ANP 330 Lecture Notes - Lecture 62: Rapid Urease Test, Urea Breath Test, Gastric Outlet Obstruction
Document Summary
Dx measures depends upon presence & location of peptic ulcer. Endoscopy-view entire gastric & duodenal mucosa, determine degree healing after. Cytology & blood work (h-pylori, cbc, liver enzymes, serum amylase) cytology: igg, serum or whole bld antibody tests called igg. Upper gi series ( barium swallow)- beneficial dx gastric outlet obstruction ( barium swallow)- are not accurate although widely used as barium fails to fill the ulcer craters. X-rays are also ineffective as in differientiating peptic ulcer from ca. Dx gastric outlet obstruction - 50% barium remains on follow-up fils 6 hours later. Gastric analysis identifying zollinger-ellision syndrome, degree gastric hyperacidity. Pancreatic function in pts whom posterior penetration pancreas suspected. The diagnostic standard for pud is the egd (95% sen- sitivity). Biopsies for histopathology (93%-99% sensitivity and 95%-99% specificity) and a rapid urease test (89%-98% sensitivity and 93%-98% specificity) for detection of h pylori can be performed during the procedure. Histopathology is the criterion for the diagnosis of.
