Objective:The aim of this study was to identify the incidence and factors associated with the development of incisional hernia (IH) in patients with inflammatory bowel disease (IBD) undergoing open bowel resections.Background:Predisposing factors for IH have not been well studied in patients with IBD undergoing open bowel resection. The role of duration of the disease, nutritional factors, anti-inflammatory treatment, previous operative procedures, wound infection, and other complicating factors remains unclear.Methods:One thousand patients with ulcerative colitis and Crohn's disease were followed for a mean of 8 years after open bowel resection. The incidence of IH was recorded as well as correlating factors with the development of IH.Results:The overall incidence of IH in this series was 20% (21% for ulcerative colitis and 20% for Crohn's disease). Statistically significant risk factors for development of IH were wound infection (HR 3.66, P <0.001), hypoalbuminemia (HR 2.02, P = 0.002), history of previous bowel resection (HR 1.60, P = 0.003), creation of ileostomy at the time of procedure (HR 1.53, P = 0.01), history of smoking (HR 1.52, P = 0.013), body mass index at surgery (1.036, P = 0.009), age at surgery (HR 1.021, P <0.001), and age at the onset of disease (HR 1.018, P <0.001).Conclusions:Patients with IBD have a high incidence of incisional hernia after open bowel resection. Wound infection had the strongest correlation with the development of IH. The other factors were age at onset of IBD, age at surgery, body mass index, serum albumin, presence of ileostomy, previous surgical procedures, and history of smoking. Duration of disease, preoperative steroids, immunosuppressive therapy, and blood transfusion were not found to correlate with IH.
