Background: Ileal pouch anal anastomosis (IPAA) is associated with a high 30-day hospital readmission rate. Risk factors and etiology of readmission remain poorly defined. We sought to determine the 30-day hospital readmission rate following IPAA at a high-volume center and identify any modifiable perioperative factors. Methods: A retrospective review of all patients undergoing two- or three-stage IPAA for chronic ulcerative colitis at our institution between 2002 and 2013 was performed. Analysis was performed on rate of readmission, readmission diagnosis, intervention performed upon readmission, and risk factors for readmission. Results: Thirty-day primary and secondary readmission rates after IPAA were 20.3% (n = 185) and 2.1% (n = 19), respectively. The leading etiologies for readmission included partial small bowel obstruction/ileus (n = 52, 21.9%), pelvic sepsis (n = 43, 18.1%), dehydration (n = 42, 17.7%), and venous thromboembolism (n = 31, 13.1%). While the majority of readmissions were managed medically (n = 119, 65.4%), 19.2% (n = 35) required radiologic intervention and 15.3% (n = 28) required a return to the operating room. On univariate analysis, younger age (p = 0.03) and female sex (p = 0.04) had a significantly increased risk of readmission. On multivariable analysis, BMI ≥ 30 (OR 0.51; 95% CI, 0.25–0.97, p = 0.04) was protective of readmission. Conclusions: Thirty-day hospital readmission following IPAA remains a common problem. Preventable etiologies of readmission include dehydration and venous thromboembolism (VTE). Future quality improvement efforts should focus on education regarding stoma output and extended VTE prophylaxis to decrease hospital readmission rates following IPAA.
