Nonvisualization of the gallbladder during the second trimester of pregnancy should prompt concern for biliary atresia. A normal-sized gallbladder with irregular and crenelated wall associated with a cyst of the extrahepatic tract should raise concern for cystic biliary atresia.

Several species of Helicobacter colonize the hepatobiliary tract of animals and cause hepatobiliary diseases. The aim of this study is to investigate Helicobacter found in the biliary tract diseases of humans. Thirty-two bile samples (15 from bile duct cancer, 6 from pancreatic head cancer, and 11 from intrahepatic duct stone) were obtained by percutaneous transhepatic biliary drainage. Polymer...

AIM The aim of the present study was to evaluate a single-center experience in hepatic arterial infusion (HAI) of patients with biliary tract carcinomas. PATIENTS AND METHODS A retrospective analysis of 60 patients treated between 1997 and 2011 was performed. RESULTS Most patients were treated with HAI of a combination of 5-fluorouracil, folinic acid and cisplatin. The response was not eval...

Surgery on the biliary tract has posed a challenge for the surgeon. The anatomic anomalies in this area demand careful identification of the relevant structures. Apart from anatomic variations, there are congenital anomalies of biliary tree that arise from normal morphological development; variations in the division of the extra hepatic biliary ducts are very frequent and understandable by the ...

We present the case of a 38-year-old woman diagnosed with metastatic adenocarcinoma of the biliary tract in the 18th week of pregnancy. Chemotherapy based on cisplatin and gemcitabine was administered, reaching disease stabilization until late-preterm delivery at 35 + 0 weeks of gestation. The infant was healthy and showed no malformations. Her head circumference was small, yet no neurological ...

H.j CHAKRAVARTI (School of Tropical Medicine, Calcutta) Streptomycin, when parenterally administered, is partially excreted and concentrated in the bile (Zintel ct ai, 1945), and in this way it can be effectively used in any infection of the biliary tract by streptomycin-sensitive organisms. In the transient jaundice of infective hepatitis, a viral infection, streptomycin is of no use. But in t...

The production of bile is an essential function of the liver. It contains cholesterol, bile acids, pigments and electrolytes, and their concentration is modified when the bile transits through the biliary tract. The bile is produced by the hepatocytes and is secreted into the bile canaliculi. These canaliculi are delineated by the apical membrane of the hepatocytes and are connected to the netw...

The presence of a stone or stones within the common bile duct (CBD) is known as choledocholithiasis. Choledocholithiasis is reported in 3%-22% of patients undergoing cholecystectomies [1]. A confirmatory diagnosis of choledocholithiasis is made using advanced imaging, including magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP). Treatment varie...
