Open vascular surgery remains crucial, demanding a steep learning curve. Exposure to these procedures has declined, resulting in a need for more standardization in acquiring open vascular surgery skills and potentially contributing to poorer outcomes. Simulation offers a solution, yet the evidence for structured programs in open vascular surgery is limited. This study aims to compare the efficacy of technical skill acquisition between a structured, progressive simulation-based training program and traditional experience-based training in open vascular surgery.\u0000Methods: A randomized, single-blinded, triple-arm educational clinical trial will be conducted. A control and intervention sequences of three groups with different exposure levels to the simulation program are proposed. Group 1: open abdominal aortic repair, Group 2: vascular anastomosis and open abdominal aortic repair, and Group 3: specific surgical skills, vascular anastomosis, and open abdominal aortic repair. 3D-printed models from AngioCT will be used for the open abdominal aortic repair simulation. Surgical residents of general, vascular, or cardiothoracic surgery programs will be included. Sample size calculation resulted in 45 participants, 15 per group. Simple blinding will involve external evaluators. Randomization will occur as simple randomization.\u0000Discussion: We expect that the structured and progressive simulation-based training program would enhance technical surgical skills. Based on the progression through different modules within the program, we aim to determine a significant difference in the acquisition of technical surgical skills. We hypothesize that 3D-printed patient-specific models can enhance participants' vascular surgery training and provide optimal simulated scenarios while prioritizing patient safety. We hope this initiative will impact the formation of future vascular surgeons, shape future training programs, and ensure comprehensive preparation for open vascular surgery.\u0000Trial registration: This study protocol was registered in clinicaltrials.gov with the NCT-ID: NCT06452901.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is increasingly common, affecting older people and those living with frailty. Currently, no guidance exists to define optimal care from onset of symptoms through to recovery. This paper presents the first consensus-built recommendations for best practice in the care of cSDH, co-designed to support each stage of the patient pathway. Methods\u0000Guideline development was led by a multidisciplinary Steering Committee with representation from diverse clinical groups, professional associations, patients, and carers. Literature searching to identify relevant evidence was guided by core clinical questions formulated through facilitated discussion with specially convened working groups. A modified Delphi exercise was undertaken to build consensus on draft statements for inclusion in the guideline using survey methodology and an in-person meeting. The proposed guideline was subsequently endorsed by the Society for British Neurological Surgeons, Neuroanaesthesia and Critical Care Society, Association of Anaesthetists, British Association of Neuroscience Nurses, British Geriatric Society, and Centre for Perioperative Care. Results\u0000We identified that high quality evidence was generally lacking in the literature, although randomised controlled trial (RCT) data were available to inform specific recommendations on aspects of surgical technique and use of corticosteroids. The final guideline represents the outcome of synthesising the available evidence as well as consensus-built expert opinion and patient involvement. The guideline comprises 67 recommendations across 8 major themes, covering: presentation and diagnosis, neurosurgical triage and shared decision-making, non-operative management, perioperative management (including of anticoagulation), timing of surgery, intraoperative care, postoperative care, rehabilitation and recovery. Conclusions\u0000We present the first multidisciplinary guideline for the care of patients with cSDH. The recommendations reflect a paradigm shift in the care of cSDH, recognising and formalising the need for multidisciplinary and collaborative clinical management and communication and decision-making with patients delivered effectively across secondary and tertiary care.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low Anterior Resection Syndrome (LARS) is one such consequence and describes a constellation of bowel symptoms after rectal cancer surgery which includes urgency, faecal incontinence, stool clustering and incomplete evacuation. LARS has a significant adverse impact on Quality-of-Life (QoL) and symptoms are present in up to 75% of patients in the first year after surgery. Despite this, little is known about the natural history and there is poor evidence to support current treatment options. Methods and Analysis\u0000The objectives of POLARiS are to explore the natural history of LARS and to evaluate the clinical and cost-effectiveness of trans-anal irrigation (TAI) or sacral neural modulation (SNM) compared to optimised conservative management (OCM) for people with major LARS. All patients who have had an anterior resection in the last 10 years who meet the eligibility criteria will be invited to participate in the cohort. Patients identified as having a major LARS score (LARS score ≥30) and who meet the eligibility criteria will be invited to take part in the randomised controlled trial (RCT). Cohort and RCT participants will be followed up for a 24-month period, and will complete a series of questionnaires measuring LARS symptoms and quality-of-life, as well as clinical review for those in the RCT. A process evaluation, qualitative sub-study and economic evaluation will also be conducted. The primary outcome measure of the POLARiS cohort and RCT is the LARS score at 24 months. Analyses of the RCT will be conducted on an intention-to-treat basis. Comparative effectiveness analyses for each endpoint will consist of two pairwise treatment comparisons: TAI vs OCM and SNM vs OCM.

Methods: The TriNetX federated database was used to identify patients with a diagnosis of cleft lip and/or palate undergoing primary cleft palate repair over a twenty-year period from 2003 until2023. Primary endpoints assessed include post operative hemorrhage resulting in blood transfusion and/or return to the operating room; Kaplan-Meier analysis was used for statistical analysis. Results: A total of 13,161 patients with cleft lip or palate over the last 20 years underwent operative intervention (palatoplasty). Of those patients, ninety-seven patients were found to have diagnosis of post-operative bleeding (confidence interval 1.196 +/-0.606). One hundred and seventy-five patients experienced post operative hemorrhage requiring transfusion of blood product (CI 1.491 +/-0.952). Seventy patients required return to the operating room for post-operative bleeding in the immediate post operative period. Conclusions: Historic reporting of post-operative bleeding suggests a moderate rate of post-operative hemorrhage rate following palatoplasty, occasionally necessitating transfusion and return to operating room following index palatoplasty.

Despite its clinical importance, epidemiological studies on ULVT are scarce, particularly in developing countries where the incidence may be heightened by factors such as traffic accidents and violence.\u0000Objective: To analyze the epidemiology of ULVT across Brazil, a developing country, evaluating incidence rates, demographic characteristics, mortality rates, days of hospitalization, and related healthcare costs.\u0000Methods: A cross-sectional, retrospective analysis using data from the Brazilian public health system (SUS) over a sixteen-year period (2008-2023). The automated data extraction utilized Python-based tools to gather information on vascular trauma procedures identified by ICD-10 codes. Statistical analyses were performed to assess variations in incidence, mortality, and treatment costs across Brazilian regions.\u0000Results: A total of 25,573 cases of ULVT were recorded, representing approximately 0.02% of the studied population. The majority of cases occurred in males (79.8%) with a mean age of 34.71 years, with a peak incidence in the 20-24 age group. The region in Brazil with the highest incidence of ULVT was the North (16.6 cases per 100,000 inhabitants) and the region with the lowest was the Southeast (10.7 cases per 100,000 inhabitants). The average hospital stay was 4.39 days and 92,8% of patients did not need to be admitted to an intensive care unit (ICU). Of the patients admitted to the ICU, the average length of stay was 4.52 days. Overall lethality (deaths per cases of ULVT) was 2.37%, with higher lethality observed in bilateral ULVT cases (3.81%). Conclusions: ULVT is more prevalent in Brazil than in developed countries, even when adjusted for population size. However, mortality rates and hospitalization durations do not appear to differ significantly from those in developed countries.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In resource-constrained environments, accurately estimating the costs of hospital services, such as robotic ventral hernia repair, is essential for achieving efficiency and transparency. Despite the existence of several studies reporting on the cost of robotic ventral hernia repair, there is a lack of systematic mapping of current knowledge on the methodological designs used in studies reporting on the costs and resource use.\u0000Methods: This study protocol outlines the methodology for a scoping review aimed at systematically mapping the existing literature on costing methodologies in robotic ventral hernia repair. The scoping review will follow the framework outlined by Arksey and O'Malley and adhere to the PRISMA-ScR guidelines. A systematic search will be conducted in Embase, Medline and Cochrane Library. Studies will be included if they involve patients undergoing robotic ventral hernia repair and report on cost/costing methodologies. The review will extract data on study characteristics, intervention specifics, and detailed costing methodologies. Two independent reviewers will conduct the data extraction, with discrepancies resolved through discussion or by a third reviewer.\u0000Discussion: The review will identify significant variations in costing methodologies, including differences in perspectives (hospital vs. societal), time horizons, and cost components. It aims to highlight gaps and inconsistencies in the current literature, providing a foundation for future research to standardize costing methodologies and improve the accuracy of economic evaluations in robotic surgery. By systematically mapping the existing literature, this scoping review will provide valuable insights into the current state of costing methodologies in robotic ventral hernia repair.

As the body of research grows, upholding high-quality standards becomes increasingly essential. Open science practices offer tools to ensure quality and transparency. However, the prevalence of these practices remains unclear. This study investigated the extent to which neurosurgical publications have implemented open science practices. Methods: Five open science practices (preprint, equator guidelines, published peer review comments, preregistration, and open accessibility to data and methods) were measured from five top-ranked neurosurgical journals (Neurosurgery, Journal of Neurosurgery, World Neurosurgery, Neurosurgical Review, and Acta Neurochirurgica), according to Google Scholar. One hundred fifty articles were randomly sampled from January 1, 2022, to December 31, 2023. Two reviewers analyzed these articles for their utilization of open science practices. A third reviewer settled disagreements. Results: One journal required (20%) and three journals (60%) recommended utilizing EQUATOR guidelines. Three journals (60%) allowed preprints, and all five journals (100%) recommended or required preregistration of clinical trials, but only two (40%) recommended preregistration for systematic reviews (Figure 1). All five journals (100%) recommended or required methods to be publicly available, but none (0%) published peer-review comments. Neurosurgical Review utilized the most open science practices, with a mean utilization of 1.4 open science practices per publication versus 0.9 across the other four journals (p &lt; 0.001). Moreover, Neurosurgical Review significantly utilized more open science practices versus Journal of Neurosurgery (p &lt; .05) and World Neurosurgery (p &lt; .05). Both randomized controlled trials (p &lt; .001) and systematic reviews (p &lt; .001) significantly utilized more open science practices compared to observational studies.
