Efficacy of transanal drainage tube placement in preventing anastomotic leakage after ileal pouch-anal anastomosis in patients with ulcerative colitis.

TDT placement was significantly associated with anastomotic leakage of IPAA in patients with UC undergoing surgery. Although two-stage surgery with ileostomy is usually preferred in UC surgery, our findings suggest that TDT placement might contribute to the improvement of postoperative outcomes after UC surgery.
