Infections of the biliary tree include acute cholangitis or recurrent pyogenic cholangitis, characterized by obstruction, strictures, and central biliary dilatation. Inflammatory conditions include primary sclerosing cholangitis, which features strictures and fibrosis but can be difficult to differentiate from ...
Bile duct dilatation(indicates a possible stone in the distal bile ducts) If results from US scans are inconclusive, further imaging options are available. The gold standard investigation* for gallstones isMagnetic Resonance Cholangiopancreatography (MRCP), largely replacing ERCP for diagnostic purposes...
Because the biliary tree is lined with functionally heterogeneous epithelial cells, the site of injury produced by a particular toxin can vary from species to species. One of the better known toxicants is alpha-napthylisothiocyanate (ANIT). Only large bile ducts are injured in rats and mice, ...
Definition:: a rare,premalignantcondition characterized by extrahepatic and/or intrahepatic cystic dilatation of the biliary tree Epidemiology More common in individuals of Asian, in particular Japanese, descent Sex:♀>♂(3:1) Most commonly diagnosed during childhood(although25–50%are diagnosed in adul...
(2) periductal infiltrative type, of which tumor growth progresses along the bile duct longitudinally. This often results in upstream biliary tree dilatation and (3) intraductal polypoid type that proliferates focally within the lumen of the diseased bile duct [22]. Intrahepatic CCA are often of...

3. Biliary tree Biliary tract cancers exhibit unfavorable prognosis, often due to their frequent diagnosis at an advanced stage that is not amenable to surgical resection. 3.1. Cholecystitis Systemic anticancer treatment can cause uncommon but significant cholecystitis. Somatostatin analogs can cause acute...
Type IV (Fig. 5), only the intrahepatic bile duct dilata- tion, does not involve dilatation of the extrahepatic bili- ary tree which corresponds to Todani type V. As is shown in Table 1. Treatment for each type of CBD HUAXI classification type I, patients underwent cholecystectomy ...
Describe the physiology of the gallbladder and biliary tree and include the laboratory values associated with normal and abnormal function. Explain the sonographic evaluation of the gallbladder and biliary tree to include patient preparation, protocol, and demonstrate completing the examination procedure. ...
the liver is exteriorised out of the abdominal cavity. The entire extrahepatic biliary tree is excised together with the fibrous tissue occupying the space between the left and right branches of the portal vein at the level of the porta hepatis. A 45 cm Roux-en-Y loop is prepared and pa...
