Anatomy of the Pancreas
Lies anterior to the first and second lumbar bodies located deep in the epigastrium and left hypochondrium, behind the lesser omental sac.
Major posterior vascular landmarks of the pancreas
aorta and IVC
Majority of the pancreas lies in the
Posterior to the pancreas
portal-splenic confluence, superior mesenteric vessels, aorta, inferior vena cava, and lower border of the diaphragm.
Stomach, duodenum, and transverse colon form the superior and lateral borders of the
Four areas of the pancreas
head neck body and tail
Head of the Pancreas
Lies anterior to the inferior vena cava, to the right of the portal-splenic confluence, inferior to the main portal vein and caudate lobe of the liver, and medial to the duodenum as it "lies in the lap" of the C-loop of the duodenum
The splenic vein forms the posterior medial border of the
superior mesenteric vein crosses anterior to the uncinate process of the head of the gland and posterior
to the neck and body of pancreas
uncinate process is the small, curved tip at
the end of the head of the pancreas.
Neck of the Pancreas
Found directly anterior to the portal-splenic confluence or superior mesenteric vein
Body of the Pancreas
Anterior to the aorta and celiac axis ,left renal vein, adrenal gland, and kidney
The anterior border is the posterior wall of the
antrum of the stomach.
The neck of the pancreas forms the
right lateral border.
Splenic vein is the posterior border of
the body and tail of pancreas
Splenic artery forms the
superior border of the tail of panc
Stomach is the
anterior border of the tail of panc
Duct of Wirsung
Primary duct, extending the entire length of the gland
Duct of Santorini
Secondary duct that drains the upper anterior head
normal size of pancreas
Head <3 cm; neck <2.5 cm; body <2.5 cm; tail <2.0 cm
Ectopic pancreatic tissue
inflammation of the pancreas.
May be classified as acute or chronic.
Is further classified as mild to severe.
the pancreatic tissue may be digested by its own
enzymes, when pancreatitis occurs
A collection of fluid that arises from the loculation of inflammatory processes, necrosis, or hemorrhage.
Develops when pancreatic enzymes escape from the gland and break down tissue to form a sterile abscess somewhere in the abdomen.
Locations of a Pseudocyst
Most common location is in the lesser sac anterior to the pancreas and posterior to the stomach.
2nd common anterior pararenal space
Pancreatic ascites occurs when
the pancreatic pseudocyst ruptures into the abdomen.
is an inflammatory process that spreads along fascial pathways, causing localized areas of diffuse inflammatory edema of soft tissue that may proceed to necrosis and suppuration.
Most common primary neoplasm of the pancreas
fourth most common cause of cancer-related mortality
Adenocarcinoma clinical symptoms
Tumors in the pancreatic head present symptoms early.
Two types of cystic neoplasm
Microcystic adenoma (serous cystadenoma)
Macrocystic adenoma (mucinous cystadenoma/cystadenocarcinoma)
