Stomach, Liver, Pancreas, Duodenum, and Gallbladder, Posterior View

Description

Oriented from a posterior aspect in an adult male, the ventriculus (stomach) lies in the left upper quadrant with its posterior surface facing the viewer, while the hepar (liver) occupies a more superior and right-sided position, its visceral (inferior) surface approaching the lesser curvature region. Inferior to the stomach, the pancreas extends transversely in a retroperitoneal plane, with the head nestled within the C-shaped duodenum and the body and tail coursing leftward toward the splenic region. The vesica fellea (gallbladder) appears on the hepatic visceral surface, with the cystic duct joining the hepatic duct to form the common bile duct as it descends toward the second part of the duodenum. Relations read cleanly from medial to lateral and from superior to inferior. Posterior views like this earn their keep because they clarify what sits behind the stomach and what stays fixed in the retroperitoneum when the gaster is mobilized. It is the perspective you want when teaching why pancreatic carcinoma in the head of the gland can obstruct the distal bile duct and produce painless jaundice, or when explaining the anatomical basis for referred back pain in pancreatitis. Surgeons also think this way during a Kocher maneuver, when the duodenum is reflected medially to expose the pancreatic head, bile duct, and adjacent vascular planes. Use this illustration for upper gastrointestinal anatomy labs, hepatobiliary surgery chapters, and radiology teaching files that correlate ERCP or MRCP findings with the course of the pancreatic duct and extrahepatic biliary tree. It also fits well in patient-education materials for gallstones, cholecystitis, and pancreatoduodenectomy discussions, where the spatial relationship between gallbladder, ducts, and duodenum needs to be unambiguous.
