Introduction: Congenital choledochal cyst is a congenital dilatation of the biliary tract often associated with a long common bilio-pancreatic duct without obstruction.
Patients and method: We report the case of two women who presented a congenital choledochal cyst.
Results: For the first patient, the diagnosis was effected during a laparoscopic cholecystectomy for a gall bladder lithiasis. The second one presented repeted access of angiocholitis. Echography and abdominal tomodensitometry found the congenital choledochal cyst. Percutaneous opacification of the cyst found a long common biliopancreatic duct in the second patient. A complete resection of the cyst with a cholangiojejunal anastomosis was performed for both patients. The treatment was successfull for the first one and the second one was deceased three days after the operation.
Conclusion: This case report underlines the clinical polymorphysm, the morphologic anomaly and the treatment of congenital choledochal cyst which require total resection.
