Anatomy
High yield
Stomach: surgical anatomy
J-shaped foregut organ from the cardia (T11) to the pylorus (L1); antrum lacks parietal and chief cells.
High yield
Vagal innervation of the stomach
Anterior (left) and posterior (right) vagal trunks give hepatic, coeliac and gastric divisions; nerves of Latarjet supply the antrum.
High yield
Duodenum: surgical anatomy
C-shaped, 25–30 cm, from pylorus to duodenojejunal flexure around the pancreatic head; retroperitoneal except the first 2.5 cm.
High yield
Lymphatic drainage of the stomach and duodenum
Gastric lymph follows the arteries through 20 numbered stations to the coeliac nodes; duodenal lymph drains to pancreaticoduodenal nodes.
Morrison’s pouch
The hepatorenal pouch: a potential space between the liver and right kidney in the supramesocolic compartment.
Cantlie’s line: a brief overview
The plane that divides the liver into functional left and right lobes, central to hepatectomy.
