    Abstract:
    OBJECTIVE: This study aims to compare surgical outcome of transanal ileal pouch-anal anastomosis (ta-IPAA) with transabdominal minimal invasive approach in ulcerative colitis (UC), using the comprehensive complication index (CCI). BACKGROUND: Recent evolutions in rectal cancer surgery led to transanal dissection of the rectum resulting in a better exposure of the distal rectum and presumed better outcome. The same approach was introduced for patients with UC, resulting in decreased invasiveness. METHODS: All patients, undergoing minimally invasive restorative proctocolectomy in 1, 2, or 3 stages between January 2011 and September 2016 in 3 referral centers were included. Only patients who underwent either multiport, single port, single port with 1 additional port, hand-assisted, or robotic (R) laparoscopy were included in the analysis. CCI, registered during 90 days after pouch construction, was compared between the transanal and the transabdominal approach. RESULTS: Ninety-seven patients (male: 52%) with ta-IPAA were compared to 119 (male: 53%) with transabdominal IPAA. Ninety-nine (46%) patients had a defunctioning ileostomy at time of pouch construction. A 2-step model showed that the odds for postoperative morbidity were 0.52 times lower in the ta-IPAA group (95% confidence interval [0.29; 0.92] P = 0.026). In patients with morbidity, mean CCI of the transanal approach was 2.23 points lower than the transabdominal approach (95% confidence interval: [-6.64-3.36] P = 0.13), which was not significant. CONCLUSIONS: Ta-IPAA for UC is a safe procedure, resulting in fewer patients with morbidity, but comparable CCI when morbidity is present. Overall, ta-IPAA led to lower CCI scores.
