Does infliximab infusion impact results of operative treatment for Crohns perianal fistulas?
PURPOSE: Infliximab is an effective treatment for active intestinal Crohn’s disease; however, the efficacy of infliximab in perianal Crohn’s disease is controversial. This study was designed to compare patients with Crohn’s disease who underwent perianal fistula surgery with or without infliximab infusion. METHODS: A retrospective chart review of 226 consecutive patients with Crohn’s disease who underwent operative treatment with or without infliximab (3-6 infusions of 5 mg/kg) from March 1991 through December 2005 was completed. Patients were classified as completely healed, minimally symptomatic (seton placement with minimal drainage and/or infliximab dependence), and failure (persistent or recurrent symptomatic fistula, diverting procedure, or proctectomy). RESULTS: A total of 226 patients underwent operative treatment alone (n = 147) or in combination with infliximab infusion (n = 79). Age, gender, and preoperative history of intestinal and perianal Crohn’s disease were similar bet
