Infliximab in ulcerative colitis is associated with an increased risk of postoperative complications after restorative proctocolectomy

Abstract

Purpose: Little data exist regarding infliximab use in surgical decision making and postoperative complications in ulcerative colitis. Our goals were to determine the rate of postoperative complications in infliximab-treated ulcerative colitis patients undergoing restorative proctocolectomy and to determine whether three-stage procedures are more often necessary.

Methods: We studied a group of infliximab-treated patients and matched control subjects who underwent two-stage restorative proctocolectomy between 2000 and 2006. Postoperative complications were compared. In addition, the rate of three-stage procedures was compared between all infliximab- and noninfliximab-treated patients.

Results: A total of 523 restorative proctocolectomies were performed. In the infliximab group, there were 46 two-stage and 39 three-stage procedures. Covariate-adjusted odds of early complication for the infliximab group was 3.54 times that of controls (P = 0.004; 95 percent confidence interval (CI), 1.51-8.31). The odds of sepsis were 13.8 times greater (P = 0.011; 95 percent CI, 1.82-105) and the odds of late complication were 2.19 times greater (P = 0.08; 95 percent CI, 0.91-5.28) for infliximab. The odds of requirement for three-stage procedures was 2.07 times greater in the infliximab group (P = 0.011; 95 percent CI, 1.18-3.63).

Conclusions: Infliximab increases the risk of postoperative complications after restorative proctocolectomy and has altered the surgical approach to ulcerative colitis. Potential benefits of infliximab should be balanced against these risks.
