    Abstract Background: Transanal total mesorectal excision is a novel surgical treatment for mid to low rectal cancers. Norwegian population data have raised concerns about local recurrence in patients treated with transanal total mesorectal excision.
    Objective: This study aimed to analyze local recurrence and disease-free survival in patients treated by transanal total mesorectal excision for rectal cancer at a high-volume tertiary center.
    Design: This retrospective study used a prospectively maintained institutional transanal total mesorectal excision database. Patient demographics, treatment, and outcomes data were analyzed. Local recurrence, disease-free survival, and overall survival were analyzed using Kaplan-Meier analysis.
    Settings: The study was conducted at a single academic institution in Vancouver, Canada.
    Patients: All patients treated by transanal total mesorectal excision for rectal adenocarcinoma between 2014 and 2022 were included.
    Main outcome measures: The primary outcome was local recurrence-free survival.
    Results: Between 2014 and 2022, 306 patients were treated by transanal total mesorectal excision at St. Paul's Hospital. Of these, 279 patients met the inclusion criteria. The mean age was 62 years (SD ± 12.3), and 66.7% of patients were men. Restorative resection was achieved in 97.5% of patients, with a conversion rate from laparoscopic to open surgery of 6.8%. The composite optimal pathological outcome was 93.9%. The median follow-up was 26 months (interquartile range, 12-47), and 82.8% of patients achieved reestablishment of GI continuity to date. The overall local recurrence rate was 4.7% (n = 13). The estimated 2-year local recurrence-free survival rate was 95.0% (95% CI, 92-98) and the estimated 5-year local recurrence-free survival rate was 94.5% (95% CI, 91-98).
    Limitations: Limitations include the retrospective nature of the study and the generalizability of a Canadian population.
    Conclusions: Recent European data have challenged the presumed oncologic safety of transanal total mesorectal excision. Although the learning curve for this procedure is challenging and poor outcomes are associated with low volume, this high-volume single-center study confirms acceptable oncologic outcomes consistent with the current standard.

    Sobrevida sin recidiva despus de tatme experiencia institucional canadiense: ANTECEDENTES:La excisión total del mesorecto por vía transanal es un tratamiento quirúrgico novedoso para los cánceres de recto medio a bajo. Estudios sobre la población noruega han generado preocupación debido a la recidiva local en pacientes tratados con excisión total del mesorecto por vía transanal.OBJETIVO:Nuestra finalidad fué de analizar la recidiva local y la sobrevida libre de enfermedad en pacientes tratados mediante la excisión total del mesorecto por vía transanal, debido a un cáncer de recto en un centro terciario de alto volúmen.DISEÑO:El presente estudio retrospectivo, utiliza una base de datos institucional sobre la excisión total del mesorecto por vía transanal mantenida prospectivamente. Se analizaron los datos demográficos, de tratamiento y los resultados de los pacientes sometidos a la técnica mencionada. La recidiva local, la sobrevida libre de enfermedad y la sobrevida global se analizaron mediante el modelo de Kaplan-Meier.AJUSTES:El estudio se llevó a cabo en una sola institución académica en Vancouver, Canadá.PARTICIPANTES:Se incluyeron todos los pacientes tratados mediante excisión total del mesorecto por vía transanal causado por adenocarcinomas de recto entre 2014 y 2022.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la sobrevida libre de recidiva local.RESULTADOS:Entre 2014 y 2022, 306 pacientes fueron tratados mediante la excisión total del mesorecto por vía transanal en el Hospital St. Paul. De estos, 279 pacientes cumplieron los criterios de inclusión. La edad media fue de 62 años (DE ± 12,3) y el 66,7% de los pacientes eran varones. La resección restauradora se logró en el 97,5% de los pacientes con una tasa de conversión de cirugía laparoscópica en laparotomía del 6,8%. El resultado patológico óptimo combinado fué del 93,9%. La mediana de seguimiento fue de 26 meses (rango intercuartil 12-47) y el 82,8% logró el restablecimiento de la continuidad gastrointestinal hasta la fecha. La tasa global de recidiva local fué del 4,7% (n = 13). La sobrevida libre de recidiva local estimada a los 2 años fué del 95,0% (IC del 95%: 92-98) y del 94,5% a los 5 años (IC del 95%: 91-98).LIMITACIONES:Las limitaciones incluyen la naturaleza retrospectiva del estudio y la generalización de una población canadiense.CONCLUSIONES:Datos europeos recientes han cuestionado la supuesta seguridad oncológica de la excisión total del mesorecto por vía transanal. Si bien la curva de aprendizaje de este procedimiento es muy desafiante y los malos resultados se asocian con un volumen bajo, el presente estudio, unicéntrico de gran volumen confirma los resultados oncológicos aceptables consistentes con el estándar actual.

    Abstract Background: Rural general surgeons perform many procedures outside the conventional scope of the specialty. Unique to British Columbia, the Rural Practice Subsidiary Agreement (RSA) formally defines rurality in the province. Our goal is to understand the scope of practice for BC's rural general surgeons and whether it has been affected over time by changing privileging guidelines.
    Methods: Medical Services Plan (MSP) data were collected from 2011 to 2021 for procedures billed by general surgeons in communities defined by the RSA as rural. We categorized codes from the MSP based on surgical specialty. For each community, we calculated the totals for these categories considering what other surgical specialties were present as well as changes over time.
    Results: From 2011 to 2021, 222 905 procedures were performed in 23 rural communities in BC. Colonoscopies were the most frequently performed procedure (
    Conclusion: General surgeons working in rural communities perform a variety of procedures based on resources, community need, and access to other specialists. Over the last decade, this appears to have been influenced by new privileging guidelines. Understanding the scope of rural general surgery can inform training opportunities and, as there is a migration away from rural surgeons performing as many unconventional procedures, can elucidate the implications on patients and communities.

    Abstract Background: We measured changes in self-reported health and symptoms attributable to rectal prolapse surgery using patient-reported outcome (PRO) measures.
    Methods: A prospectively recruited cohort of patients scheduled for rectal prolapse repair in Vancouver, Canada between 2013 and 2021 were surveyed before and 6-months after surgery using seven PROs: the EuroQol Five-Dimension Instrument (EQ-5D-5L), Generalized Anxiety Disorder Scale (GAD-7), Pain Intensity, Interference with Enjoyment of Life and General Activity (PEG), Patient Health Questionnaire (PHQ-9), Fecal Incontinence Severity Index (FISI), Gastrointestinal Quality of Life Index (GIQLI), and the Fecal Incontinence Quality of Life Scale (FIQL).
    Results: We included 46 participants who reported improvements in health status (EQ-5D-5L; p ​< ​0.01), pain interference (PEG; p ​< ​0.01), depressive symptoms (PHQ-9; p ​= ​0.01), fecal incontinence severity (FISI; p ​< ​0.01), gastrointestinal quality of life (GIQLI; p ​< ​0.01), and fecal incontinence quality of life (FIQL) related to lifestyle (p ​= ​0.02), coping and behaviour (p ​= ​0.02) and depression and self-perception (p ​= ​0.01).
    Conclusion: Surgical repair of rectal prolapse improved patients' quality of life with meaningful improvements in fecal incontinence severity and pain, and symptom interference with daily activities.

    Abstract Aim: Prehabilitation for colorectal cancer has focused on exercise-based interventions that are typically designed by clinicians; however, no research has yet been patient-oriented. The aim of this feasibility study was to test a web-based multimodal prehabilitation intervention (known as PREP prehab) consisting of four components (physical activity, diet, smoking cessation, psychological support) co-designed with five patient partners.
    Method: A longitudinal, two-armed (website without or with coaching support) feasibility study of 33 patients scheduled for colorectal surgery 2 weeks or more from consent (January-September 2021) in the province of British Columbia, Canada. Descriptive statistics analysed a health-related quality of life questionnaire (EQ5D-5L) at baseline (n = 25) and 3 months postsurgery (n = 21), and a follow-up patient satisfaction survey to determine the acceptability, practicality, demand for and potential efficacy in improving overall health.
    Results: Patients had a mean age of 52 years (SD 14 years), 52% were female and they had a mean body mass index of 25 kg m
    Conclusion: This web-based multimodal prehabilitation programme was acceptable, practical and well-received by all colorectal surgery patients who viewed the patient-oriented multimodal website. The feasibility of providing active health coaching support requires further investigation.

    Abstract Background: With an ever-evolving digital and virtual world hastened by the COVID-19 pandemic, prospective colon and rectal surgery fellowship applicants must rely on online sources of information, such as websites, rather than in-person visits to fellowship programs. This study analyzes and evaluates the content and accuracy of colon and rectal surgery fellowship program websites.
    Methods: The Fellowship and Residency Electronic and Interactive Database website provides a complete collection of colon and rectal surgery fellowship websites based in the USA. The accessibility of the websites was verified via Google search, and relevant content for the applicants was evaluated based on 50-point criteria.
    Results: Analysis of 60 fellowship program websites was conducted, out of which only a fifth (20%) were kept up to date. Twenty-seven (45%) websites fulfilled 50% of the 50-point criteria. The most and least included data points were program overview (69%) and residential/housing information (24%). Most websites contained basic information relevant to international applicants but lacked crucial information such as visa sponsorship (12%) and city information (23%).
    Conclusion: An informative and easily accessible website is essential for prospective applicants to choose the best program for their career goals and academic needs. This study highlighted multiple areas for potential improvement in the colon and rectal surgery program websites. Individual colon and rectal surgery programs may benefit and attract more candidates to their programs through a fully optimized website design and content.

    Abstract Background: Unplanned hospital readmissions are associated with adverse patient outcomes and substantial healthcare costs. It remains unknown whether physician financial incentives for enhanced discharge planning can reduce readmission risk.
    Methods: In 2012, policymakers in British Columbia, Canada, introduced a $75 fee-for-service physician payment to incentivize enhanced discharge planning (the 'G78717' fee code). We used population-based administrative health data to compare outcomes among G78717-exposed and G78717-unexposed patients. We identified all non-elective hospitalizations potentially eligible for the incentive over a five-year study interval. We examined the composite risk of unplanned readmission or death and total direct healthcare costs accrued within 30 days of discharge. Propensity score overlap weights and adjustment were used to account for differences between exposed and unexposed patients.
    Results: A total of 5262 of 24,787 G78717-exposed and 28,096 of 136,541 unexposed patients experienced subsequent unplanned readmission or death, suggesting exposure to the G78717 incentive did not reduce the risk of adverse outcomes after discharge (crude percent, 21.1% vs 20.6%; adjusted odds ratio, 0.97; 95%CI, 0.93-1.01; p=0.23). Mean direct healthcare costs within 30 days of discharge were $3082 and $2993, respectively (adjusted cost ratio, 1.00; 95%CI, 0.95-1.05; p=0.93).
    Conclusions: A physician financial incentive that encouraged enhanced hospital discharge planning did not reduced the risk of readmission or death, and did not significantly increase or decrease direct healthcare costs. Policymakers should consider the baseline prevalence and effectiveness of enhanced discharge planning, the magnitude and design of financial incentives, and whether auditing of incentivized activities is required when implementing similar incentives elsewhere.

    Abstract Background: The COVID-19 pandemic led to many new provincial public health measures to reallocate resources in response to an impending surge of cases. These necessary decisions had several downstream effects on general surgery training. We surveyed the actions taken by Canadian general surgery training programs in response to the COVID-19 pandemic.
    Method: A mixed-methods survey was sent to all general surgery program directors to assess various domains in surgical education and modifications made because of the pandemic. Responses were quantified as proportions or qualitative narratives describing those changes.
    Results: Most programs (13/15) recalled residents from planned rotations and redistributed them to rotations considered as core required services, including acute care surgery, trauma surgery and intensive care. Many programs also restructured their acute care surgery models to allow for a group of "reserve" residents to replace trainees who became infected with SARS-CoV-2. In terms of clinical experience, there was a reduction in both clinical and operative exposure among trainees. The reduction in clinical exposure disproportionately affected junior residents, whose involvement in COVID-19 cases was restricted. Formal educational sessions were maintained, but delivered virtually. Many programs instituted a program of increased frequency of communication with trainees.
    Conclusion: Many programs embraced using virtual platforms for teaching. The demonstrated utility of virtual teaching may lead to rethinking how training programs deliver didactic teaching and expand teaching opportunities. However, many programs also perceived a decrease in clinical and procedural exposure, primarily affecting junior residents. More information is needed to quantify the deficit in learning incurred as a result of the pandemic as well as its long-term effects on resident competency.

    Abstract Background: The preferred perineal repair method for full-thickness rectal prolapse is the Altemeier procedure, a perineal proctosigmoidectomy with handsewn anastomosis. A recently described variant of this procedure combines the resection and anastomosis into 1 step by means of linear and transverse stapling. There are few published data comparing the characteristics and outcomes of these 2 approaches.
    Methods: This retrospective review, performed at 2 Canadian academic hospitals, compares surgical and cost outcomes between the perineal stapled prolapse resection (PSPR) and the Altemeier procedure. All patients who underwent these procedures between 2015 and 2019 were included.
    Results: There were 25 patients in the PSPR group and 19 in the Altemeier group. Patients in the PSPR group were significantly older than those in the Altemeier group (81 [95% confidence interval (CI) 70-92] yr v. 74 [95% CI 63-85] yr;
    Conclusion: PSPR is a safe, efficient and effective approach to perineal proctosigmoidectomy. It is associated with surgical outcomes comparable to those of the Altemeier procedure, but with a significant reduction in operative time and cost.
