Posterior Perspective of the Gallbladder

Description

Posteriorly, the gallbladder lies in a fossa on the visceral (inferior) surface of the liver, with the fundus directed anteroinferiorly and the neck turning medially to continue as the cystic duct. Proximal to that junction, the right and left hepatic ducts unite to form the common hepatic duct, and the cystic duct joins it to create the common bile duct descending inferiorly toward the second part of the duodenum. Smooth serosa covers the free surface of the gallbladder, while the hepatic surface is apposed to liver parenchyma. Orientation is clear. This posterior perspective is the one you want when teaching how extrahepatic biliary anatomy relates to operative planes. During laparoscopic cholecystectomy, misidentification of the cystic duct and common hepatic duct near Calot’s triangle is a common mechanism of iatrogenic bile duct injury, and a rearward mental model helps explain why a low cystic duct insertion or a short cystic duct can collapse the safe window for clipping. The course of the common bile duct also frames discussions of obstructive jaundice from choledocholithiasis, where a stone lodged distally produces upstream ductal dilatation. Use this artwork in hepatobiliary anatomy labs, general surgery teaching files, and textbook figures on biliary obstruction, cholecystitis, and cholecystectomy technique, where a clean posterior view reduces ambiguity in duct naming and confluence patterns.
