Duodenum, Pancreas, and Spleen, Anterior View

Description

Centered in the upper abdomen, the pancreas spans transversely with its head nestled within the C-shaped curve of the duodenum, while the body and tail taper leftward toward the splenic hilum. From an anterior perspective, the descending (second) part of the duodenum lies to the right of the pancreatic head, with the horizontal (third) part crossing inferiorly. Splenic vessels course along the superior border of the pancreatic body and tail before entering the spleen. Relationships read cleanly. Teaching the duodenum cradling the pancreatic head is more than orientation, it frames common clinical pain points. In acute pancreatitis, inflammatory fluid tracks in the peripancreatic planes and can irritate adjacent duodenum, while chronic disease may calcify along the pancreatic ductal system and distort the head region, complicating endoscopic access at the major duodenal papilla. The splenic artery’s tortuous path along the pancreas explains why distal pancreatic resections place it, and the splenic vein, at risk during mobilization near the tail. Use this illustration for gross anatomy and GI blocks when introducing foregut derivatives, or for surgical teaching materials on pancreaticoduodenectomy (Whipple) orientation and distal pancreatectomy with splenectomy versus spleen-preserving approaches. It also fits radiology primers that correlate anterior anatomy with CT landmarks of the pancreatic head, body, and tail relative to the duodenal sweep and splenic hilum.
