Posterior Perspective Focusing Upon the Neck of the Gallbladder

Description

Arising from the inferior surface of the right lobe of the liver, the gallbladder is presented from a posterior perspective with attention centered on its neck, the tapered segment that curves superiorly and medially to become continuous with the cystic duct. Posteriorly, the neck sits adjacent to the hepatic parenchyma, while the body of the gallbladder extends more inferiorly and laterally within its fossa. The cystic duct departs the neck toward the porta hepatis, positioning the biliary outflow pathway medial to the gallbladder fundus and body. Focusing on the gallbladder neck matters because this short segment is the anatomic choke point where pathology concentrates and where surgeons earn their margin of safety. Gallstones often lodge at the neck or within the infundibulum (Hartmann pouch), producing acute cholecystitis and, when the stone compresses the common hepatic duct, Mirizzi syndrome with obstructive jaundice. This posterior angle also supports teaching of the cystic duct trajectory toward the extrahepatic biliary tree, a relationship that underpins safe dissection of Calot triangle during laparoscopic cholecystectomy and helps explain how misidentification can lead to common bile duct injury. A small region. Big consequences. Use this artwork in hepatobiliary anatomy labs, surgical education modules on critical view of safety, and publisher figures discussing cholelithiasis, cholecystitis, or biliary obstruction pathways. It also fits radiology teaching when correlating operative anatomy with ultrasound or MRCP descriptions of cystic duct and gallbladder neck caliber.
