Introduction: For general surgeons practising in rural areas, multiple factors influence care beyond skills learned in residency. The British Columbia Privileging Dictionary (BCPD) defines core and non-core procedures that shape the scope of general surgeons. Moreover, the Royal College has adopted a Competence by Design (CBD) curriculum which employs entrustable professional activities (EPAs) that list surgical skill residents must be proficient in by graduation.

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.

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.

Objective: This systematic review and meta-analysis seeks to evaluate the impact of total neoadjuvant therapy (TNT) for rectal cancers on surgical complications and surgical pathology when compared with standard long-course chemoradiotherapy (LCRT).

Background: The oncological benefits of TNT are well published in previous meta-analyses, but there is little synthesized information on how it affects surgical outcomes. A recent study has suggested an increase in local recurrence and higher rates of breached total mesorectal excision (TME) plane in TNT patients.

Introduction: Hospital activity is often measured using diagnosis-related groups, or case mix groups, but this information does not represent important aspects of patients' health outcomes. This study reports on case mix-based changes in health status of elective (planned) surgery patients in Vancouver, Canada.

Data And Methods: We used a prospectively recruited cohort of consecutive patients scheduled for planned inpatient or outpatient surgery in six acute care hospitals in Vancouver.

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.
