Detail the anatomy of the extrahepatic biliary tree.
|
R and L hepatic duct unit to form the short common hepatic duct. The cystic duct joins that and the become the longer portion called the common bile duct. The common bile duct has a supraduodenal portion that lies above the inserts of the pancreas. This is good to keep in mind in terms of pancreatitis and neoplastic conditions of the pancreas can cause strictures and such resulting in possibly jaundice.
The common bile duct and pancreatic duct meet at the ampulla of Vader. Gallbladder concentrates and stores bile. Gallblader lies along the later portion of the duodenum and the posterior inferior surface of the liver and hepatic flexture of the stomach. |

True or False:
In embryology learned that the pancreas is comprised of two parts that come together to form one. And there are thus the principal pancreatic duct and an accessory pancreatic duct. The principal is the main larger one, and the accessory is a small offshoot but that may or may not connect to the duodenum. |
True!

|
True or False:
Brown earthy colored gall stones are due to calcium bilirubinate and hemolytic conditions. |
FALSE.
That description is of BLACK STONES. Brown earthy stones are of caclium salts of fatty acids (soaps), billirubin, or due to chronic bile stasis with bacterial colonization. |
|
|
Which of the following is true about adenocarcinoma of the gallbladder?
A. Strong association with gallstones (80-90%) B. Tumor of older women (3:1 female:male) C. Presents late D. 5 year survival rat is about 25% |
FALSE IS
D. 5 year survival rat is about 25% - it is actually 4%!!!! |
|
|
What condition is described?
Chronic, progressive, fibro-inflammatory disease of the extrahepatic, and often the intrahepatic, biliary system. Idiopathic. Occurs in the absence of biliary calculi or previous biliary tract surgery. 50% of cases associated with ulcerative colitis. Incidence: Uncommon. A. Choledocholithiasis B. Cholecystoduodenal Fistula C. Primary Sclerosing Cholangitis D. Adenocarcinoma of the Extrahepatic Bile Ducts |
C. Primary Sclerosing Cholangitis

Acute hemorrhagic pancreatitis is enzymatic destruction of the pancreatic and peri- pancreatic tissues with accompanying inflammation. What specifically does trypsin, elastase and lipase do?
|
Trypsin: Proteolytic destruction of pancreatic parenchyma
Elastase: Necrosis of blood vessels with subsequent hemorrhage Lipase: Fat necrosis |
|
