Anatomic Variations of Extrahepatic Bile Ducts and Evaluation of the Length of Ducts Composing the Cystohepatic Triangle

SUMMARY:It is of paramount importance for surgeons to have a thorough knowledge of the normal anatomy of the extrahepatic bile ducts and its variations due to the high frequency with which they perform in this anatomic site. The cystohepatic triangle, or Calot's Triangle, is bound by the cystic duct, common hepatic duct, and the hepatic border; therefore, its surface area depends on the conformation of these ducts and is closely linked to surgical procedures performed in this region. It has been reported that the length and the position of these ducts may be related to the formation of bile duct stones, Mirizzi's syndrome, and bile duct cancer. Thus, the present work aims to analyze the configuration of the extrahepatic biliary tree and its possible variations, as well as measure the components that make up the cystohepatic triangle. For this task 41 samples from fixated human cadavers were analyzed, with 25 consisting of anatomic parts (liver and biliary tree) and 16 in situ samples. The extrahepatic biliary trees were dissected in order to measure the length of the common hepatic and cystic ducts with a digital caliper, and all anatomic variations were registered. The length of the common hepatic duct varied between 4.18 mm and 50.64 mm, with an average of 21.76 ± 9.51 mm. The length of the cystic duct varied between 7.28 and 38.88 mm, with an average of 19.11 ± 6.77 mm. Anatomic variations were found in 3 samples (7.3%): in one of them the cystic duct connected to the left hepatic duct; in another, the cystic duct connected to the right hepatic duct; in the third, there was a triple confluence of hepatic ducts (two right ducts and one left duct). The results are a contribution to the clinical and surgical anatomy of this region.

“…There is some discrepancy in the reported frequency of this form of anatomical anomaly; some studies quote an incidence of about 1% (Benson and Page, 1976), whereas others claim it to be the commonest type of anomaly of the extrahepatic ducts, occurring in up to 30% of cases (Gibney et al, 1987;Moosman and Coller, 1951). In a detailed autopsy study, Moosman and Coller (1951) found an incidence of 16%, 77% being single and the remaining complex with multiple or branching patterns.…”

Anatomical variations of the extrahepatic biliary tree: Review of the world literature

2001

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. Equally important, however, is an understanding of congenital variation of biliary and vascular anatomy, as the literature abounds with reports of specific anatomical variations, and their operative implications. This article reviews the world literature on congenital variation of extrahepatic biliary anatomy.

“…The common bile duct was absent, and the right hepatic duct emptied directly into the cystic duct. 2 Other cases of communicating extrahepatic biliary ducts have included ducts connecting the right hepatic duct and cystic duct, the right hepatic duct and common hepatic duct, and the right hepatic duct and the neck of the gallbladder. Accessory ducts from the left lobe have been reported that eventually drained into the common hepatic duct.…”

Several variations in intrahepatic and extrahepatic accessory biliary ducts have been reported in the past. An accessory extrahepatic biliary duct connecting the lateral segment of the left lobe to the medial segment of the left lobe is described. A review of the literature reveals that this anomaly has rarely been reported in the past. Knowledge of such anomalies is critical in the prevention of iatrogenic injuries during surgery.
