Final GB PAN Flashcards
Cholelithiasis
- gallstones. Usu CHL (must be 80%)
- Mixed >19%; pigment
gallstones
90% radioluscent do’t show on x-Ray) vs. nephrolithiasis (90% show)
acute acalculous cholecystitis
obstrution, CAD, trauma, immunosuppressive
chronic cholecystitis
- GB wall thickens
- shaggy appearance
- rokitansky-Aschoff bodies
cholestorolosis
- deposit of CHL and TG filled mO in LP of GB
- hundreds of tiny bright yellow dots (foci of CHL)–>strawberry GB
procelain GB
- calcification d/t persistent inflammation
- risk factor for GB CA
choledocholithiasis
gallstone that has passed into common bile duct
ascending cholangitis
- bacteria Infx ascending
- pus in ampulla of Vater
- peri-ductal fibrosis (ONION SKINNING) indistinguishable from PSC.
GB carcinoma
- poor prognosis
- F:M ratio 2-4:1; age 70
- Most likely ADENOCARCINOMA (well differentiated most common)
- tubular glands
Acute pancreatitis
- F: gallstone related. M: ETOH related
- Complication: abscess
- saponification of calcium salts and FA
- labs: amylase and lipase
pseudocyst
- NO EPITHELIAL lining
- NOT a tumor
- peri-pancreatic fluid collection w/ high concentrations of pancreatic enzymes
Infected Necrosis
bac contamination of necrotic pancreatic tissue; abscence of ABSCESS
pancreatic access
- pus from tissue necrosis, liquefaction, infection
- late complication of acute necrotizing pancreatitis
- E. Coli, klebsiella, s. aureus, streptococcus, pseudomonas
What are the benign pancreatic tumors
- pseudo papillary
- serious cyst adenoma
- muciloys cystadenmoma
pseudo papillary
hist: sheets of cells w/ uniform nuclei and eosinophilia or clear cytoplasm
serious cyst adenoma
- honeycombed appearance on CT
- ciliated cuboidal epithelium
- Von Hippel-Lindau syndrome
mucilinous cystadenoma
can transform into malignant if left untreated.
F>M, 49-59
What are the malignant tumors of the pan.
- Pancreatic adenocarcinoma
2. mucious cystademocarcinoma
pancreatic adenocarcinoma
- EXOCRINE component, mostly from DUCTS (99%)
- VERY poor prognosis
