Exploration of liver, gall bladder, pancreas, duodenum and spleen

Uncinate process of pancreas elevated; pancreatic arteries

The inferior mesenteric vein and artery (4,17) and the uncinate process of the pancreas (21) have been lifted to display a part of the vascular supply to the head of the pancreas. Several arterial arches are visible which provide anastomoses between the gastroduodenal artery and branches of the superior mesenteric artery.

1. Superior part of duodenum (cut across)
2. Gastroduodenal artery
3. Duodenal and pyloric branches of gastroduodenal artery
4. Right gastroepiploic artery
5. Pancreaticoduodenal branches of gastroduodenal artery
6. Head of pancreas
7. Descending part of duodenum
8. Common bile duct
9. Hepatic plexus
10. Portal vein
11. Proper hepatic artery
12. Anastomotic branch between gastroduodenal and superior mesenteric arteries
13. Body of pancreas
14. Superior mesenteric vein (elevated and cut off)
15. Inferior pancreatic artery (a branch of middle colic artery in this specimen)
16. Middle colic artery (cut off)
17. Superior mesenteric artery (cut off and elevated)
18. Superior mesenteric plexus
19. Inferior pancreaticoduodenal artery
20. Superior mesenteric lymph node
21. Uncinate process of pancreas (elevated)
22. Ascending part of duodenum
23. Straight artery
