First, the imaging modality used to evaluate the biliary system can influence the reported duct diameter. Extracorporeal ultrasonography measures the internal diameter of the duct (Fig. 33.2).2,3 Measurements of the CHD are typically obtained at the level of the hepatic artery in the porta hepat...
A swivel and tether system is employed to allow the rats to move freely. Waynforth and Flecknell (1992) described a surgical technique where a needle is passed through the flank skin into the abdomen. The bile duct is catheterized and ligated near the hilum of the liver and the catheter ...
Triaging BDI intraoperatively must only be aimed at draining the biliary system and placing a drain in the subhepatic region, then immediately referring the patient [9]. It is not justified to ligate the main biliary duct, as originally believed in old literature. Ligating the BD prolongs the...
the characterization of biliary strictures seen on imaging (multiphasic abdominal CT/MR with contrast enhancement, MRCP), alongside tumor markers (CEA, CA19-9), begins with endoscopic retrograde cholangiopancreatography, which utilizes fluoroscopy to create two dimensional images of the biliary system....
During meals, bile is released from the gallbladder through a tube called the common bile duct. This duct connects your gallbladder and liver to yourduodenum, the first part of your small intestine. Where is bile stored without a gallbladder?

(Perkin Elmer, Waltham, MA) and randomly arranged on the TMA. Liver micrograph images were captured using a high throughput Leica SCN400 Slide Scanner automated digital image system from Leica Microsystems (Buffalo Grove, IL). Whole slides were imaged at × 20 magnification to a resolution of ...
(PBS) and incubated with the secondary antibody for 1 hour at RT. Antibody binding was visualized by a liquid DAB Substrate Chromogen System (Dako, Glostrup, Denmark). The slides were rinsed in PBS and counterstained with hematoxylin. IHC images analysis was used software Image Pro Plus (...
From the liver a duct system carries bile to the common bile duct, which empties into the duodenum of the small intestine and which connects with the gallbladder, where it is concentrated and stored. The presence of fat in the duodenum stimulates the flow of bile out of the gallbladder ...
Injuries to the bile duct system during laparoscopic cholecystectomy are an unaltered cause for concern not necessarily related to the "learning curve" of the operating surgeon as suggested in the past [12]. In recent studies, it was demonstrated that in more than one-third of all bile duct ...
