Pancreas is divided into 4 areas
- Small curved top at the end of the head of the pancreas
- Anterior to the IVC
- Posterior to the SMV
- Most inferior portion
- Anterior to the IVC
- Right of the portal splenic confluence
- Inferior to the main portal vein and caudate lobe of the liver.
- Medial to the duodenum as it is surrounded the C-loop of the duodenum
- Anterior to portal splenic confluence.
- Forms the right lateral border and is often included as part of the body.
Largest portion of the pancreas
- Anterior to the aorta, celiac axis, splenic artery, hepatic artery, and left gastric artery
- Anterior border is the posterior border of the antrum of the stomach
- Tortuous splenic artery is the superior border of the gland
- The splenic vein courses the posteriomedial surface of the pancreas to join the main portal vein.
- Located anatomically left near the hilum of the spleen and left border of aorta
- Lies anterior to the left kidney
- Posterior to the left colic flexure and transverse colon
- Ducts of Wirsung
- Duct of Santorini
Ducts of Wirsung
- Extends the entire length of the gland
- Receives tributaries from lobules at right angles and enters the medial second part of the duodenum with the CBD at the ampulla of Vater
Duct of Santorini
- Secondary duct
- Drains the upper anterior portion of the head
- Enters the duodenum at the minor papilla about 2cm proximal to the ampulla Vater
1. Head of Pancreas
2. Uncinate process of the pancreas
3. Pancreatic Notch
4. Body of pancreas
5. Anterior surface of pancreas
6. Inferior surface of pancreas
7. Superior margin of pancreas
8. Anterior margin of pancreas
9. Inferior margin of pancreas
10. Omental tuber (bulge Lt of the SMA)
11. Tail of Pancreas
supplies the body and the tail of the pancreas
supplies the head and part of the duodenum
- Supraprancreatic PV
- Retropancreatic PV
- Splenic vein
- Infrapancreatic SMC
- All drain into the portal vein
Inferior mesenteric artery is also known as ?
inferior pancreaticoduodenal artery
seen anterolateral along the border of the pancreas divides into the superior pancreaticoduodenal branches and join the inferior pancreaticoduodenal branches which rise from the superior mesenteric artery
Measurement from head to tail
roughly about 15cm (range 12 to 18cms)
Measurement of the head of the pancreas
Measurement of the neck of the pancreas
Measurement of the tail of the pancreas
Measurement of the body of the pancreas
__________ is considered to be retroperitoneal
Small portion of the head of the pancreas is _______
Unlike the liver the pancreas is not ____________
simple squamous epithelial cells
- Pancreas Divisum
- Ectopic pancreatic tissue
- Annular pancreas
- Anomaly in the anatomy of the ducts of the pancreas in which a single pancreatic duct is not formed, but rather remains as two distinct dorsal and ventral ducts.
Ectopic Pancreatic Tissue
- MOST COMMON of the Anomalies
- Frequent sites: stomach, duodenum, small bowel, large bowel.
- Seen with other anomalies.
- Pancreas surround duodenum.
- Obstruction at birth.
- MORE COMMON IN MALES.
- Differential diagnosis: Pancreatic Divisum.
breaks down carbohydrate
breaks down lipids (triglycerides) into free fatty acids
are used to break down proteins by a change reaction of enzymes.
A serum amylase of twice the normal value is consistent with _________ ________
Islets of Langerhans
responsible for blood glucose homeostasis
- Produce GLUCAGON
- is a hormone produced by the pancreas that stimulates an increase in blood sugar levels, thus opposing the action of insulin.
- MOST COMMON
- Produce INSULIN, which causes glycogen formation from glucose in the liver.
- Inhibits the production of both INSULIN and GLUCAGON
- Level of twice normally indicates ACUTE PANCREATITIS.
- It is also secreted by the pancreas, parotid glands and gynecologic system and bowel.
- Urine amylase may be elevated in pancreatitis
- Excreted specifically by the pancreas
- Parallels elevation of amylase
- Elevation with obstruction of the pancreatic duct, acute cholecystitis, and pancreatic carcinoma
- Controls blood sugar
- Found in abundance in diabetes, chronic liver disease
- They may be a decrease blood sugar level in tumors of the largerhans
TRUE OR FALSE
Pancreas is isoechoic or hyper echoic to a normal sonographic liver texture
