<p><strong>Background: </strong>Patients in rural areas have limited colonoscopy access, which is critical for colorectal cancer prevention. General surgeons perform most colonoscopies in rural areas. The Surgical Collaborative of Wisconsin's Rural Task Force identified colonoscopy as a high-priority initiative due to high volume and lack of access to quality measurement, which is necessary to assess and ultimately improve colonoscopy performance.</p><p><strong>Objective: </strong>Assess the capacity for colonoscopy quality measurement and improvement in rural Wisconsin hospitals.</p><p><strong>Design: </strong>From October 2019 to January 2020, the Surgical Collaborative of Wisconsin, Rural Wisconsin Health Cooperative, and Wisconsin Collaborative for Healthcare Quality collaborated to design and distribute a survey to 44 Rural Wisconsin Health Cooperative hospitals.

Most colonoscopy providers in rural hospitals were surgeons (66.3%), followed by family/internal medicine physicians (20.0%) and gastroenterologists (13.8%). The average hospital volume/week was 19.9 colonoscopies (SD = 13.4). Hospitals reported operating at ~75% capacity. Withdrawal time was the most tracked measure (44.0%), followed by adenoma detection (36.0%) and cecal intubation (28.0%) rates. Approximately one-third of hospitals (36.0%) used procedure-reporting software. Most hospitals (80.0%) did not have access to on-site pathology.

<p><strong>Background: </strong>Pelvic mucosal melanomas, including anorectal and urogenital melanomas, are rare and aggressive, with a median overall survival of up to 20 months. Pelvic mucosal melanomas behave differently from their cutaneous counterparts and present late with locoregional disease, making pelvic exenteration its only curative surgical option.</p><p><strong>Objective: </strong>This study aimed to evaluate the survival outcomes after pelvic exenteration in pelvic mucosal melanomas at Royal Prince Alfred Hospital.</p><p><strong>Design: </strong>Retrospective case series from a prospectively collected pelvic exenteration database from October 1994 to November 2023.</p><p><strong>Setting: </strong>Royal Prince Alfred Hospital (quaternary institution), Camperdown, New South Wales, Australia.</p><p><strong>Patients: </strong>Seven patients undergoing pelvic exenteration for pelvic mucosal melanoma.</p><p><strong>Main outcome measures: </strong>Overall survival, disease-free survival, and complication rates.</p><p><strong>Results: </strong>Of the 7 patients, most were women (n = 5; 71.4%) and had a median age of 65 years (range, 36-79). Five patients (71.4%) underwent pelvic exenteration for primary pelvic mucosal melanoma, 3 of which were anorectal and 2 vaginal melanomas. Two patients (28.6%) had recurrent anorectal melanoma and received neoadjuvant radiotherapy after an initial wide local excision. Three patients (42.9%) required total pelvic exenteration, whereas 2 required a central pelvic exenteration (28.6%). The remaining procedures included central and lateral pelvic exenteration and anterior, central, and lateral pelvic exenteration. The median length of hospital stay was 19.7 days. Five patients had postoperative complications with 1 major complication (Clavien-Dindo grade IIIa). At the completion of the study, there were 4 mortalities. Mean survival was 23.6 months (range, 2-100) with a recurrence rate of 83%. The median time to recurrence was 3 months, despite 6 patients (85.7%) having R0 resections.
