*incr WBC
*liver enzyes +/- increase
*mild hyperbilirubinemia
*hyperglycemia
*hypocalcemia

CHRONIC: calcifications on US/gallstones, amylase and lipase NOT elevated

A

  • put fiberoptic camera down into esophagus to visualize problem
  • SEE: high quality color imaging of esoph, gastric and duodenal LUMENS
  • can also do biopsies, injection catheters for delivery of drugs, balloon dilators or hemostatic devices

GOOD FOR: mucosal lesions, biopsies or interventional procedures are required (dilation, banding)

minimally invasive**

NOT GOOD FOR: looking at motion.. aka mobility disorders

Q

  • Good for?
  • cons?
  • high sensitivtiy for?
A
  1. XR — still
  2. Fluoroscopy—real time/moving XR

*contrast PO is needed so it illuminates inside esophagus “BARIUM SWALLOW”

GOOD FOR: function and morphology: strictures, compression and altered anatomy: reflux, hiatal hernias, mucosal granulairty, erosions, ulcerations, strictures

high sensitiity for detecting strictures vs endoscopy
CON:
-not good for looking at mucosa
-not fully diagnostic and PT will eventually need endoscopy—even if the esophagram study is negative …why???? because next step would be to obtain biopsies, provide tx, or clarify any abnormal findings in case of + exam OR to add certainty to a - exam
