Choledochocele and recurrent pancreatitis. Diagnosis and surgical management.

A case history has been presented that reports a rare type III choledochal cyst (choledochocele) and describes the association of a choledochocele and recurrent acute pancreatitis. The most reliable diagnostic technique, as used in our patient and supported by our literature review, is endoscopic retrograde cholangiopancreatography. This case further supports surgical correction employing transduodenal sphincteroplasty. This procedure is highly recommended for management of the intramural choledochocele (type IIIc), especially when associated with recurrent pancreatitis. Finally, patients who present with recurrent pancreatitis without the usual historical or diagnostic findings of biliary tract or alcoholic disease should have a choledochocele included in the differential diagnosis.
