Effect of high-dose steroids on anastomotic complications after proctocolectomy with ileal pouch–anal anastomosis

This review was designed to determine whether “high-dose” steroid therapy (⩾20 mg prednisone/day) increases the likelihood of anastomotic complications after restorative proctocolectomy with ileal pouch–anal anastomosis (IPAA). The hospital records of 100 patients undergoing proctocolectomy with IPAA were reviewed. Patient characteristics were analyzed to determine what factors were associated with higher rates of anastomosis-related complications. Seventy-one of our patients were given diverting ileostomies, whereas the remaining 29 underwent a single-stage procedure. Fifty-four percent of the patients in our review were taking steroids preoperatively, 39 of whom were on high-dose therapy. The overall anastomosis-related complication rate was 14%. There was no significant difference in complication rates with respect to age, steroid use, steroid dose, use of a diverting ileostomy, type of anastomosis, duration of disease, or presence of backwash ileitis. A trend toward higher leakage rates was found in patients undergoing single-stage procedures (10.3% vs. 2.8%, P = 0.14) as well as in patients undergoing single-stage procedures on high-dose steroids (22% vs. 5.0, P = 0.22). Nevertheless, neither of these trends was found to be statistically significant, which was likely influenced by the small sample size. Our data suggest that there may be an increase in anastomotic leakage rates in patients on high-dose steroids undergoing a single-stage proctocolectomy with IPAA. Nevertheless, our rate was not as high as the rates seen by other investigators and did not reach statistical significance. During preoperative counseling, patients on high-dose steroids should be informed of this uncertain but real risk of anastomotic leakage.
