Gallbladder Flashcards
Extends from the point where the common hepatic duct meets the cystic duct; drains into the duodenum after it joins with the main pancreatic duct
CBD
Storage pouch for bile
Gallbladder
Small opening in the duodenum in which the pancreatic and CBD enter to release secretions
Ampulla of Vater
Massive enlargement of the gallbladder
Hydrops
Tiny valves found wi the CD
Heister’s valve
Refers to CBD and CHD when cystic duct is not seen
Common duct
Connects the gallbladder to the CHD
Cystic duct
Central area of the liver where the portal vein, common duct, and hepatic artery enter
Porta hepatis
Small portion of the gallbladder that lies near the cystic duct where stones may collect
Hartmann’s pouch
Travels horizontally through the pancreas to join the CBD at the ampulla of Vater
Pancreatic duct
Small muscle that guards the ampulla of Vater
Sphincter of Oddi
Yellow pigment in bile formed by the breakdown of rbc’s
Bilirubin
Removal of gallbladder
Cholecystectomy
Gallbladder fundus is bent back on itself
Phrygian cap
Bile duct system the drains the liver into the CBD
CHD
Gallstones in the gallbladder
Cholelithiasis
Calcification of gallbladder wall
Porcelain gallbladder
Inflammation of the bile duct
Cholangitis
Small polyploid projections from the gallbladder wall
Adenomyomatosis
Sonographic pattern found when the gallbladder is packed with stones
Wall echo shadow ( WES) sign
Cancer at the bifurcation of the hepatic ducts; may cause asymmetrical obstruction at the biliary tree
Klatskin’s tumor
Low level echoes found along the posterior margin of the gallbladder; move with change in position
Sludge
Hormone secreted into the blood by the mucosa of the upper small intestine; stimulates contraction of the gallbladder and pancreatic secretion of enzymes
Cholecystokinin
Variant of adenomyomatosis; cholesterol polyps
Cholesterolosis
Inflammation of the gallbladder; acute or chronic
Cholecystitis
Cystic growth on the common duct that may cause obstruction
Choledochal cyst
Small septum wi the gallbladder, usually arising from the posterior wall
Junctional fold
Small, well defined soft tissue projection from the gallbladder wall
Polyp
Stones in the bile duct
Choledocholithiasis
An uncommon cause of extrahepatc biliary obstruction as a result of an impacted stone in the cystic duct creating extrinsic mechanical compression of the CHD
Mirrizi syndrome
What causes increasing pressure in the biliary tree with pus accumulation
Cholangitis
Multiple cystic structures that converge toward the porta hepatis are seen as what
Caroli’s disease
