Open surgery for inflammatory bowel disease (IBD) has been known to carry a high risk of incisional hernia, but the risk factors have not been well understood.
A review of 1,000 operations performed over nearly 40 years at a high-volume, nationally recognized center has identified five patient factors that can raise the risk of incisional hernia in these operations by 50% or more, according to a study published in the Annals of Surgery.

The study followed the patients for an average of 8 years after their operations, which were performed between January 1976 and December 2014 at Mount Sinai Medical Center in New York. The overall incidence of incisional hernia was 20%-21% for patients with ulcerative colitis and 20% for those with Crohn’s disease.
