Transverse perineal support improves long-term outcomes in patients undergoing stapled transanal rectal resection for obstructed defecation syndrome: a multicenter observational case-control study.

To evaluate the safety and long-term efficacy of stapled transanal rectal resection (stapled transanal rectal resection) combined with the transverse perineal support (transverse perineal support) procedure in the surgical treatment of obstructed defecation syndrome (obstructed defecation syndrome) associated with internal rectal prolapse and excessive perineal descent (perineal descent).
