PANCREAS
Retroperitoneal except for a small part of its tail
- Elongated, soft & lobulated structure at T12/L1 to L3
(mixed gland)
- Lies in Epigastrium mainly transversely across the posterior abdominal wall, posterior to the stomach between the duodenum on the right and the spleen on the left.
- Length : 15 cm -Weighs : 80 g
Lymphatic drainage:
- Efferent vessels follow arteries ultimately drain into celiac, superior mesenteric and pre-aortic lymph nodes
- tail and body lymphatics drain mostly into the pancreaticosplenic nodes
- neck and head drain more widely into nodes along the pancreaticoduodenal, superior mesenteric and hepatic arteries
-
Blood
- Arteries:
- Splenic: great pancreatic artery (arteria pancreatica magna), dorsal pancreatic arteries, dorsal pancreatic artery (arteria pancreatica caudis)
- From gastrodudenal : Superior pancreaticoduodenal (anterior and posterior branches)
- From SMA: inferior pancreaticoduodenal (anterior and posterior branches)
- Veins: - Correspond to arteries & drain into the portal system
Divided into :
Head
– Disc shaped
– Lies in concavity of duodenum
– Uncinate process : part of head that extends to the left behind the superior mesenteric
Neck: (1.5cm)
– Constricted portion
– Connects head to body
– Lies in front of beginning of portal vein
-
• Tail:
– Passes forward in the lienorenal ligament with Splenic vessels
– Comes in contact with hilum of spleen
– Tip of the tail is usually blunted and turned superiorly.
-
Nerve supply
-
- By sympathetic (abdominopelvic splanchnic nerves) &
- parasympathetic (vagus ) nerve fibers
-
- Clinical
- Blockage of the hepatopancreatic ampulla and pancreatitis
- Accessory pancreatic tissue
- Pancreatectomies
- Rupture of the pancreas
- Pancreatic cancer
