A penetrating duodenal ulcer may occasionally erode into the common bile duct and form a choledochoduodenal fistula. Such a fistula occurring simultaneously with a pancreatic duodenal fistula is reported. The presenting features of these fistulas are those of the ulcer and confirmation of the fistula may be difficult, although use of endoscopic retrograde cholangiopancreatography has greatly facilitated their diagnosis. In this case both fistulas could be cannulated through the base of the ulcer. The majority of these fistulas heal spontaneously with intensive medical management. The remainder require surgery, and a conservative approach avoiding direct interference with the fistula should be adopted. Drainage procedures are rarely required and once closed the fistulas usually cause no further problem.
