title: Spontaneous choledochoduodenal fistula secondary to long-standing ulcer disease.
abstract: There are several varieties of bilioenteric fistulae. They are usually incidental findings, but once detected, various modalities can then be employed to further delineate the fistula. The fistulae usually arise as a complication of chronic duodenal ulcer disease, cholelithiasis or previous instrumentation to the biliary system. The presence of a fistula per se does not immediately equate to necessity for surgery. The treatment is dependent on its aetiology.
