Abnormal biliopancreatic ducts are very uncommon in adults with the ex
ception of those associated with abnormalities of either the pancreati
c or the bile ducts. The case presented herein is unique in that a bil
iopancreatic connection occurred proximal to the papilla of Vater and
the patient was symptomatic because of the aberrant connection. The su
rgical therapy consisted of cholecystectomy and ligation of the aberra
nt duct, with complete relief of severe, debilitating symptoms. This i
nteresting clinical observation is discussed in the light of Opie's th
eory of biliary reflux into the pancreatic duct as a pathogenetic mech
anism for acute pancreatitis.
