A 63-year male was admitted with abdominal pain, fever and jaundice. The contrast-enhanced computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiography showed a mass in the hepatic hilar region with dilation of the intrahepatic bile duct. The left branch of portal vein was also compressed by the mass. The patient was diagnosed as intrahepatic bile d...

BACKGROUNDS/AIMS In hepatocellular carcinoma (HCC), bile duct invasion occurs far more rarely than vascular invasion and is not well characterized. In addition, the pathologic finding of bile duct invasion is not considered an independent prognostic factor for HCC following surgery. In this study, we determined the characteristics of HCC with bile duct invasion, and assessed the clinical signif...

The bile duct system is a pathway of bile transportation from the liver to the intestine and plays a role of exocrine function of the liver. It consists of two different types of epithelial cells, hepatocytes and cholangiocytes. Anatomically as well as developmentally, the bile duct could be divided into intrahepatic bile duct (IHBD) and extrahepatic bile duct (EHBD; extrahepatic hepatic duct, ...

background disturbances in lipid metabolism which occur during hypothyroidism lead to the formation of gallstones. this study aims to evaluate the thyroid function pattern in patients with common bile duct (cbd) stones. methods this case-control study recruited 151 patients with preliminary diagnoses of cbd stone who underwent ercp (cases). the control group comprised healthy people who met the...

A 73-year-old woman was admitted because of obstructive jaundice. Computed tomography revealed a stricture in the lower bile duct with enhanced bile duct wall. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a tapering stenosis at the lower bile duct. Transpapillary histological biopsy using biopsy forceps through ERCP was performed; the diagnosis of signet ring cell carcinoma (S...

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 alo...

Intrahepatic stones are difficult to manage, especially when they are associated with bile duct stricture, cholangitis and destruction of liver parenchyma. Suggested modes of treatment include surgical bile duct exploration, endoscopic procedures, transhepatic cholangiolithotomy and liver resection. This paper reports 2 patients in whom liver resection was performed because of intrahepatic duct...

Mucinous cystic neoplasm (MCN) of the liver is a biliary counterpart of pancreatic MCN, usually occurring in the liver, but occasionally extending to the extrahepatic bile duct [1,2]. We present a case of MCN with extrahepatic bile duct extension diagnosed by peroral video cholangioscopy (POVCS). A 49-year-old woman was admitted with a week of vomiting without abdominal pain, and jaundice. Abdo...

BACKGROUND AND OBJECTIVES One-stage laparoscopic management for common bile duct stones in patients with gallbladder stones has gained wide acceptance. We developed a novel technique using a transcystic approach for common bile duct exploration as an alternative to the existing procedures. METHODS From April 2010 to June 2012, 9 consecutive patients diagnosed with cholelithiasis and common bi...

The malposition of a self-expandable metal stent (SEMS) placed fully inside the bile duct may be disastrous, and adjusting the position of a malpositioned stent can be difficult or impossible. Fully-covered SEMSs were designed mainly to treat benign biliary strictures and to be removable [1]. The removal process can however be difficult if the stent is placed fully inside the bile duct. Graspin...
