Integration of prolapsing technique and one-stitch method of ileostomy during laparoscopic low anterior resection for rectal cancer: a retrospective study.

Background: Prolapsing technique is a type of natural orifice specimen extraction surgery that can overcome the difficulty of precise transection of the distal rectum and subsequent anastomosis in a narrow pelvic space. Currently, protective ileostomy is widely utilized in low anterior resection for low rectal cancer, which may reduce the severe consequences caused by anastomotic leakage. The study aimed to combine the prolapsing technique with a one-stitch method of ileostomy and evaluate the surgical outcomes. Methods: A retrospective analysis was conducted on patients with low rectal cancer who underwent protective loop ileostomy in laparoscopic low anterior resection between January 2019 and December 2022. The patients were divided into prolapsing technique combined with the one-stitch method of ileostomy (PO) group and traditional method (TM) group, and the intraoperative details and early postoperative outcomes of the two groups were measured. Results: A total of 70 patients met the inclusion criteria, including 30 patients who underwent PO and 40 patients who underwent the traditional procedure. The PO group had a shorter total operative time than the TM group (197.8 ± 43.4 vs. 218.3 ± 40.6 min, Conclusion: This method is safe and feasible, which reduces the technical difficulty and achieves rapid postoperative recovery with few complications.
