Pancreas Flashcards
What are the cells of the pancreas that carry out the exocrine function and produce amylase, lipase and sodium bicarbonate?
Acinar cells
What is chyme?
Partially digested food
What is in the double duct sign?
Enlarged CBD and pancreatic duct
What’s the accessory duct of the pancreas?
Duct of Santorini
A gastrinoma is a:
islet cell tumor
What are the islands of tissue found within the pancreas that produce insulin and glucagon?
Isles of Langerhans
What’s the most common cancer of the pancreas?
Pancreatic adenocarcinoma
Difference between pseudocyst and phlegmon?
Psuedocyst - pancreatic enzymes that have leaked into the tissue surrounding the pancreas
Phlegmon - peripancreatic fluid collect that results in the inflammation of the pancreas
What’s von Hippel Lindau disease?
a hereditary disease that includes the development of cysts within the pancreas and other organs
What’s Zollinger-Ellison syndrome?
Excessive secretion of acid by the stomach caused by the presence of a functional gastrinoma within the pancreas
What supplies the head of the pancreas? What supplies the body and tail?
GDA
SA + SMA
Are serous cystadenomas benign or malignant?
Benign
Mucinous cystadenomas have malignant potential
Mucinous cystadenomas are found in the body and tail. True or false
True
Two types of islet cell tumors:
Gastrinoma
Insulinoma ** (mc)
The most common location of focal pancreatitis is:
Head
Which part of the pancreas is located anteriorly to the portal confluence?
Neck
Which part of the pancreas is located right lateral to the SMV, anterior to IVC and inferior to PV?
Head
One clinical sign of an insulinoma is?
Low blood sugar signs
A gastrinoma of the pancreas can produce:
Zollinger Ellison syndrome
Whipple procedure:
A surgical procedure in which the head of the pancreas, the gallbladder, some of the bile ducts and proximal duodenum are removed
Phlegmon:
the peripancreatic fluid collection that results from inflammation of the pancreas
What are the exocrine functions of the following? Amylase, lipase, sodium bicarbonate and trypsin/chymotrypsin/carboxypolypeptidase
Amylase- carbs
Lipase -fats
Sodium bicarb- neutralize stomach avid
Trypsin, etc. - proteins
What’s the functional unit of the endocrine component?
Isles of Langerhans
Endocrine functions:
Insulin- stimulates the body to use glucose for energy
Glucagon- promotes release of glucose
Panc head blood supply
GDA
Panc body & tail blood supply
SMA & SA
Which pancreatic enzyme is raised first with acute pancreatitis?
Amylase, but does lipase last longer??
Focal pancreatitis is often seen where?
Head
What’s the more common site for a pseudocyst?
Lesser sac
When you see the double duct sign, what could this indicate?
Pancreatic adenocarcinoma
2 ducts – CBD + panc duct
Cystadenoma’s/cystadenocarcinomas are often found in:
Body & tail
True pancreatic cysts may be seen with:
Von Hippel-Lindau disease or ADPKD
All of the following are sonographic features of chronic pancreatitis except: dilated panc duct, calcifications within the pancreas, pseudocyst, and diffusely hypoechoic panc
Diffusely hypoechoic pancreas
Which lab value is more specific for acute pancreatitis?
Lipase
Which cells carry out the exocrine function of the pancreas? Whipple cells, Isles of Langerhans, Delta cells or Acinar cells
Acinar
A clinical sign of an insulinoma is:
low blood sugar symptoms
Which part of the pancreas is located right lateral to the SMV, anterior to IVC, and inferior to PV?
Head
Which part of the pancreas is located anterior to the portal confluence?
Neck
