Two Cases of Mucinous Ductal Ectasia of Pancreas with Normal Duodenoscopic Findings / 대한소화기내시경학회지

Fairly specific and important duodenoscopic findings for diagnosing mucinous ductal ectasia (MDE) of pancreas include a prominant ampulla, patulous ampullary orifice and extrusion of mucin through the ampulla. However, we have experienced two cases of mucinous ductal ectasia without these pathognomonic appearance of ampulla. Initially, two cases were admitted for evaluation of pancreatic multicystic lesions, and MDE was incidentally found. Their pancreatographic findings showed normal main duct and cystic dilatation confined to the branch ducts. On gross findings of surgical specimens, a duct dilatation with gelatinous mucin was localized at the uncinate process of the pancreas. Microscopically, the ductal epithelia containing mucin were lined with well-differentiated tall columnar cells showing focal hyperplastic change. We report these unusual cases of MDE with review of the literatures.

Three Cases of Anomalous Drainage of Common Bile Duct into the Duodenal Bulb / 대한소화기내시경학회지

Classic anatomical descriptions state that the common bile duct enters to the medial border of the second part of duodenum. Isolated case reports of the common bile duct in other sites, including the fourth part of duodenum, the pyloric canal, stomach, and the duodenal bulb, have appeared in the literature. We report three cases of anomalous drainage of the common bile duct into duodenal bulb, which caused recurrent cholangitis and peptic ulcer. All patients required choledochoenteric anastomosis to relieve their syrnptoms.
