REsults of LOw Anterior Resections With or Without Preventive Stoma in Nonemergency Department
Sponsor: ANO Scientific and Practical Club for the Development of Modern Medical Technologies
Summary
The purpose of this multicenter randomized non-inferiority trial is to evaluate the safety of low anterior resection for rectal cancer performed with versus without a diverting stoma in patients with a low predicted risk of colorectal anastomotic leakage. The primary objective is to determine whether the rate of anastomotic leakage within 30 days after surgery in the no-stoma group is non-inferior to that in the diverting stoma group. The secondary objectives include comparison between groups regarding: Stoma rate at 1 year after surgery; Quality of life at 30 days and 1 year (EORTC QLQ-C30, EORTC QLQ-CR29, and LARS score); Short-term postoperative outcomes, including postoperative day metrics, length of hospital stay, and complications graded according to the Clavien-Dindo classification; Reoperation rates within 30 days and 1 year. Participants will include adult patients with mid- or low-rectal adenocarcinoma who are scheduled for radical minimally invasive total mesorectal excision and have a predicted risk of anastomotic leakage \<10% according to the study risk model.

Interventions
Without a preventive stoma
At the conclusion of total mesorectal excision (TME), a diverting ileostomy or transverse colostomy will be created at the discretion of the operating surgeon. The pelvic peritoneum over the anastomotic site will be closed, and a pelvic drain will be placed (the type of drain will be determined by the operating surgeon).
With a preventive stoma
The operating surgeon will follow the standard practice adopted at the respective center and will create either a diverting ileostomy or transverse colostomy at their discretion. The pelvic peritoneum will not be closed. Placement of a percutaneous pelvic drain adjacent to the anastomotic site is mandatory.
