Duodenal Crohn’s disease

Duodenal Crohn’s disease

The duodenum is an uncommon site for CD and involvement is more commonly the result of inflammation in another part of the bowel as a bystander e ff ect (secondary). This can often be managed by resection of the source of the fistula with direct duodenal repair if the defect is small or closure using an omental patch or duodenojejunostomy if the defect is sizeable. Duodenal strictures may be amenable to endoscopic balloon dilatation; however, strictureplasty , bypass gastrojejunostomy or gastroduodenostomy may be required.
