Popis: Purpose We report outcomes and evaluate patient factors and the impact of surgical evolution on outcomes in consecutive ulcerative colitis patients who had restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) at an Australian institution over 26 years. Methods Data including clinical characteristics, preoperative medical therapy, and surgical outcomes were collected. We divided eligible patients into 3 period arms (period 1, 1990 to 1999; period 2, 2000 to 2009; period 3, 2010 to 2016). Outcomes of interest were IPAA leak and pouch failure. Results A total of 212 patients were included. Median follow-up was 50 (interquartile range, 17 to 120) months. Rates of early and late complications were 34.9% and 52.0%, respectively. Early complications included wound infection (9.4%), pelvic sepsis (8.0%), and small bowel obstruction (6.6%) while late complications included small bowel obstruction (18.9%), anal stenosis (16.8%), and pouch fistula (13.3%). Overall, IPAA leak rate was 6.1% and pouch failure rate was 4.8%. Eighty-three patients (42.3%) experienced pouchitis. Over time, we observed an increase in patient exposure to thiopurine (P = 0.0025), cyclosporin (P = 0.0002), and anti-tumor necrosis factor (P < 0.00001) coupled with a shift to laparoscopic technique (P < 0.00001), stapled IPAA (P < 0.00001), J pouch configuration (P < 0.00001), a modified 2-stage procedure (P = 0.00012), and a decline in defunctioning ileostomy rate at time of IPAA (P = 0.00002). Apart from pouchitis, there was no significant difference in surgical and chronic inflammatory pouch outcomes with time. Conclusion Despite greater patient exposure to immunomodulatory and biologic therapy before surgery coupled with a significant change in surgical techniques, surgical and chronic inflammatory pouch outcome rates have remained stable.
