Aim Surgery for ileal pouch–anal anastomosis ( IPAA ) has evolved over time, especially since the introduction of laparoscopy. The aim of this retrospective study was to report the impact of surgical evolution on outcome over a period of 25 years. Method All patients who had IPAA surgery for ulcerative colitis from 1990 to 2015 at the University Hospitals of Leuven were included. Patients were divided into three period arms (period A 1990–1999; period B 2000–2009; period C 2010–2015). The main outcome measure was anastomotic leakage. Results A total of 335 patients (58.8% male) with a median age of 39 years (interquartile range 32–49 years) at surgery were included. Median follow‐up was 5 years (interquartile range 2–10 years). Overall anastomotic leakage (grades A–C) was 14.9%. A significant decrease in leakage rate was observed over time (from 21.4% in period A to 12.1% in period B to 10.0% in period C; P = 0.04). The defunctioning ileostomy rate at the time of pouch construction decreased from 91.7% (period A) to 40.3% (period B) to 11.1% (period C) ( P < 0.001). We observed an increase in the use of laparoscopy (23.9% in period A vs 72.6% in period B, vs 84.4% in period C; P = 0.001) and a shift to a modified two‐stage procedure (4.1% in period A, vs 66.7% in period C; P < 0.0001). In a monocentric study with some of the data retrieved retrospectively it was not possible to account for the impact of preoperative nutritional status (weight loss, serum albumin level) or disease burden. Other outcome factors were not measured, for example sexual function and fecundity. Conclusion A higher rate of laparoscopic IPAA surgery, together with a shift towards modified two‐stage procedures, was associated with a lower leakage rate despite a reduction in the use of defunctioning ileostomy.
