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
