What is the pancreas?
• An elongated, acessory digestive gland that lies retroperitonealy.
At what verterbral level can you find the pancreas?
• L1 + L2
Where does the pancreas lie in relation to other organs?
• Posterior to the stomach • Between the duodenum and the spleenTransverse mesocolon attaches to its anterior margin
What are the four parts of the pancreas?
• Head • Neck • Body • Tail
Where can the head of the pancreas be found?
• In the C-shaped curve of the duodenum
What does the neck of the pancreas overly?
• Superior mesenteric vessels
Where does the main pancreatic duct begin?
• At the tail of the pancreas and runs through the glans to the head • Then turns inferiorly and is closely related to the bile duct
What do the pancreatic duct and bile duct join together to form?
• Hepatopancreatic ampulla of vater which opens into duodenum
Where is the arterial supply of the pancreas derived from?
• Branches of the splenic artery
What two arteries do the pancreatic arteries form arches with?
• Gastroduodenal • Superior mesenteric arteries
Where does the splenic artery come from? List the arteries leading to pancreastic arteries
Coeliac trunk -> Splenic artery -> Pancreatic
What are the names of the gastroduodenal arterial supply of the pancreas?
• Anterior and posterior superior pancreaticoduodenal arteriesAnterior and posterior inferior pancreaticoduodenal arteries
What are the names of the superior mesenteric arterial supply to the pancreas?
• Pancreaticoduodenal arteries form anteriorly and posteriorly placed arches that supply the head
What is the venous drainage of the pancreas?
• Pancreatic veins which correspond to arterial supply • Pancreaticoduodenal veins are the main one • Empty into splenic vein and superior mesenteric vein
Describe the spleen
• An ovoid, purplish pulpy mass about the size and shape of a fist • Delicate
Where is the spleen located?
• Upper left quadrant or hypochondrium of the abdomen, resting on left colic flexture ?
What is the spleen covered by, and what is the only exception to this?
• Layer of visceral peritoneum, except at the splenic hilum
What are the anterior relations of the spleen? What is the attachement?
• The stomach • Attached by the gastrosplenic ligament
What is the posterior relation of the spleen
• The left part of the diaphragm, which separates it from the pleura, lung and ribs 9-11
What is the inferior relation of the spleen?
The left colic flexure
What is the medial relation of the spleen? What is the attachment?
• The left kidneyAttached by the splenorenal ligament
What is the arterial supply of the spleen?
• Splenic artery, the largest branch of the coeliac trunk
What is the course of the splenic artery?
• Travels posterior to the omental bursa, anterior to the left kidney and along the superior border of the pancreas
What is the venous drainage of the spleen?
• Splenic vein • Drains into Inferior mesenteric vein which runs posterior the body and tail of the pancreas throughout most of its course
