are rare, and occur when there is bile stasis and a nidus for stone conglomeration [1,2]. Endoscopic examination of the bile duct has traditionally been difficult and is not routinely performed. We report the first case of management of recurrent bile duct stones using an ultrathin upper endoscope. A 54-year-old woman presented for endoscopic retrograde cholangiography (ERC) for removal of bili...

Background: To investigate the effects of bile duct stricture on the pharmacokinetics of the immunosuppressant tacrolimus, the pharmacokinetics of tacrolimus in rats with bile duct ligation were evaluated and the effects of the amount of intestinal bile on intestinal tacrolimus absorption were determined. Methods: In vivo pharmacokinetic studies and in vitro metabolic studies in rats with bile ...

Bile duct tumor thrombus (BDTT) of a hepatocellular carcinoma (HCC) is a rare entity which was found microscopically in 1 to 9.2% of the resected specimen.A 54-year-old male was found to have a 65-mm hepatocellular carcinoma in segment VI of the liver with a huge intrahepatic bile duct tumor thrombus. As the main trunk of the posterior segment branched from the left bile duct, the BDTT of the p...

BACKGROUND AND STUDY AIMS Endoscopic sphincterotomy (EST) is effective, but recurrent bile duct stones are a common late complication. Because there are still no effective therapies for preventing this complication, some patients have experienced bile duct stone recurrence many times. We describe herein a method of abdominal massage to treat patients with prior cholecystectomy who have experien...

Dilated bile duct is commonly seen in clinical practice and usually represents an obstructive lesion limiting the flow of bile. The evaluation of dilated bile duct is aimed to diagnose and treat the obstructive lesion. The clinical approach therefore requires (i) definition of normal limits of bile duct size (ii) predictive markers for obstruction & (iii) imaging modality for defining the level...

The purpose of this study was to investigate and discuss imaging methods and management strategies for congenital choledochal cyst with co-existing intrahepatic dilation and aberrant bile duct as well as other complicated biliary anomalies. In this study we reviewed and analyzed 72 patients with congenital choledochal cyst, ranging in age from 15 days to 12 years old and who were seen at our ho...

BACKGROUND Magnetic resonance cholangiography (MRC) is a new technique for non-invasive imaging of the biliary tract. AIM To assess the results of MRC in patients with suspected bile duct stones as compared with those obtained with reference imaging methods. PATIENTS/METHODS 70 patients (34 men and 36 women, mean (SD) age 71 (15.5) years; median 75) with suspected bile duct stones were incl...

Cholangitis requires bile duct obstruction and infection. Patients with cholangitis are often more affected than those with infections that reach the liver through the portal vein. We will attempt to study the influences of (i) route of entry and (ii) presence of bile duct obstruction on hepatic infection. C57BL/6 mice received injections of Escherichia coli or lipopolysaccharide into the obstr...

Introduction Adenosquamous carcinoma (ASC) of the bile duct is a rare diagnosis with poorly understood clinicopathological characteristics and disease progression, so identification of the features associated with ASC patient survival is warranted. Materials and methods A population cohort study was performed using prospectively extracted data from the Surveillance, Epidemiology and End Resul...

gallbladder and biliary tree is low compared with the many parenchymal hepatic conditions that occur in animals. Diseases of the extrahepatic biliary system are often confused with other intraabdominal disorders because their course and clinical signs are similar. Diseases that require surgery of the extrahepatic biliary system in dogs are primarily acquired and include extrahepatic biliary tra...
