Aim The aim was to investigate the overall postoperative complication rate within 90 days following ileal pouch–anal anastomosis (IPAA), with or without a diverting stoma, together with complications 30 days after stoma closure and overall pouch failure rate. Method This was a retrospective chart review including IPAA patients with or without a diverting loop‐ileostomy for ulcerative colitis (1 January 1983 to 31 December 2015). Demographic data and postoperative complications were retrieved and recorded. Results A total of 434 patients were included. A diverting loop‐ileostomy was performed in 348 patients (80%). Baseline data were similar in the two groups except for body mass index (BMI) and the ratio of women, which were significantly higher in the group without a protective ileostomy. Overall 90‐day complication rate after IPAA [Clavien–Dindo (CD) > 2] was similar in the two groups. Clinical anastomotic leaks (CD > 2) were higher in patients without a diverting stoma (9.3% vs 1.7%) ( P = 0.002). The odds ratio for leakage after adjustments (age, gender, immune‐modulating medicine and BMI) was 5.0 for omitting a diverting stoma ( P = 0.004). Complications (CD > 2) after loop‐ileostomy closure were seen in 61 cases (14.1%). Omitting a diverting stoma at IPAA demonstrated a non‐significant odds ratio of 1.04 (0.46, 2.38) ( P = 0.924) for pouch failure after adjustments (age, gender, immune‐modulating medicine, BMI, time from pouch formation and clinical leakage). Conclusion The overall postoperative surgical and medical complication rate within 90 days after IPAA was similar in the group with and without diverting stoma. Postoperative complication rate after reversal was 14%. Omitting a diverting stoma at IPAA demonstrated an increased risk of leaks but no significant risk of long‐term pouch failure.
