2024年9月26日 · The biliary tree is a branching system of ducts that delivers bile produced in the hepatic parenchyma toward the gallbladder and duodenum. By convention the biliary tree is divided into intra- and extra-hepatic bile ducts 1.

Through this work, we tried to study the anatomy extra-hepatic biliary tree of the population of the Center-east of Tunisia and to determine the frequencies of biliary anatomic variations in post-operative cholangiographies.

2022年12月15日 · Derived from the ventral foregut endoderm, the biliary tract forms during the fourth week of embryonic development. Between weeks 4 and 8, the extrahepatic bile ducts develop via the lengthening of the caudal portion of the hepatic diverticulum.

2016年9月9日 · MRI findings include marked intra- and extrahepatic ductal dilatation, with multiple focal strictures, and decreased arborization of the biliary tree. Multiple biliary stones of varying sizes, measuring up to several centimeters, are seen as filling defects with low signal on T2-weighted images and low-to-intermediate signal on T1-weighted images.

The anatomy facing a surgeon during cholecystectomy involves complex relationships between the hepatic artery, extrahepatic biliary tree, and gallbladder. A sound knowledge of the normal anatomy of the extrahepatic biliary tract is thus essential in the prevention of operative injury to it.

The extrahepatic biliary tree includes the common hepatic duct, which joins with the cystic duct from the gallbladder to form the common bile duct. The common bile duct then continues to the duodenum, where it delivers bile to aid in digestion.

2021年8月12日 · Results: Out of a total population of 293 patients, we identified 158 patients (53.9%) with anatomic variants of the extrahepatic bile ducts. The common bile duct was modally implanted in the...

The biliary tree is the ductal system that conducts bile from the liver to the second part of the duodenum. Anatomical textbooks and literature typically divide the biliary tree into intrahepatic and extrahepatic parts [1,2].

Aim: To study the modal anatomy (the most frequent) and the anatomical variants of the extrahepatic bile ducts through the interpretation of postoperative cholangiograms and to examine their implication on the surgical practice.

The morphometry and morphology of the components of extrahepatic biliary tree show extensive variations. A beforehand recognition of these variations is very crucial to prevent unintended complications while performing surgeries in this region.
