Intraoperative Bowel Decompression Using an Endo GIA-to-Ultrasound Sleeve Anastomosis: A Novel Approach for Managing Unprepped Sigmoid Volvulus.

Acute large bowel obstruction from sigmoid volvulus in unprepped patients presents a significant intraoperative challenge due to the high risk of contamination when decompressing or resecting a distended, feces-filled colon. This paper describes a novel technique for safe and effective decompression of the colon using a linear GIA stapler to create an anastomosis between the descending colon and a sterile ultrasound (US) probe sleeve, enabling fecal evacuation without contamination of the operative field. A case report is presented, and the potential for this technique to be validated through future animal studies is discussed.
