A case of obstructive jaundice caused by a pancreatic pseudocyst successfully treated with pancreatic duct stenting

A man in his seventies presented to our hospital with obstructive jaundice. Contrast-enhanced abdominal computed tomography revealed a unilocular cystic lesion, measuring 53 × 47 mm in the pancreatic head, accompanied by distal bile duct stricture and upstream biliary dilatation. Endoscopic retrograde cholangiopancreatography revealed a smooth stricture of the distal bile duct, suggesting extrinsic compression, and pancreatography demonstrated communication between the main pancreatic duct and the cystic lesion. Thus, based on these findings, biliary and pancreatic duct stents were placed. The biliary stent was subsequently removed after 3 months following improvement of biliary obstruction associated with shrinkage of the pancreatic pseudocyst, without recurrence of jaundice. Overall, this case suggests that pancreatic duct stenting may be an effective treatment option for biliary obstruction caused by pancreatic pseudocysts with pancreatic duct communication.
