The most common complication of Crohn disease, occurring in 30-50% of patients, is small bowel obstruction. Typically, it is due to intestinal strictures from repeated bouts of inflammation and subsequent fibrosis. For a partial or complete obstruction refractory to nonsurgical management, surgical intervention is required. Surgical options include resection of the strictured bowel and strictureplasty. For long (> 12 cm) strictures or multiple strictures in close proximity, surgical resection with primary anastomosis is often required.
