Background And Aims: It is unclear whether infliximab treatment induces increased complication rates after surgery for ulcerative colitis. Aim was to compare complication rates after pouch surgery in refractory ulcerative colitis patients with versus without previous infliximab therapy.
Methods: We performed a retrospective study evaluating all patients who underwent an ileoanal J-pouch for refractory ulcerative colitis over a four-year period. Postoperative complications, infliximab use and time between last infliximab administration and restorative surgery were assessed. 1-stage procedures (proctocolectomy with pouch, with or without temporary diversion) and 2-stage procedures (emergency colectomy and subsequent completion proctectomy with pouch, with or without temporary diversion) were analyzed separately.
Results: Seventy-two patients were included; 33 underwent 1-stage procedure and 39 had 2-stage surgery. In the 1-stage group, 21 patients (64%) had previous infliximab therapy (median time between last infusion and surgery: 7.1 months (IQR 2.6-8.3)). Infliximab-treated patients had higher incidence of pelvic sepsis (5/21 vs. 0/12; risk difference 24%; 95% CI: 6 to 42, p=0.067) and non-infectious complications (8/21 vs. 1/12; risk difference 30%; 95% CI: 4 to 56, p=0.065). In the 2-stage group, 17 (44%) had previous infliximab therapy (median time between last infusion and surgery: 11.8 months (IQR 7.3-15.5)). Total, infectious, non-infectious complication rates and pelvic sepsis rates were similar for infliximab and non-infliximab patients in the 2-stage group.
Conclusions: This small study suggests that infliximab use prior to 1-stage restorative proctocolectomy in patients with UC is associated with increased incidence of pelvic sepsis. A 2-stage procedure in these patients should be considered.
