Choledochoduodenal fistula: a rare complication of peptic ulcer disease.

Choledochoduodenal fistula is a rare complication of peptic ulcer disease. Many cases are asymptomatic and incidentally diagnosed. Treatment is controversial and ranges from medical treatment of peptic ulcer disease alone, to vagotomy with antrectomy or gastroenterostomy. Common bile duct exploration and reconstruction are reserved for cases with biliary stricture.
