We present a 42-year-old man with a 1-month history of painless jaundice, dark urine, clay-colored stools, and a 13.5-kg weight loss. Laboratory tests revealed elevated liver enzymes and CA19-9. Imaging showed dilation of both the intra- and extrahepatic bile ducts, narrowing of the bile duct at the junction of the common bile duct and common hepatic duct, and a hypoechoic mass involving the ne...

CONFLICT OF INTEREST NONE DECLARED Choledochal cyst is a congenital cystic dilation of a part of bile duct that occurs most commonly in the main part of common bile duct. Diagnosis of choledochal cyst is concluded upon disproportionate expansion of extrahepatic bile duct. Symptom trias are: abdominal pain, jaundice and abdominal mass represent clinical guideline signs of diagnosis. Furthermore,...

Bile duct cysts (BDC) are rare congenital anomalies of the biliary tree that are characterized by cystic dilatation of the extrahepatic and/or intrahepatic bile ducts. Presence of an anomalous bilio-pancreatic junction allowing pancreatic juice to reflux into the biliary tree is the most widely aetiopathogenic concept currently accepted. BDC are associated with biliary stasis and lithiasis, and...

A 49-year-old patient underwent cholecystectomy and Roux-en-Y hepaticojejunal anastomosis (●" Fig.1) for Mirizzi’s syndrome. Jaundice, pruritus, choluria, and acholia developed 4 months later. The total serum bilirubin was 21mg/dL, and magnetic resonance cholangiopancreatography (MRCP) demonstrated intrahepatic bile duct dilation and anastomotic stricture. Double-balloon enteroscopy was perform...

Although intrabiliary metastasis of carcinoma in the liver is unusual, intraductal and/or intraepithelial spread of cancer cells along intrahepatic bile ducts is now well recognized as hepatic metastasis. However, several clinical and laboratory findings, including images, lead us to differentially diagnose from primary intrahepatic cholangiocarcinoma. We report here on a case of colonic adenoc...

Intraductal papillary neoplasms of the bile duct (IPNB) leads to malignant transformation and mucin production. Herein, we presented two cases of mucin-producing IPNB with obstructive jaundice who underwent resection of the intrahepatic lesions and bypass hepaticojejunostomy. The first case was a 69 year-old male patient with 5-year follow up for gallstone disease. Imaging studies showed mucin-...

OBJECTIVE To describe the anatomical variation occurring in intrahepatic bile ducts (IHDs) in terms of their branching patterns, and to determine the frequency of each variation. MATERIALS AND METHODS The study group consisted of 300 consecutive donors for liver transplantation who underwent intraoperative cholangiography. Anatomical variation in IHDs was classified according to the branching...
