Gallbladder of an Obese Male

Description

Anterior abdominal wall transparency reveals the right upper quadrant hepatobiliary anatomy in an obese adult male standing in anatomical position. The liver occupies the superior right hypochondrium, with the gallbladder (vesica biliaris) lying on its visceral (inferior) surface, slightly to the right of the midsagittal plane, and tapering from a fundus projecting anteriorly and inferiorly into a narrower body and neck. From the neck, the cystic duct courses medially to join the common hepatic duct, forming the common bile duct that descends posterior to the first part of the duodenum toward the head of the pancreas. Pear shaped. Obesity changes the clinical conversation around this organ, because cholesterol supersaturation and gallbladder hypomotility increase the prevalence of cholelithiasis and acute cholecystitis, and a thickened abdominal wall can complicate physical examination and operative access. Clear depiction of the gallbladder’s relationship to the inferior liver margin and extrahepatic biliary tree supports teaching of pain referral patterns and the limits of sonographic windows, where ribs, bowel gas, and adipose tissue commonly degrade image quality. It also frames the procedural anatomy behind laparoscopic cholecystectomy, where safe identification of the cystic duct and cystic artery within Calot’s triangle reduces the risk of common bile duct injury. Use this asset in gross anatomy and GI/hepatobiliary blocks to orient students to surface anatomy and organ position in the obese habitus, and in surgical education materials introducing biliary colic, acute cholecystitis, and postoperative bile leak. It also fits patient facing handouts for bariatric or general surgery clinics when counseling about gallstones and cholecystectomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
