Transanal minimally invasive proctectomy for ulcerative colitis is beneficial in terms of short-term outcomes and defecation function.

Objective: Despite being reported safety, the advantages of transanal minimally invasive proctocolectomy (TAMIP) are controversial, and comparative studies on postoperative defecation function between ileal pouch-anal anastomosis (IPAA) using laparoscopic transanal manipulation (TAMIP-IPAA) and without this technique (traditional IPAA) are lacking. This study analyzed TAMIP's impact on short-term and postoperative defecation function in patients with ulcerative colitis (UC) to evaluate its safety and feasibility.

Methods: Inclusion criteria comprised patients with UC undergoing minimally invasive proctocolectomy at our hospital from May 2014 to May 2023.
