Parapapillary choledochoduodenal fistula: an analysis of 83 consecutive patients diagnosed at ERCP.

Eighty-three patients with parapapillary choledochoduodenal fistula diagnosed at endoscopic retrograde cholangiopancreatography over a 10-year period were reviewed. Three cases were associated with carcinoma of the papilla; the remaining 80 (37 female, 43 male) had gallstones. Thirty-one patients had choledocholithiasis, 12 had gallbladder stones, and 14 had intrahepatic stones. Fifty-five patients (69%) had a history of jaundice, whereas 23 (29%) had never experienced jaundice.
