Surgical anatomy of hepatoduodenal ligament and hepatic hilus (original) (raw)

Abstract.

The anatomical situation and variations of structures in the hepatoduodenal ligament and hepatic hilus are a legacy of their embryological development. The vascular, biliary, and lymphatic structures contribute to the functioning of blood and bile flow as well as lymph drainage of the liver. Connective tissue, fatty tissue, and the peritoneal sheet are enveloping underlying structures. Their position, shape, and relation to neighboring structures influence the situation during operative procedures. The cystic artery origin is variable, as is the number; and its recognition is important for safe cholecystectomy. Venous drainage of the gallbladder goes into the portal system of adjacent segments 4 and 5 and influences the spread of gallbladder pathology. There are some surgically important variations in the course and distribution of bile ducts and arteries in the hepatoduodenal ligament. The biliary anatomical variations significantly influence the incidence of bile ducts injuries during laparoscopic cholecystectomy. The arterial supply of extrahepatic bile ducts is delicate and variable and should be considered when trying to prevent ischemic injuries to the bile ducts. Inflammation and the combination of inflammation and anatomical variation are thought to contribute to a dangerous situation in regard to eventual injury to the bile ducts and vascular structures during operative procedures. This paper explores these questions.
