● Pear shaped saccular structure for bile storage in gallbladder fossa of posterior right hepatic lobe
● Attached to liver by loose connective tissue; and to duodenum by cholecystoduodenal ligament
● 10 x 4 cm, but depends on volume of bile (normal 40-70 ml)
● Wall thickness 1-2 mm
● Has fundus, body and neck
● Distal fundus: extends beyond anterior liver margin
● Central body: most of gallbladder
● Neck: narrows as it joins the cystic duct
● Cystic duct: 3 cm tubular structure, located in right free edge of lesser omentum, has spiral valve of Heister
● Infundibulum: portion of body that joins the neck
● Hartmannís pouch: dilation in infundibulum, may be due to chronic inflammation
● Vasculature: supplied by cystic artery, usually a branch of right hepatic artery
● Note: variations of bile ducts and arteries may be dangerous during surgery
● Regional lymph nodes: lymph node present at gallbladder neck or cystic duct drains to hepatic hilar nodes (along common bile duct, hepatic artery, portal vein, cystic duct); also celiac, periduodenal, peripancreatic and superior mesenteric nodes
