Obstructive jaundice by vascular compression is rare. The causative arteries were identified as the right hepatic artery, gastroduodenal artery, cystic artery, proper hepatic artery, and an unspecified branch of the common hepatic artery. Also the venous system, such as enlarging collateral veins in cases of portal hypertension was a causative vessel. Herein, we describe a case of a proximal choledocholithiasis due to compression of the common bile duct by right hepatic artery originated from gastroduodenal artery. Final diagnosis and treatment were achieved through an operation.

Hepatic peribiliary cysts (HPCs) are characterized by cystic dilatations of the peribiliary glands located throughout the branches of the biliary systems. Specifically, they are mainly located along the hepatic hilum and major portal tracts. The natural history and prognosis of HPCs are uncertain. In fact, almost all HPCs have been discovered incidentally during radiological examination or autopsy, and they are considered to be clinically harmless. Recently, several cases of HPCs associated with obstructive jaundice or liver failure were reported in patients with pre-existing liver disease in several studies. However, until now there have been no reports of such a case in Korea. Herein, we report a case of HPCs that show a disease course with a poor prognosis. These HPCs developed in a 47-year-old man with progressive alcoholic liver cirrhosis.

We experienced one fatal case of biliary cast syndrome after cadaveric liver transplantation involving both intrahepatic ducts. A 58-year-old man underwent cadaveric liver transplantation because of hepatitis B virus related liver cirrhosis and concomitant hepatocellular carcinoma. Five weeks after the liver transplantation, postoperative course was complicated by development of acute cholangitis. Subsequent endoscopic retrograde cholangiography revealed diffuse intrahepatic bile duct strictures without filling defects. Percutaneous liver biopsy, which was done to exclude rejection, revealed biliary cast. Successful endoscopic removal was precluded due to its diffuse involvement. Because of the deterioration of patient's condition by refractory biliary obstruction and cholangitis, retransplantation from cadaveric donor was performed. Debridement of the biliary tree after graft removal yielded a near-complete cast of the intrahepatic ductal system. Biliary cast syndrome should be suspected when jaundice or cholangitis is associated with dilated ducts on abdominal imaging studies in cadaveric liver transplantation recipients. Initial therapeutic options include removal of biliary cast after endoscopic or percutaneous cholangiography. Although endoscopic retrieval of biliary cast by endoscopic retrograde cholangiopancreatography could be employed as a first-line management, other modalities such as endoscopic nasobiliary drainage, percutaneous transhepatic drainage, or retransplantation should be considered when complete removal is not feasible and the condition of the recipient deteriorates.

We report an extremely rare case of metastatic common bile duct cancer from pulmonary adenocarcinoma presenting as obstructive jaundice. The patient was a 76-year-old male, who presented with generalized weakness and right upper quadrant pain. Plain chest X-ray noted multiple small nodules in both lung fields. Abdominal computed tomography scan showed a stricture of the mid common bile duct along with ductal wall enhancement. Endoscopic retrograde cholangiography revealed a concentric, abrupt narrowing of the mid-common bile duct suggestive of primary bile duct cancer. However, pathology comfirmed metastatic common bile duct cancer arising from pulmonary adenocarcinoma with immunohistochemical study with thyroid transcriptional factor-1 (TTF-1).
