Anatomical Structure of the Gallbladder Base

Description

Arising from the visceral surface of the liver, the gallbladder is presented in close-up with emphasis on its base (fundus) and adjacent body, the serosa transitioning into the peritoneal reflections along the hepatic fossa. Inferior and slightly anterior to the right lobe, the gallbladder narrows proximally into the neck, which continues medially as the cystic duct toward the common hepatic duct to form the common bile duct. A rim of connective tissue and pericholecystic fat outlines the cholecystic bed, clarifying the plane between gallbladder adventitia and hepatic parenchyma. Orientation stays tight and surgical. This focus matters because the fundus and neck define the traction points and dissection planes during laparoscopic cholecystectomy, where exposure of Calot’s triangle and identification of the cystic duct must precede clipping and division. A stone impacted at the gallbladder neck or cystic duct (Hartmann’s pouch region) can distort anatomy, increasing the risk of common bile duct injury and complicating attainment of the critical view of safety. Acute cholecystitis often thickens the wall and blurs the gallbladder-liver interface, so a clear depiction of the base and its connective tissue attachments supports safe operative teaching. Ideal for hepatobiliary anatomy modules, surgical skills courses, and atlas figures accompanying chapters on biliary colic, cholelithiasis, and cholecystectomy technique, this close-up also works well in patient-facing materials that need accurate spatial relationships without a full abdominal overview.
