical trial papers and impact papers were associated with finding research impact. We advise to collect data from either medical records or administrative databases, with an evaluation time frame of at least 4 years since trial publication.

Abstract
Background Transanal total mesorectal excision (TaTME) has been proposed as an approach in patients with mid and low rectal cancer. The TaTME procedure has been introduced in the Netherlands in a structured training pathway, including proctoring. This study evaluated the local recurrence rate during the implementation phase of TaTME. Methods Oncological outcomes of the first ten TaTME procedures in each of 12 participating centres were collected as part of an external audit of procedure implementation. Data collected from a cohort of patients treated over a prolonged period in four centres were also collected to analyse learning curve effects. The primary outcome was the presence of locoregional recurrence. Results The implementation cohort of 120 patients had a median follow up of 21·9 months. Short‐term outcomes included a positive circumferential resection margin rate of 5·0 per cent and anastomotic leakage rate of 17 per cent. The overall local recurrence rate in the implementation cohort was 10·0 per cent (12 of 120), with a mean(s.d.) interval to recurrence of 15·2(7·0) months. Multifocal local recurrence was present in eight of 12 patients. In the prolonged cohort (266 patients), the overall recurrence rate was 5·6 per cent (4·0 per cent after excluding the first 10 procedures at each centre). Conclusion TaTME was associated with a multifocal local recurrence rate that may be related to suboptimal execution rather than the technique itself. Prolonged proctoring, optimization of the technique to avoid spillage, and quality control is recommended.

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

Is the Recommendation of a Pelvic Lymphadenectomy in Conjunction with Radical Prostatectomy in Prostate Cancer Patients Justified? Report from a Multidisciplinary Expert Panel Meeting. Adv Ther 2020; 37:213-224.

Abstract
INTRODUCTION Pelvic lymphadenectomy (pLA) in prostate cancer (PCa) is one of the most common uro-oncologic surgical procedures. An increased complication rate is accompanied by unproven oncologic benefit. Extent of pLA and mechanisms of metastasis are discussed controversially. We aimed to explore evidence and knowledge gaps in pLA and mechanisms of metastasis in PCa and to develop further steps to clarify oncologic benefits through an expert panel. METHODS A multidisciplinary expert meeting was initiated, compiling available facts on pLA and mechanisms of metastasis in PCa. Questions and hypotheses were formulated. The resulting protocol was modeled on priority and consistency in four anonymized voting rounds using the Delphi method (March 2018-June 2018). RESULTS The oncologic benefit of pLA in PCa is still unclear. Results of randomized trials (RCTs) are pending. Extent and techniques of pLA are differently applied and inconsistently recommended by the guidelines as well as the indication for pLA. Different growth rates for the primaries and metastases and different survival curves for lymph node and organ metastasis at diagnosis argue against metastasis originating from positive nodes. However, results from clinical and basic research support this opportunity in PCa. CONCLUSIONS The RCTs required to clarify the estimated low oncologic benefit of pLA prove to be difficult because of the great effort (e.g., high case number). Establishing a network of treatment centers for implementation of high-quality cohort studies could be an alternative approach. Future studies with larger panels and international participants based on the presented feasibility should be launched to set this process in motion. Until valid data are available, benefits and harms of pLA should be weighted under consideration of low-invasive techniques (e.g., sentinel pLA).

Abstract
Knee Surgery is one of the most commonly performed orthopedic procedures, and a rapidly evolving area of research. A bibliographic analysis was conducted to explore the characteristics of the top 50 most cited articles in knee surgery. The Web of Science Core Collection Database was used to search for Knee AND Surgery, further refined for orthopedic surgery, yielding 1,660 articles. After inclusion and exclusion criteria were applied, the top 50 cited articles were statistically and thematically analyzed. Year of publication ranged from 1982 to 2014. The highest volume of research came from USA, with the Journal of Bone and Joint Surgery having the highest number of papers in the top 50. The most common theme of research was Knee Arthroplasty Outcomes. Our study elucidates trends and popular areas of research in the field of knee surgery, and provides researchers with an overview of areas to focus, where there is scope for high-impact original research.

Ethical considerations in conducting surgical research in severe complicated intra-abdominal sepsis. World J Emerg Surg 2019; 14:39. [PMID: 31404221 PMCID: PMC6683332 DOI: 10.1186/s13017-019-0259-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 07/24/2019] [Indexed: 12/13/2022] Open
Abstract
Background Severe complicated intra-abdominal sepsis (SCIAS) has high mortality, thought due in part to progressive bio-mediator generation, systemic inflammation, and multiple organ failure. Treatment includes early antibiotics and operative source control. At surgery, open abdomen management with negative-peritoneal-pressure therapy (NPPT) has been hypothesized to mitigate MOF and death, although clinical equipoise for this operative approach exists. The Closed or Open after Laparotomy (COOL) study (https://clinicaltrials.gov/ct2/show/NCT03163095) will prospectively randomize eligible patients intra-operatively to formal abdominal closure or OA with NPTT. We review the ethical basis for conducting research in SCIAS. Main body Research in critically ill incapacitated patients is important to advance care. Conducting research among SCIAS is complicated due to the severity of illness including delirium, need for emergent interventions, diagnostic criteria confirmed only at laparotomy, and obtundation from anaesthesia. In other circumstances involving critically ill patients, clinical experts have worked closely with ethicists to apply principles that balance the rights of patients whilst simultaneously permitting inclusion in research. In Canada, the Tri-Council Policy Statement-2 (TCPS-2) describes six criteria that permit study enrollment and randomization in such situations: (a) serious threat to the prospective participant requires immediate intervention; (b) either no standard efficacious care exists or the research offers realistic possibility of direct benefit; (c) risks are not greater than that involved in standard care or are clearly justified by prospect for direct benefits; (d) prospective participant is unconscious or lacks capacity to understand the complexities of the research; (e) third-party authorization cannot be secured in sufficient time; and (f) no relevant prior directives are known to exist that preclude participation. TCPS-2 criteria are in principle not dissimilar to other (inter)national criteria. The COOL study will use waiver of consent to initiate enrollment and randomization, followed by surrogate or proxy consent, and finally delayed informed consent in subjects that survive and regain capacity. Conclusions A delayed consent mechanism is a practical and ethical solution to challenges in research in SCIAS. The ultimate goal of consent is to balance respect for patient participants and to permit participation in new trials with a reasonable opportunity for improved outcome and minimal risk of harm.

Abstract
BACKGROUND RCTs in surgery are challenging owing to well established methodological issues. Well designed pilot and feasibility studies (PFS) may help overcome such issues to inform successful main trial design and conduct. This study aimed to analyse protocols of UK-funded studies to explore current use of PFS in surgery and identify areas for practice improvement. METHODS PFS of surgical interventions funded by UK National Institute for Health Research programmes from 2005 to 2015 were identified, and original study protocols and associated publications sourced. Data extracted included study design characteristics, reasons for performing the work including perceived uncertainties around conducting a definitive main trial, and whether the studies had been published. RESULTS Thirty-five surgical studies were identified, of which 29 were randomized, and over half (15 of 29) included additional methodological components (such as qualitative work examining recruitment, and participant surveys studying current interventions). Most studies focused on uncertainties around recruitment (32 of 35), with far fewer tackling uncertainties specific to surgery, such as intervention stability, implementation or delivery (10 of 35). Only half (19 of 35) had made their results available publicly, to date. CONCLUSION The full potential of pretrial work to inform and optimize definitive surgical studies is not being realized.

Abstract
OBJECTIVE The objective of this study was to provide insight into current practice in planning for, and acknowledging, the presence of learning and clustering effects, by treating center and surgeon, when developing randomized surgical trials. STUDY DESIGN AND SETTING Complexities associated with delivering surgical interventions, such as clustering effects, by center or surgeon, and surgical learning should be considered at trial design. Main trial publications, within the wider literature, under-report these considerations. Funded applications, within a 4-year period, from a leading UK funding body were searched. Data were extracted on considerations for learning and clustering effects and the driver, funder, or applicant, behind these. RESULTS Fifty trials were eligible. Managing learning through establishing predefined center and surgeon credentials was common. One planned exploratory analysis of learning within center, and two within surgeon. Clustering, by site and surgeon, was often managed through stratifying randomization, with 81% and 60%, respectively, also planning to subsequently adjust analysis. One-third of responses to referees contained funder led changes accounting for learning and/or clustering. CONCLUSION This review indicates that researchers do consider impact of learning and clustering, by center and surgeon, during trial development. Furthermore, the funder is identified as a potential driver of considerations.
