Pancreas Flashcards
Most commonly performed surgery to remove tumors in the pancreas
Whipples procedure
Surgical maneuver to expose structures in the retroperitoneum behind the duodenum and pancreas
Kochers maneuver
Pancreas weight in adult
75-100g
Pancreas length in adult
15-20 cm
Just behind the head of the pancreas lie
- the vena cava,
- the right renal artery,
- and both renal veins
Neck lies directly over the
Portal vein
Neck overlies in vertebral body of
L1 and L2
At the inferior border of the neck
superior mesenteric vein joins the splenicvein as the portal vein
Body and tail lie just anterior to the
Splenic artery and vein
Uncinate process wrap around the right side of the
Portal vein
Uncinate process end posteriorlynear the space betweenthe ____________ and ____________
Superior messentery artery and vein
Venous draining the pancreatic head and uncinateprocess enter along the ___________ and ____________ of the portal vein
Right lateral
Posterior sides
from the ventral bud connects to the bile duct
Ducts of wirsung
from the larger dorsal bud connects to the duodenum
Ducts of santorini
persist as a blind accessory duct -or drain through the lesser papilla
Ducts of santorini
Majority drains in to the major papilla
Ducts of wirsung
In a minority, ducts remain separate, and the majority of the pancreas drains through the duct of Santorini, a condition referred to as
Pancreas divisum
Inferior part of the pancreatic head and posterior to the superior messenteric artery
Uncinate process
Posterosuperior surface of the head
Bile duct
Adjacent to the pylorus of the stomach
Neck of pancreas
Lies to the left of the superior mesenteric vessels.
Posterior to the omental bursa
Body of the pancreas
Anterior to the left kidney
Tail of the pancreas
Begins in the tail of the pancreas and runs through the parenchyma to the pancreatic head
Main pancreatic duct
Pancreatic duct and bile duct unite
Hepatopancreatic ampulla
Blood supply of the body and tail
Splenic artery
Blodd supply of the head
Anterior and posterior superior pancreaticoduodenal artery.
Anterio and posterior inferior pancreaticoduodenal artery.
Origin of anterior and posterior superior pancreaticoduodenal artery
Gastroduodenal artery then from common hepatic artey from celiac trunk
Origin of anterior and posterior inferior pancreaticoduodenal artery
SMA
Drainage of pancreas
Splenic vein and superior messenteric vein from portal vein
Lymphnodes of pancreas
Pancreaticosplenic lymphnodes(most) Pyloric lymph ode( some)
Drainage of lymphnodes
Superior messenteric lyph nodes, celiac lymphnodes ia hepatic lymph node
Nerves of pancreas
Vagus and abdomini pelvic splanchnic nerve
Para and sympa fibers of pancreas
Celiac plexus
Superior messenteric plexus
From the splenic artery
Dorsal Pancreatic artery, •Great Pancreatic artery •Caudal pancreatic artery
Veins usually ________ to the arteries
Superficial
Venous branches draining the pancreatic head and uncinateprocess enter along the ____________ and _______________ of the portal vein
Right lateral
Posterior side
Antero/posterosuperior pancreaticoduodenal vein to
Portal vein
Antero/poster0inferior pancreaticoduodenal vein to
Superir messenteric vein
Lymphaticscommunicate with lymph nodes in the transverse mesocolonand mesentery of
Proximal jejunum
rich supply of afferent sensory fibers that travel superiorly to the
Celiac ganglia
Interruption of these somatic fibers with a ________________ can interfere with transmission of pancreatic pain
Celiac plexus block
Ultrasound •Pancreas is anterior to the two vessels identified
Portal vein and splenic vein
PARASYMPATHETIC INCREASES SECRETION OF
Insulin and glucagon
SYMPATHETIC INCREASES
Glucagon but inhibit insulin
