Gallbladder of an Elderly White Male

Description

Centered in the right upper quadrant, the gallbladder (vesica biliaris) lies on the visceral (inferior) surface of the liver, typically between the right and quadrate lobes, with its fundus projecting anteroinferiorly toward the anterior abdominal wall. Proximally, the neck continues as the cystic duct, which joins the common hepatic duct to form the common bile duct coursing inferiorly toward the second part of the duodenum. Surrounding digestive viscera are visible through the semi-transparent body wall, including the esophagus descending to the stomach, with small-intestinal loops centrally and the large intestine framing them peripherally. Green lymphatic vessels and regional lymph nodes track along the abdominal viscera, aligning with expected drainage pathways of the hepatobiliary and gastrointestinal systems. Aging anatomy matters here. In an elderly male, gallbladder disease often presents as cholelithiasis with acute cholecystitis, and this view supports teaching the anatomic basis of right upper quadrant pain, Murphy sign, and referred pain patterns via adjacent peritoneum and diaphragm. Surgical relevance is immediate: the relationship of the gallbladder neck and cystic duct to the common hepatic duct anticipates Calot triangle dissection during laparoscopic cholecystectomy, where misidentification can injure the bile duct. Short and clear. Course directors can place this image in gross anatomy and GI blocks to orient students to hepatobiliary topography, then pair it with ultrasound or MRCP teaching on biliary obstruction and ductal dilation. Medical publishers will also find it suited to patient education on gallstones, cholecystitis, and biliary drainage, with the lymphatic overlay supporting discussions of regional nodal spread in gallbladder carcinoma.
