Gallbladder of an Obese White Male

Description

Posteriorly, the right upper quadrant is rendered with a transparent body wall to localize the hepatobiliary organs within an obese adult male. The liver occupies the right hypochondrium beneath the inferior ribs, and the gallbladder (vesica fellea) sits on its visceral (inferior) surface, right of midline and anterior to the right kidney. From the gallbladder neck, the cystic duct courses medially to join the common hepatic duct, forming the common bile duct that descends toward the second part of the duodenum, while the branching intrahepatic bile ducts spread superiorly within the hepatic parenchyma. Portions of both lungs appear superiorly in the thorax, with the intestinal loops shown inferiorly in the abdomen to anchor overall topography. Obesity changes operative anatomy, and this rear-oriented localization helps explain why laparoscopic cholecystectomy can become more technically demanding when the abdominal wall is thick and the liver is enlarged or steatotic. Orientation of the cystic duct toward the common hepatic duct matters because misidentification in Calot’s triangle is a classic mechanism for common bile duct injury, and ductal variants become harder to appreciate when landmarks are obscured by fat. Biliary colic, acute cholecystitis, choledocholithiasis, and gallstone pancreatitis all trace back to these ductal relationships. Use this asset in gross anatomy and GI blocks to teach organ topography and the biliary tree, or in surgical education materials that introduce port placement rationale and duct identification before dissection. It also fits patient-facing or institutional content explaining gallbladder disease risk in obesity and the pathway of bile from liver to duodenum.
