evaluates function of mouth, pharynx, larynx, and upper esophagus
What are some indications in a swallowing dysfunction study
Aspiration
Dysphagia
What is a Barium swallow/esophagram
evaluates structures and functions of entire esophagus down to the stomach
What are indications of an esophagram/barium swallow
Achalasia
Reflux/GERD
Dysphagia
Zenkers
What is achalasia
“without relaxation”
dissension of lower esophagus due to inability of food to pass into stomach
What is reflux/GERD
stomach acids in esophagus can cause damage
What is the valsalva maneuver
Big breath and bearing down land push like you’re pooping
What is zenkers diverticulum
pouch at the junction of the lower pharynx and esophagus
What overheads are needed for an esophagram
AP/PA
Lateral
LPO/RAO (40 degrees): places esophagus and stomach parallel to IR and off the spine
What anatomy is an upper GI looking at
The stomach
-fundus
-body
-greater curvature
-lesser curvature
-body
-pylorus
-duodenum
What is the patient prep for an upper GI
Dietary: NPO midnight/8 hours prior & no gum and cigarettes
Patient prep: gown from waist up, remove bra, necklace, etc.
What is needed in an upper GI

What are some indications for an Upper GI
hiatal hernia
schatzki ring
ulcers
dysphagia
bezoar
Define schatzki ring
a ring of tissue found in the lower part of the esophagus
Define an ulcer
erosion through lining of stomach
define Bezoar
mass of undigested material trapped in the stomach
