Theoritically, the advantge of TAMIS surgery over traditional trans-abdominal IPAA surgery incudes shorter operation time due to simulatous surgery transanlly and transabdominally, reduced operative difficulty in narrow male pelvis, less retained rectal cuff and less dog-ear formation. However, its adgange has not been proven in prospecitve randomized trials. The aim of current study is to compare the short and long-term postoperative outcome of transanal versus transabdominal minimally invasive proctectomy with ileal pouch-annal anastomosis in patients with ulcerative colitis.
