TYPE B CHOLEDOCHOCELE: A RARE PRESENTATION WITH A COMMON TREATMENT
Review of Literature and a case report

Abstract
Introduction: Biliary dilation is a rare disease involving intrahepatic and extrahepatic biliary tract abnormalities. Choledochocele or type III choledochal cyst (CC) is a lesion present in less than 2% of all reported cases and is defined as a cystic dilation of the distal common bile duct protruding into the duodenal lumen.
Objective: To report on the endoscopic treatment of type III common bile duct cyst, as well as a review of the literature on the subject.
Case presentation: A 61-year-old female patient complained of severe abdominal pain for one month, with no associated cholestatic signs. She underwent abdominal ultrasonography that showed cholelithiasis. First diagnostic suspicion was cholecystitis, so she underwent emergency open cholecystectomy. The patient presented a torpid post-surgical evolution with jaundice, where control ultrasound showed extrahepatic bile duct dilation. MRI cholangiography revealed a fusiform dilation of the proximal portion of the hepatocholedochal, compatible with a choledochal cyst.
Conclusion: Our case presented with relatively rare manifestations and involved one of the undiscussed categories of the Todani classification system; thus, highly relevant. Endoscopic sphincterotomy is a feasible and effective treatment for choledochocele including large and protruding ones.
