title: Immunosuppressive therapy does not increase operative morbidity in patients with Crohn's disease.
abstract: OBJECTIVE
  The aim of this study was to examine the impact of immunosuppressive therapy on the morbidity of intestinal surgery in patients with Crohn's disease.
  
  
  BACKGROUND
  An increasing number of immunomodulating agents are being used in the treatment of Crohn's disease. The effect of these medications on surgical morbidity is controversial.
  
  
  METHODS
  We performed a retrospective review of our prospectively maintained database of patients with Crohn's disease who underwent intestinal surgery between June 1999 and May 2010. The effect of perioperative immunomodulation on postoperative outcomes, specifically anastomotic complications, was evaluated. Predictors of postoperative morbidity among demographic and surgical variables were identified. Length of hospitalization and rate of hospital readmission were compared between groups. Comparisons were made using Student t test and Fisher exact test.
  
  
  RESULTS
  One hundred ninety-six intestinal procedures were performed. One hundred twenty-seven (64.8%) of these were performed among patients who received perioperative immunomodulation. Forty-six (23.5%) procedures were in patients who received >1 immunomodulating medication perioperatively. Complications occurred in 45 (23.0%) cases. There were 20 (10.2%) anastomotic complications, including 8 (4.1%) intra-abdominal abscesses, 8 (4.1%) anastomotic leaks, and 4 (2%) enterocutaneous fistulas. Preoperative treatment with steroids (P=0.21), 6-MP (P=0.10), and anti-tumor necrosis factor biologics (P=1.0) was not associated with increased postoperative anastomotic complications. Combination immunosuppressive therapy also did not increase morbidity (P=0.39).
  
  
  CONCLUSIONS
  In our series, single agent and combination immunosuppressive therapy given around the time of intestinal surgery did not increase the incidence of surgical complications in patients with Crohn's disease.
