Abstract

<p>Objective: To clarify the short-term outcome of combined resection of adjacent organs and pelvic exenteration (PE) for locally advanced primary rectal cancer.</p><p>Methods: In our retrospective cohort study, we enrolled patients who underwent robotic surgery for rectal cancer with combined resection of adjacent organs between 2017 and 2023, and evaluated the short outcome.</p><p>Results: Of a total of 34 eligible patients, 26 patients (76.5%) were male, low rectal cancer was observed in 20 patients (58.8%), and 25 patients (73.5%) were cStage III. Sixteen patients underwent abdominoperineal resection, 8 underwent low anterior resection, and 5 underwent PE. Operating time was 334 (min) in cases undergoing combined resection except PE, and 617 (min) in PE. Total blood loss was 40/367 (mL), and postoperative hospital stay was 7/14 (days), respectively. The frequency of complications (Clavien-Dindo Grade II or higher) was 20% in total. The radial margin was positive in 7% except for PE cases, and 0% within PE cases.</p><p>Conclusion: The short-term outcomes of combined resection of adjacent organs and pelvic exenteration (PE) for rectal cancer were acceptable.</p>
