DIAGNOSTIC IMAGING of the biliary tract is often required in liver transplant patients with suspected biliary com plications.u Direct cholangiography. either percutaneous transhepatic (PTC) or endoscopic retrograde. is the definitive radiological examination for the detection of biliary abnormalities.) Ultrasound (US) is noninvasive and accurate in detecting dilatation of the biliary tree. On t...

Previous experiments demonstrated that the biliary excretion of harmol sulfate (HS) was mediated by breast cancer resistance protein (Bcrp) and not by multidrug resistance-associated protein (Mrp)2 or P-glycoprotein in mice. However, recent reports suggested that species differences in hepatic canalicular transport mechanisms for a given substrate exist between mice and rats. In the present stu...

This is a retrospective study. The purpose of this study was to assess the diagnostic accuracy and utility of posttransplant magnetic resonance cholangiography (MRC) in detecting biliary complications and planning the treatment. From July 2006 to April 2010, 51 (19%) of these 268 adult living-donor liver transplantation (LDLT) recipients were referred to MRC due to biliary dilatation and abnorm...

Introduction Early diagnosis of biliary atresia is very important for better outcome of treatment. Ultrasonography is one of the diagnostic tools for early differentiation of biliary atresia from other causes of neonatal cholestasis. It has been reported that triangular cord sign (TACS) in sonography is a reliable sign for diagnosis of biliary atresia. The aim of this study was to re-assess the...

biliary liver flukes are common parasites in some regions of the world where consumption of raw fresh-water fish is a cultural practice. clonorchis sinensis and opisthorchis species are the major biliary liver flukes associated with human disease. some of these parasites are highly associated with cholangiocarcinoma. this report describes a clinically and epidemiologically unsuspected liver flu...

The goals of post-transplant management are to manage and treat postoperative complications, and develop a balanced long-term immunotherapy regimen that minimizes infection and side effects but controls rejection. While modern immunosuppressant regimes have reduced rates of graft loss due to rejection, they impart major risks for infection, growth failure, metabolic complications, and malignanc...

Background: Cholangiocarcinoma is an invasive biliary malignancy with poor prognosis. Diagnostic accuracy of conventional methods is low which is mainly due to the specific anatomy of the disease. The aim of this study was to evaluate the diagnostic value of biochemical profile and tumor marker of the bile in patients with malignant cholestasis compared to that of choledocholithiasis. ...

Selective biliary cannulation during endoscopic retrograde cholangiopancreatography (ERCP) is required to perform all therapeutic biliary procedures. Despite major advances in imaging, guidewires and sphincterotome catheter designs, the success rate for biliary cannulation by experienced endoscopists during ERCP is approximately 85% when standard cannulation techniques are applied. Precut sphin...

Calcium absorption, as measured by whole-body retention of isotopic (47)calcium, was investigated in 10 controls and 10 patients with primary biliary cirrhosis before and after medium-chain triglyceride therapy. Absorption of calcium was impaired in eight patients with primary biliary cirrhosis, three of whom had normal serum bilirubin. Mean absorption was significantly less in patients with pr...
