Gallbladder, Pancreas, and Duodenum, Anterior View

Description

Framed by the inferior ribs and anterior vertebral column, the gallbladder lies in the right upper abdomen, inferior to the liver and lateral to the proximal duodenum, with the cystic duct joining the common hepatic duct to form the common bile duct. The duodenum forms its characteristic C-shape, wrapping around the head of the pancreas, while the pancreatic neck and body extend medially and leftward across the posterior upper abdomen. Green biliary channels course inferiorly toward the second part of the duodenum, converging near the pancreatic head where the distal common bile duct approaches the pancreatic parenchyma. Relationships are the point. For teaching upper gastrointestinal anatomy, an anterior perspective clarifies why pancreatic and biliary disease often present together: the intrapancreatic segment of the distal common bile duct can be narrowed by edema or a mass in the pancreatic head, producing painless jaundice in pancreatic carcinoma or fluctuating obstruction with pancreatitis. The same regional anatomy underlies gallstone pancreatitis, when a migrating calculus transiently blocks the hepatopancreatic ampulla (ampulla of Vater) at the major duodenal papilla, interrupting bile flow and pancreatic exocrine drainage. That C-loop of the duodenum around the pancreatic head is also a key landmark for the Kocher maneuver and for orienting pylorus-preserving pancreaticoduodenectomy. Use this plate for gross anatomy and GI blocks when you need learners to connect the biliary tree to the pancreas and duodenum, or for surgical and radiology texts that discuss obstructive jaundice, ERCP access, and periampullary pathology in adult male anatomy.
