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 ...

An obstructed biliary system is usually drained by endoscopic retrograde cholangiopancreatography, and when this is unsuccessful, the standard alternative technique is percutaneous transhepatic biliary drainage. Surgical biliary bypass may also be required. In recent years, endosonography has transformed from a solely diagnostic procedure to one with therapeutic capabilities. Endosonography-gui...

Postoperative benign biliary stricture in the anastomotic site is one of the most common complications of biliary-enteric anastomosis, with a rate of 6.87% after 2-13 years of follow-up. If untreated, biliary strictures can induce other complications such as recurrent cholangitis, intrahepatic stones, pancreatitis and secondary biliary cirrhosis. We report our experience with extracorporeal sho...

Biliary sludge may be a precursor of gall stones in man. The aim of this study was to determine the incidence of biliary sludge in a prospective study of 36 patients admitted to the intensive care unit for longer than two days. The presence of biliary sludge was determined by ultrasonography. Biliary sludge developed in 17 patients (47%), after a mean of 5.5 days in the intensive care unit. Pat...

OBJECTIVES To summarize the pathotyping and clinical manifestations of biliary cast syndrome in patients after an orthotopic liver transplant. MATERIALS AND METHODS The clinical manifestations, auxiliary examination, therapeutic regimen, and clinical efficacy of 103 biliary cast syndrome patients who underwent an orthotopic liver transplant were retrospectively analyzed. Patients were divided...

PURPOSE To evaluate the association of biliary cyst formation with cholangitis, portoenterostomy, biochemical abnormalities, using multidetector computed tomography (MDCT) and pathologic findings of end-stage liver disease. MATERIALS AND METHODS We retrospectively reviewed the 42 MCDT studies, clinical history and laboratory findings of 36 children with biliary atresia. RESULTS Biliary cyst...

INTRODUCTION Acute pancreatitis is common clinical presentation. Gall stone disease and alcohol consumption are most common etiologies. Detection of biliary etiology is important in order to provide definite management in form of cholecystectomy to prevent further attacks. Sensitivity for abdominal ultrasound to detect cholelithiasis is decreased to 67-87% in presence of acute pancreatitis. Dif...

BACKGROUND Chronic inflammatory conditions of the biliary tree strongly predispose patients to biliary carcinoma. The aim of this study was to evaluate the role of interleukin-6 (IL-6) expression during biliary carcinogenesis in bilioenterostomized hamsters. MATERIALS AND METHODS Syrian hamsters were subjected to either a choledochoduodenostomy (CD, n=11) or a simple laparotomy (SL, n=10) and...

BACKGROUND Occult cystobiliary communication (CBC) presents with biliary leakage, if the cystobiliary opening cannot be detected and repaired at operation. We investigated the clinical signs associated with the risk of occult CBC in the preoperative period by studying patients who developed biliary leakage after hydatid liver surgery. METHODS We analyzed the records of 191 patients treated fo...

On the basis of their abilities to bind bile acids and/or cholesterol, the physiological role(s) of liver fatty acid-binding protein (L-FABP) and sterol carrier protein (SCP) 2/SCP-x (SCP-2/SCP-x) gene products in biliary bile acid and cholesterol formation was examined in gene-ablated male mice. L-FABP (LKO) or L-FABP/SCP-2/SCP-x [triple-knockout (TKO)] ablation markedly decreased hepatic bile...
