Methods of Evaluation Flashcards
studies fill the lumen with radiopaque material and are useful in the outlining of structures
single-contrast
small amount of high-density barium coats the mucosal surface and gas distends the organ and enhances contrast
double-contrast studies
scans cant test function as well as well as visualize the upper part of the GI tract up to the duodenum
esophagogastroduodenoscopy and HIDA
difficulty swallowing
dysphasia
painful swallowing
odynophagia
failure of a hypertensive LES to relax and the absence of esophageal peristalsis
achalasia
normal peristaltic rhythm with EXCESSIVE contractile force
nutcracker esophagus
UNCOORDINATED peristaltic waves
diffuse esophageal spasm (DES)
GERD leads to ___ which leads to ____
esophagitis
esophageal cancer
dilation of the submucosal veins secondary to portal hypertension.
esophageal varices
elevated portal venous pressure is greater than ____ which distends the veins proximal to the site of the blockage
> 10 mmHg
test that measure peristaltic contraction at the upper esophageal sphincter, esophageal body, and lower esophageal sphincter
manometry
x-ray study taken immediately after the patient swallows barium sulfate and baking soda
double contrast barium swallow/upper GI study
narrowing or corkscrew appearance
axial image may demonstrate thickening of esophageal wall (> 3 MM)
CT scan
study in which an ultrasound is moved through the extent of the esophagus can test the sensory and motor dysfunction
catheter based high frequency intraluminal ultrasound
