Background & Aims:
Many patients with inflammatory bowel disease receive corticosteroids and 6-mercaptopurine/azathioprine during elective bowel surgery. We investigated the postoperative infection risk for patients undergoing elective bowel surgery who were receiving corticosteroids and/or 6-mercaptopurine/azathioprine before surgery compared with patients not receiving these medications.
Methods:
A retrospective cohort study was conducted on 159 patients with inflammatory bowel disease who underwent elective bowel surgery. There were 56 patients receiving corticosteroids alone, 52 patients receiving 6-mercaptopurine/azathioprine alone or with corticosteroids, and 51 patients receiving neither corticosteroids nor 6-mercaptopurine/azathioprine. Postoperative infectious complications to time of discharge were categorized into major and minor complications.
Results:
Patients receiving corticosteroids had an adjusted odds ratio for any and major infectious complications of 3.69 (95% confidence interval [CI], 1.24-10.97) and 5.54 (95% CI, 1.12-27.26), respectively. The adjusted odds ratio for patients receiving 6-mercaptopurine/azathioprine for any and major infectious complications was 1.68 (95% CI, 0.65-4.27) and 1.20 (95% CI, 0.37-3.94), respectively.
Conclusions:
Preoperative use of corticosteroids in patients with inflammatory bowel disease who are undergoing elective bowel surgery is associated with an increased risk of postoperative infectious complications. 6-Mercaptopurine/azathioprine alone and the addition of 6-mercaptopurine/azathioprine for patients receiving corticosteroids was not found to significantly increase the risk of postoperative infectious complications.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
