A novel technique for the construction of an end ileostomy to prevent stoma outlet obstruction after rectal resection and total colectomy: a single-center retrospective study.

Purpose: Stoma outlet obstruction (SOO) is an early postoperative complication of rectal cancer. We devised a novel surgical technique: end-ileostomy, to reduce SOO. Here, we describe the surgical technique used for constructing an end ileostomy and assess its impact on SOO.

Methods: The subjects of this retrospective study were 78 patients who underwent low anterior resection or total colectomy with a defunctioning ileostomy (DI) between 2018 and 2022. The surgical procedure for end ileostomy can be summarized as follows: First, the ileum was separated using a linear stapler, approximately 30 cm from the Bauhin valve; then the opposite sides of the mesentery of the oral and anal ilea were sutured; and finally, end ileostomy was performed using standard techniques. End and loop ileostomies were performed in 34 and 44 patients, respectively. We assessed the independent risk factors for SOO.

Results: SOO occurred in 12 patients (15.3%): 1 (2.9%) with an end ileostomy and 11 (25%) with a loop ileostomy. Multivariate analysis identified loop ileostomy as an independent risk factor for SOO (p = 0.037).

Conclusions: End ileostomy construction is a useful and safe technique for reducing the incidence of SOO in defunctioning ileostomies following rectal resection.
