The longest open reading frame of PKHD1 (polycystic kidney and hepatic disease 1), the autosomal recessive polycystic kidney disease (ARPKD) gene, encodes a single-pass, integral membrane protein named polyductin or fibrocystin. A fusion protein comprising its intracellular C-terminus, FP2, was previously used to raise a polyclonal antiserum shown to detect polyductin in several human tissues, ...

INTRODUCTION There are several variations in the morphologic characteristics of the extrahepatic biliary system. A hepaticocystic duct is one of the rare variations. CASE PRESENTATION A 69-year-old Asian man underwent a cholecystectomy for cholelithiasis. His cystic duct was not detected during surgery. An intraoperative cholangiography revealed that his common hepatic ducts drained directly ...

The Alagille Syndrome (AGS) is a heritable disorder affecting the liver and other organs. Causative dominant mutations in human Jagged 1 have been identified in most AGS patients. Related organ defects occur in mice that carry jagged 1 and notch 2 mutations. Multiple jagged and notch genes are expressed in the developing zebrafish liver. Compound jagged and notch gene knockdowns alter zebrafish...

Several Helicobacter species have recently been isolated from the bile and hepatobiliary systems of murine species, and are well recognized as a pathogen of the hepatobiliary disorder. This study was planned to investigate whether Helicobacter species possess a causative potential for human hepatobiliary disease, especially for hepatobiliary carcinogenesis. Bile and hepatobiliary tissue samples...

Biliary obstruction often follows advanced cancers of the biliary system, such as pancreas cancer, which requires a resection of the involved portion of the portal vein. To improve the patient's state of obstructive jaundice, bile drainage should be performed before the operation. Temporaryocclusion of the portal vein is inevitable for a resection and reconstruction of the portal vein, and its ...

Background: Hepatobiliary ascariasis is commonly reported from highly endemic regions like India, Bangladesh, Latin America, parts of Middle East and Africa. In humans, the usual habitat of Ascaris lumbricoides is the small intestine. When the worm load is high, then the worms tend to migrate away from the usual site and invade the biliary system. Material & Methods: Patients attending general ...

Primary biliary cirrhosis (PBC) is histologically characterized by chronic nonsuppurative destructive cholangitis (CNSDC) associated with destruction of small bile ducts. The pathogenesis of PBC, predominance of female, or the reason why biliary duct is selectively involved, however, remains unknown. Infectious or non-infectious noxious insults such as xenobiotic chemicals may precipitate in th...

BACKGROUND AND OBJECTIVES Laparoscopic transcystic common bile duct exploration (LTCBDE) is a complex procedure requiring expertise in laparoscopic and choledochoscopic skills. The purpose of this study was to investigate the safety and feasibility of treating biliary calculi through laparoscopic transcystic exploration of the CBD via an ultrathin choledochoscope combined with dual-frequency la...

background: our knowledge regarding the epidemiology of pancreatobiliary cancers in iran is limited. this study presents the first population-based report on pancreatobiliary cancers performed in five provinces of iran. materials andmethods: data used in this study were retrieved from population-based cancer registries in five provinces of iran (gilan, mazandaran, golestan, ardabil and kerman) ...

postcholecystectomy clip migration is rare and can lead to complications such as clip-related biliary stones. most of such incidents have been reported as case reports. this study reviews a case of postcholecystectomy clip migration. it can occur at any time but typically occur at a median of 2 years after cholecystectomy. clinical presentations are similar to those with primary or secondary ch...
