Surgical Handover Core Outcome Measures (SH-CORE): a protocol for the development of a core outcome set for trials in surgical handover.

BACKGROUND: Surgical handover is associated with a significant risk of care failures. Existing research displays methodological deficiencies and little consensus on the outcomes that should be used to evaluate interventions in this area. This paper reports a protocol to develop a core outcome set (COS) to support standardisation, comparability, and evidence synthesis in future studies of surgical handover between doctors. METHODS: This study adheres to the Core Outcome Measures in Effectiveness Trials (COMET) initiative guidance for COS development, including the COS-Standards for Development (COS-STAD) and Reporting (COS-STAR) recommendations. It has been registered prospectively on the COMET database and will be led by an international steering group that includes surgical healthcare professionals, researchers, and patient and public partners. An initial list of reported outcomes was generated through a systematic review of interventions to improve surgical handover (PROSPERO: CRD42022363198). Findings of a qualitative evidence synthesis of patient and public perspectives on handover will augment this list, followed by a real-time Delphi survey involving all stakeholder groups. Each Delphi participant will then be invited to take part in at least one online consensus meeting to finalise the COS. ETHICS AND DISSEMINATION: This study was approved by the Royal College of Surgeons in Ireland (RCSI) Research Ethics Committee (202309015, 7th November 2023). Results will be presented at surgical scientific meetings and submitted to a peer-reviewed journal. A plain English summary will be disseminated through national websites and social media. The authors aim to integrate the COS into the handover curriculum of the Irish national surgical training body and ensure it is shared internationally with other postgraduate surgical training programmes. Collaborators will be encouraged to share the findings with relevant national health service functions and national bodies. DISCUSSION: This study will represent the first published COS for interventions to improve surgical handover, the first use of a real-time Delphi survey in a surgical context, and will support the generation of better-quality evidence to inform best practice.

Assessing current handover practices in surgery: A survey of non-consultant hospital doctors in Ireland.

BACKGROUND: Handovers of care are potentially hazardous moments in the patient journey and can lead to harm if conducted poorly. Through a national survey of surgical doctors in Ireland, this paper assesses contemporary surgical handover practices and evaluates barriers and facilitators of effective handover. METHODS: After ethical approval and pre-testing with a representative sample, a cross-sectional, online survey was distributed to non-consultant hospital doctors (NCHDs) working in the Republic of Ireland. A mixed-methods approach was used, combining data using triangulation design. MAIN FINDINGS: A total of 201 responses were received (18.5%). Most participants were senior house officers or senior registrars (49.7% and 37.3%). Most people (85.1%) reported that information received during handover was missing or incorrect at least some of the time. One-third of respondents reported that a near-miss had occurred as a result of handover within the past three months, and handover-related errors resulted in minor (16.9%), moderate (4.9%), or major (1.5%) harm. Only 11.4% had received any formal training. Reported barriers to handover included negative attitudes, a lack of institutional support, and competing clinical activities. Facilitators included process standardisation, improved access to resources, and staff engagement. CONCLUSIONS: Surgical NCHDs working in Irish hospitals reported poor compliance with international best practice for handover and identified potential harms. Process standardisation, appropriate staff training, and the provision of necessary handover-related resources is required at a national level to address this significant patient safety concern.

Management Strategies for Malignant Left-Sided Colonic Obstruction: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials and Propensity Score Matching Studies.

BACKGROUND: The optimal treatment strategy for left-sided malignant colonic obstruction remains controversial. Emergency colonic resection has been the standard of care; however, self-expanding metallic stenting as a bridge to surgery may offer short-term advantages, although oncological concerns exist. Decompressing stoma may provide a valid alternative, with limited evidence. OBJECTIVE: To perform a systematic review and Bayesian arm random-effects model network meta-analysis comparing the approaches for management of malignant left-sided colonic obstruction. DATA SOURCES: A systematic review of PubMed, Embase, Cochrane Library, and Google Scholar databases was conducted from inception to August 22, 2023. STUDY SELECTION: Randomized controlled trials and propensity score-matched studies. INTERVENTIONS: Emergency colonic resection, self-expanding metallic stent, and decompressing stoma. MAIN OUTCOME MEASURES: Oncologic efficacy, morbidity, successful minimally invasive surgery, primary anastomosis, and permanent stoma rates. RESULTS: Nineteen of 5225 articles identified met our inclusion criteria. Stenting (risk ratio 0.57; 95% credible interval, 0.33-0.79) and decompressing stomas (risk ratio 0.46, 95% credible interval: 0.18-0.92) resulted in a significant reduction in the permanent stoma rate. Stenting facilitated minimally invasive surgery more frequently (risk ratio 4.10; 95% credible interval, 1.45-13.13) and had lower overall morbidity (risk ratio 0.58; 95% credible interval, 0.35-0.86). A pairwise analysis of primary anastomosis rates showed increased stenting (risk ratio 1.40; 95% credible interval, 1.31-1.49) compared with emergency resection. There was a significant decrease in the 90-day mortality with stenting (risk ratio 0.63; 95% credible interval, 0.41-0.95) compared with resection. There were no differences in disease-free and overall survival rates, respectively. LIMITATIONS: There is a lack of randomized controlled trials and propensity score matching data comparing short-term and long-term outcomes for diverting stomas compared to self-expanding metallic stents. Two trials compared self-expanding metallic stents and diverting stomas in left-sided malignant colonic obstruction. CONCLUSIONS: This study provides high-level evidence that a bridge-to-surgery strategy is safe for the management of left-sided malignant colonic obstruction and may facilitate minimally invasive surgery, increase primary anastomosis rates, and reduce permanent stoma rates and postoperative morbidity compared with emergency colonic resection.

Performance in Irish Selection and Future Performance in Surgical Training.

Importance: Selection processes for surgical training should aim to identify candidates who will become competent independent practitioners and should aspire to high standards of reliability and validity. Objective: To determine the association between measured candidate factors at the time of an Irish selection and assessment outcomes in surgical training, examined via rate of progression to Higher Specialist Training (HST), attrition rates, and performance as assessed through a multimodal framework of workplace-based and simulation-based assessments. Design, Setting, and Participants: This retrospective observational cohort study included data from all successful applicants to the Royal College of Surgeons in Ireland (RCSI) national Core Surgical Training (CST) program. Participants included all trainees recruited to dedicated postgraduate surgical training from 2016 to 2020. These data were analyzed from July 11, 2016, through July 10, 2022. Exposures: Selection decisions were based on a composite score that was derived from technical aptitude assessments, undergraduate academic performance, and a 4-station multiple mini-interview. Main outcomes and measures: Assessment data, attrition rates, and rates of progression to HST were recorded for each trainee. CST performance was assessed using workplace-based and simulation-based technical and nontechnical skill assessments. Potential associations between selection and assessment measures were explored using Pearson correlation, logistic regression, and multiple linear-regression analyses. Results: Data were available for 303 trainees. Composite scores were positively associated with progression to HST (odds ratio [OR], 1.09; 95% CI, 1.05-1.13). There was a weak positive correlation, ranging from 0.23 to 0.34, between scores and performance across all CST assessments. Multivariable linear regression analysis showed technical aptitude scores at application were associated with future operative performance assessment scores, both in the workplace (ß = 0.31; 95% CI, 0.14-0.48) and simulated environments (ß = 0.57; 95% CI, 0.33-0.81). There was evidence that the interpersonal skills interview station was associated with future performance in simulated communication skill assessments (ß = 0.55; 95% CI, 0.22-0.87). Conclusions and Relevance: In this study, performance at the time of Irish national selection, measured across technical and nontechnical domains in a multimodal fashion, was associated with future performance in the workplace and in simulated environments. Future studies will be required to explore the consequential validity of selection, including potential unintended effects of selection and ranking on candidate performance.

Daily handover in surgery: systematic review and a novel taxonomy of interventions and outcomes.

BACKGROUND: Poor-quality handovers lead to adverse outcomes for patients; however, there is a lack of evidence to support safe surgical handovers. This systematic review aims to summarize the interventions available to improve end-of-shift surgical handover. A novel taxonomy of interventions and outcomes and a modified quality assessment tool are also described. METHODS: Ovid MEDLINE®, PubMed, Embase, and Cochrane databases were searched for articles up to April 2023. Comparative studies describing interventions for daily in-hospital surgical handovers between doctors were included. Studies were grouped according to their interventions and outcomes. RESULTS: In total, 6139 citations were retrieved, and 41 studies met the inclusion criteria. The total patient sample sizes in the control and intervention groups were 11 946 and 11 563 patients, respectively. Most studies were pre-/post-intervention cohort studies (92.7%), and most (73.2%) represented level V evidence. The mean quality assessment score was 53.4% (17.1). A taxonomy of handover interventions and outcomes was developed, with interventions including handover tools, process standardization measures, staff education, and the use of mnemonics. More than 25% of studies used a document as the only intervention. Overall, 55 discrete outcomes were assessed in four categories including process (n = 27), staff (n = 14), patient (n = 12) and system-level (n = 2) outcomes. Significant improvements were seen in 51.8%, 78.5%, 58.3% (n = 9761 versus 9312 patients) and 100% of these outcomes, respectively. CONCLUSIONS: Most publications demonstrate that good-quality surgical handover improves outcomes and many interventions appear to be effective; however, studies are methodologically heterogeneous. These novel taxonomies and quality assessment tool will help standardize future studies.

Generating a Prioritized List of Operative Procedures for Simulation-based Assessment of General Surgery Trainees Through Consensus.

OBJECTIVE: To develop appropriate content for high-stakes simulation-based assessments of operative competence in general surgery training through consensus. BACKGROUND: Valid methods of summative operative competence assessment are required by competency-based training programs in surgery. METHOD: An online Delphi consensus study was conducted. Procedures were derived from the competency expectations outlined by the Joint Committee on Surgical Training Curriculum 2021, and subsequent brainstorming. Procedures were rated according to their perceived importance, perceived procedural risk, how frequently they are performed, and simualtion feasibility by a purposive sample of 30 surgical trainers and a 5-person steering group. A modified Copenhagen Academy for Medical Education and Simulation Needs Assessment Formula was applied to the generated data to produce ranked procedural lists, which were returned to participants for re-prioritization. RESULTS: Prioritized lists were generated for simulation-based operative competence assessments at 2 key stages of training; the end of 'phase 2' prior to the development of a sub-specialty interest, and the end of 'phase 3', that is, end-of-training certification. A total of 21 and 16 procedures were deemed suitable for assessments at each of these stages, respectively. CONCLUSIONS: This study describes a national needs assessment approach to content generation for simulation-based assessments of operative competence in general surgery using Delphi consensus methodology. The prioritized procedural lists generated by this study can be used to further develop operative skill assessments for use in high-stakes scenarios, such as trainee progression, entrustment, and end-of-training certification, before subsequent validity testing.

Radiogenomics: Contemporary Applications in the Management of Rectal Cancer.

Radiogenomics, a sub-domain of radiomics, refers to the prediction of underlying tumour biology using non-invasive imaging markers. This novel technology intends to reduce the high costs, workload and invasiveness associated with traditional genetic testing via the development of 'imaging biomarkers' that have the potential to serve as an alternative 'liquid-biopsy' in the determination of tumour biological characteristics. Radiogenomics also harnesses the potential to unlock aspects of tumour biology which are not possible to assess by conventional biopsy-based methods, such as full tumour burden, intra-/inter-lesion heterogeneity and the possibility of providing the information of tumour biology longitudinally. Several studies have shown the feasibility of developing a radiogenomic-based signature to predict treatment outcomes and tumour characteristics; however, many lack prospective, external validation. We performed a systematic review of the current literature surrounding the use of radiogenomics in rectal cancer to predict underlying tumour biology.

Obesity, Sarcopenia and Myosteatosis: Impact on Clinical Outcomes in the Operative Management of Crohn's Disease.

BACKGROUND: Obesity, sarcopenia, and myosteatosis in inflammatory bowel disease may confer negative outcomes, but their prevalence and impact among patients with Crohn's disease (CD) have not been systematically studied. The aim of this study was to assess nutritional status and body composition among patients undergoing resectional surgery for CD and determine impact on operative outcomes. METHODS: Consecutive patients with CD undergoing resection from 2000 to 2018 were studied. Total, subcutaneous, and visceral fat areas and lean tissue area (LTA) and intramuscular adipose tissue (IMAT) were determined preoperatively by computed tomography at L3 using SliceOmatic (Tomovision, Canada). Univariable and multivariable linear, logistic, and Cox proportional hazards regression were performed. RESULTS: One hundred twenty-four consecutive patients were studied (ileocolonic disease 53%, n = 62, biologic therapy 34.4% n = 43). Mean fat mass was 22.7 kg, with visceral obesity evident in 23.9% (n = 27). Increased fat stores were associated with reduced risk of emergency presentation but increased corticosteroid use (ß 9.09, standard error 3.49; P = .011). Mean LBM was 9.9 kg. Sarcopenia and myosteatosis were associated with impaired baseline nutritional markers. Myosteatosis markers IMAT (P = .002) and muscle attenuation (P = .0003) were associated with increased grade of complication. On multivariable analysis, IMAT was independently associated with increased postoperative morbidity (odds ratio [OR], 1.08; 95% confidence interval (CI), 1.01-1.16; P = .037) and comprehensive complications index (P = .029). Measures of adiposity were not associated with overall morbidity; however, increased visceral fat area independently predicted venous thromboembolism (OR, 1.02; 95% CI, 1.00-1.05; P = .028), and TFA was associated with increased wound infection (OR, 1.00; 95% CI, 1.00-1.01; P = .042) on multivariable analysis. CONCLUSION: Myosteatosis is associated with nutritional impairment and predicts increased overall postoperative morbidity following resection for CD. Despite its association with specific increased postoperative risks, increased adiposity does not increase overall morbidity, reflecting preservation of nutritional status and relatively more quiescent disease phenotype. Impaired muscle mass and function represent an appealing target for patient optimization to improve outcomes in the surgical management of CD.

Myosteatosis was predictive of postoperative morbidity following surgery for Crohn's Disease. Increased adiposity does not increase overall morbidity, reflecting a more quiescent disease phenotype. Obesity, myosteatosis, and sarcopenia represent appealing targets for patient optimization to improve outcomes surgical outcomes in Crohn's Disease.

Assessing operative competence in core surgical training: A reliability analysis.

BACKGROUND: This study quantifies the number of observations required to reliably assess the operative competence of Core Surgical Trainees (CSTs) in Ireland, using the Supervised Structured Assessment of Operative Performance (SSAOP) tool. METHODS: SSAOPs (April 2016-February 2021) were analysed across a mix of undifferentiated procedures, as well as for three commonly performed general surgery procedures in CST: appendicectomy, abdominal wall hernia repair, and skin/subcutaneous lesion excision. Generalizability and Decision studies determined the number of observations required to achieve dependability indices ≥0.8, appropriate for use in high-stakes assessment. RESULTS: A total of 2,294 SSAOPs were analysed. Four assessors, each observing 10 cases, can generate scores sufficiently reliable for use in high-stakes assessments. Focusing on a selection of core procedures yields more favourable reliability indices. CONCLUSION: Trainers should conduct repeated assessments across a smaller number of procedures to improve reliability. Programs should increase the assessor mix to yield sufficient dependability indices for high-stakes assessment.

A National Needs Assessment in Simulation Based Training in Vascular Surgery.

OBJECTIVES: The aim of this research was to ascertain the highest need areas for vascular simulation, in order to tailor training for the highest impact. DESIGN, PARTICIPANTS AND SETTING: A needs assessment was conducted according to best practices using the Delphi method. All consultant vascular surgeons/trainers in the training jurisdiction (n=33) were approached through an independent intermediary to contribute and generate a prioritized list of procedures for training. The research team were blinded to participant identities. Three rounds were conducted according to the Delphi process and scored according to the Copenhagen Needs Assessment Formula (CAMES-NAF). RESULTS: A final list of 34 vascular procedures was selected and prioritized by surgical trainers. Principles of arterial repair and endarterectomy/patching were considered the highest priority. Complex major interventions such as open abdominal aortic aneurysm (AAA) repair, carotid endarterectomy, and endovascular aortic repair (EVAR) consistently ranked higher than rarer, such as first rib resection and more basic procedures, such as foam injection for varicose veins. Major lower limb amputations typically ranked lower overall compared to arterial interventions. Surgical trainers generally agreed with the ranking according to the CAMES-NAF. There was some disagreement for a select few procedures such as iliac stenting (which rose 13 places) and open radial artery exposure (which fell 6 places) on subsequent iterations. CONCLUSIONS: Core operative principles and common major operative cases should remain the priority for vascular technical skills training. Other procedures which may be less invasive, but have the potential for major complications should also not be overlooked. In designing simulators the main focus should center on specific skill acquisition for commonly performed major procedures and management of the recognized potential complications. Lower limb amputations are considered adequately taught in clinical practice, or are too challenging to simulate in simulator models apart from cadaveric models.

Mechanical bowel preparation and antibiotics in elective colorectal surgery: network meta-analysis.

BACKGROUND: The use of intravenous antibiotics at anaesthetic induction in colorectal surgery is the standard of care. However, the role of mechanical bowel preparation, enemas, and oral antibiotics in surgical site infection, anastomotic leak, and other perioperative outcomes remains controversial. The aim of this study was to determine the optimal preoperative bowel preparation strategy in elective colorectal surgery. METHODS: A systematic review and network meta-analysis of RCTs was performed with searches from PubMed/MEDLINE, Scopus, Embase, and the Cochrane Central Register of Controlled Trials from inception to December 2022. Primary outcomes included surgical site infection and anastomotic leak. Secondary outcomes included 30-day mortality rate, ileus, length of stay, return to theatre, other infections, and side effects of antibiotic therapy or bowel preparation. RESULTS: Sixty RCTs involving 16 314 patients were included in the final analysis: 3465 (21.2 per cent) had intravenous antibiotics alone, 5268 (32.3 per cent) had intravenous antibiotics + mechanical bowel preparation, 1710 (10.5 per cent) had intravenous antibiotics + oral antibiotics, 4183 (25.6 per cent) had intravenous antibiotics + oral antibiotics + mechanical bowel preparation, 262 (1.6 per cent) had intravenous antibiotics + enemas, and 1426 (8.7 per cent) had oral antibiotics + mechanical bowel preparation. With intravenous antibiotics as a baseline comparator, network meta-analysis demonstrated a significant reduction in total surgical site infection risk with intravenous antibiotics + oral antibiotics (OR 0.47 (95 per cent c.i. 0.32 to 0.68)) and intravenous antibiotics + oral antibiotics + mechanical bowel preparation (OR 0.55 (95 per cent c.i. 0.40 to 0.76)), whereas oral antibiotics + mechanical bowel preparation resulted in a higher surgical site infection rate compared with intravenous antibiotics alone (OR 1.84 (95 per cent c.i. 1.20 to 2.81)). Anastomotic leak rates were lower with intravenous antibiotics + oral antibiotics (OR 0.63 (95 per cent c.i. 0.44 to 0.90)) and intravenous antibiotics + oral antibiotics + mechanical bowel preparation (OR 0.62 (95 per cent c.i. 0.41 to 0.94)) compared with intravenous antibiotics alone. There was no significant difference in outcomes with mechanical bowel preparation in the absence of intravenous antibiotics and oral antibiotics in the main analysis. CONCLUSION: A bowel preparation strategy with intravenous antibiotics + oral antibiotics, with or without mechanical bowel preparation, should represent the standard of care for patients undergoing elective colorectal surgery.

Comparison of Restorative Proctocolectomy with and Without Defunctioning Loop Ileostomy in Patients with Ulcerative Colitis: A Systematic Review and Meta-analysis.

BACKGROUND: Restorative proctocolectomy [RPC] without a defunctioning loop ileostomy [DLI] in patients with ulcerative colitis [UC] remains controversial. AIM: To compare safety and efficacy of RPC with and without DLI in patients exclusively with UC. METHODS: A systematic review was performed according to PRISMA/MOOSE guidelines. Dichotomous variables were pooled as odds ratios [OR]. Continuous variables were pooled as weighted mean differences [WMD]. Quality assessment was performed using the Newcastle-Ottawa score [NOS]. RESULTS: A total of 20 studies [five paediatric and 15 adult] with 4550 UC patients [without DLI, n = 2370, 52.09%; with DLI, n = 2180, 47.91%] were eligible for inclusion. The median NOS was 8 [range 6-9]. There was no increased risk of anastomotic leak [AL] (OR 1.13, 95% confidence interval [CI]: 0.92, 1.39; p = 0.25), pouch excision [OR 1.01, 95% CI: 0.68, 1.50; p = 0.97], or overall major morbidity [OR 1.44, 95% CI, 0.91, 2.29; p = 0.12] for RPC without DLI, and this technique was associated with fewer anastomotic strictures [OR 0.45, 95% CI: 0.29, 0.68; p = 0.0002] and less bowel obstruction [OR 0.73, 95% CI: 0.57, 0.93; p = 0.01]. However, RPC without DLI increased the likelihood of pelvic sepsis [OR 1.68, 95% CI: 1.03, 2.75; p = 0.04] and emergency reoperation [OR 1.74, 95% CI: 1.22, 2.50; p = 0.002]. CONCLUSION: RPC without DLI is not associated with increased clinically overt AL or pouch excision rates. However, it is associated with increased risk of pelvic sepsis and emergency reoperation. RPC without DLI is feasible, but should only be performed judiciously in select UC patient cohorts in high-volume, specialist, tertiary centres.

Survival outcomes after synchronous para-aortic lymph node metastasis in colorectal cancer: A systematic review.

BACKGROUND: Synchronous para-aortic lymph node metastasis (PALNM) in colorectal cancer (CRC) is a relatively rare clinical entity. There is a lack of consensus on management of these patients, and the role of para-aortic lymph node dissection (PALND) remains controversial. This systematic review aims to describe the survival outcomes in colorectal cancer with synchronous PALNM when lymph node dissection is performed. METHODS: A systematic review of Pubmed, Embase and Web of Science databases for PALND in CRC was performed. Studies including patients with synchronous PALNM undergoing resection with curative intent, published from the year 2000 onwards, were included. RESULTS: Twelve retrospective studies were included. Four studies reported survival outcomes for rectal cancer, two for colon cancer and six as colorectal. Survival outcomes for 356 patients were included. Average 5-year overall survival (OS) was 22.4%, 33.9% and 37.7% in the rectal, colon and colorectal groups respectively. Three year OS in the groups was 53.6%, 46.2% and 65.7%. CONCLUSION: There remains a lack of quality data to confidently make recommendations regarding the management of synchronous PALNM in colon and rectal cancer cohorts. Retrospective data suggests a benefit in highly selective cohorts and therefore a case-by-case evaluation remains the standard of care.

Baseline Assessments of Psychomotor Aptitude Are Associated With the Future Operative Performance of Surgical Trainees: A Prospective Observational Cohort Study.

OBJECTIVE: This study sought to investigate the association between validated psychomotor ability tests and future in-theater and simulated operative performance. BACKGROUND: Assessments of visuospatial ability, perceptual ability, and manual dexterity correlate with simulated operative performance. Data showing the predictive value of such assessments in relation to future performance in the workplace is lacking. METHODS: Core surgical residents in Ireland recruited from 2016 to 2019 participated in assessments of baseline perceptual, visuospatial, and psychomotor ability; Pictorial Surface Orientation (PicSOr) testing, digital visuospatial ability testing, and manual dexterity testing. Operative performance was prospectively assessed using the in-theater Supervised Structured Assessment of Operative Performance (SSAOP) tool, and simulation-based Operative Surgical Skill (OSS) assessments performed over a 2-year core training period. SSAOP assessments were scored using a 15-point checklist and a global 5-point operative performance score. OSS assessments were scored using procedure-specific checklists. Univariate correlations and multiple linear regression analyses were used to explore the association between fundamental ability measures and operative performance. RESULTS: A total of 242 residents completed baseline psychomotor ability assessments. Aggregated fundamental ability scores were associated with performance in submitted workplace-based SSAOP assessments using the Total Checklist score ( P =0.002) and Overall Performance scores ( P =0.002), independent of operative experience, and undergraduate centile scores. Aggregated ability scores were also positively associated with simulation-based OSS assessment scores on multivariable analysis ( P =0.03). CONCLUSION: This study indicates that visuospatial, psychomotor, and perceptual ability testing scores are associated with the future operative performance of surgical residents.

Training and assessment using the LapSim laparoscopic simulator: a scoping review of validity evidence.

INTRODUCTION: The LapSim (Surgical Science, Sweden) laparoscopic simulator is a high-fidelity virtual reality simulator for use in endoscopic surgical training. This review critiques the current validity evidence for the LapSim laparoscopic simulator, specifically with respect to its potential use as a tool and method of training and assessment in surgery. METHODS: A scoping review of the MEDLINE (PubMed), EMBASE, Cochrane and Web of Science databases was conducted in accordance with PRISMA guidelines (2020)-scoping review extension. Articles were included if they presented validity evidence for the use of the LapSim in operative skill training or assessment, in accordance with Messick's validity framework. European Association of Endoscopic Surgeons (EAES) guidelines (2005) were used to provide recommendations for the use of the LapSim in operative performance training and assessments. RESULTS: Forty-nine articles were included. An EAES level 2 recommendation was provided with regard to the internal consistency reliability of automated performance metrics in assessing performance. An EAES recommendation of 2 was awarded with respect to the ability of the LapSim to discriminate based on case volume and overall laparoscopic experience (relationships with other variables). Performance assessment metrics on the LapSim correlate with improved performance in the operating room (EAES level of recommendation 1-consequential validity). CONCLUSION: The LapSim has accumulated substantial evidence supporting the validity of its use in surgical training and assessment. Future studies should explore the relationship between the achievement of performance benchmarks on the LapSim and subsequent patient outcomes, and interrogate the benefits of implementing virtual reality simulation training and assessment curricula in post-graduate surgical training programmes.

Optimal surgical management strategy for treatment of primary anorectal malignant melanoma-a systematic review and meta-analysis.

BACKGROUND: Primary mucosal anorectal malignant melanoma (AMM) is an invasive malignancy with poor survival. Management options have been variable, due to limited data and lack of randomised control trials available on the optimal surgical strategy. The aim of this review was to compare local excision versus radical resection. METHODS: A systematic search of articles in PubMed, Ovid, Scopus, and the Cochrane Library database was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The outcomes of interest were the impact that surgical strategy had on survival (primary) and recurrence rates (secondary) for the treatment of AMM, comparing sphincter sparing local excision (LE) versus extensive abdominoperineal resection (APR). RESULTS: Ten studies met the predefined criteria. Overall, there were 303 patients, with a median age of 58.2 years. Sixty-one percent (n = 187/303) had radical surgery (abdominoperineal resection) for the primary treatment of AMM. Overall, 5-year survival for the APR and LE was 23% and 32% respectively. Meta-analysis on the median OS noted no statistical difference between the two groups. However, local recurrence occurred in 20.82% and 47.04% in the APR and LE groups respectively. Meta-analysis observed a statistically significant reduction in recurrence when patients had an APR as primary treatment (OR 0.15, 95% CI = 0.08-0.28, p < 0.00001). CONCLUSION: Though local recurrence rates are more common with local excision of AMM, this does not confer an inferior OS when comparing LE versus APR. The decision to proceed with LE vs. APR should be made on a case-by-case basis.

Perspectives on simulation-based assessment of operative skill in surgical training.

INTRODUCTION: The perspectives of the wider surgical community toward simulation-based assessment (SBA) in training is a gap in the literature. This study aims to explore the factors associated with the acceptable use of SBA in surgical training, through the perceptions and experiences of a broad range of stakeholder representatives, building on findings from a review of the published literature. MATERIALS AND METHODS: Ten semi-structured interviews were conducted, using a sequential transformative qualitative methods approach, with representatives from identified key stakeholder groups; executive management, risk management, a practicing surgeon, an anaesthesiologist, a theatre-nursing representative, a representative from simulation industry, a patient, a medical student, a junior surgical trainee, and a senior surgical trainee. Interview transcripts underwent reflexive thematic analysis using an inductive and constructivist framework (NVIVO software, NVIVO 12, QSR International). RESULTS: Four themes emerged: the 'need' for SBA, the concept of a 'minimum standard', the 'optimum design' of an SBA framework, and 'fairness'. SBA is a potential solution to challenges in the current training environment. It emerged that it should not replace trainer judgement, but could ensure that trainees meet a minimum operative competency standard. SBA should be used to identify underperforming trainees early in training to provide targeted remediation. The application of SBA in high-stakes settings such as trainee selection, autonomy granting, and end-of training certification has perceived benefits over current assessment methods. CONCLUSIONS: This study builds on findings from prior research to explore factors regarding the acceptable use of simulation as an assessment method in surgical training, including perspectives from a broad range of stakeholder representatives. Findings can inform the development of simulation-based assessment curricula in surgical training.

Defining operative experience targets in surgical training: A systematic review.

BACKGROUND: The surgical learning curve is an observable and measurable phenomenon. Operative experience targets are well established as a proxy measure for operative competence in surgical training across jurisdictions. The aim of this study was to critique the available evidence regarding the relationship between operative experience in surgical training and trainee competence. METHODS: A systematic review of the PubMed, Embase, Web of Science, and Cochrane library databases was conducted in accordance with the Preferred Items for Systematic Reviews and Meta-Analyses guidelines. Articles were sought that defined the relationship between procedural volume in surgical training and trainee competence, proficiency, or mastery. The educational impact of included studies was evaluated using a modified Kirkpatrick model. RESULTS: Of 3,672 records identified on database searching, 30 papers were ultimately included. Fourteen studies defined operative experience thresholds using operative time as a surrogate measure of competence, whereas another 8 used trainer assessments of operative performance (Kirkpatrick level 3). A further 5 studies were able to determine the relationship between trainee case volumes and subsequent patient outcomes (Kirkpatrick level 4b). CONCLUSION: Many studies have recorded competent trainee performance in key index procedures after reaching experience threshold numbers in excess of currently mandated targets across jurisdictions. The evidence relating current operative experience targets to patient outcomes across a range of surgical subspecialties of surgical subspecialties is lacking. This review supports a move toward criterion-based referencing of operative performance targets in surgical training.
