UGIS Flashcards
1
Q
the radiographic examination of the distal esophagus, stomach, and duodenum after the administration of contrast media
A
Upper Gastro Intestinal Series
2
Q
It requires 8oz. of BaSO4
A
UGIS
3
Q
What is the purpose of UGIS?
A
- distal esophagus
- stomach
- duodenum
- detect abnormal anatomic and functional conditions
4
Q
What are the Contrast Media used?
A
- Thin barium sulfate mixture
- Thick mixture of BaSO4
- Water soluble iodinated contrast media
5
Q
What are the types of examination?
A
- Single Contrast Examination
- Double Contrast Examination
- Biphasic/Dual Contrast/ Welin Technique Examination
- Hypotonic Duodenography
6
Q
- The barium sulfate suspension is administered during the initial fluoroscopic examination for this type of examination.
- The patient is given a glass of barium and instructed to drink it as directed by the technologist.
A
Single Contrast Examination
7
Q
- The technologist gives the patient a gas producing
substance in the form of powder crystals, a pill or carbonated beverage. - The patient is then given a small amount of high-density barium suspension, after which, the patient is instructed to turn from side to side or roll over a few times.
- Allow for greater distention of the stomach and bowel for improved visualization
- To relax the Gl tract.
A
Double Contrast Examination
8
Q
- The patient is first examined by performing a double contrast examination of the upper gastro intestinal tract.
- On completion, a single contrast examination.
A
Biphasic/Dual Contrast/ Welin Technique Examination
9
Q
- less frequently used examination
- useful for the detection of lesions in the duodenum distal to the duodenal bulb and for the diagnostic of pancreatic disease.
- involves passing a tube through the mouth or nose and into the duodenum after the administration
of glucagon to relax the GI tract and halt peristalsis. - Barium and air are injected through the tube via syringe to provide radiographic contrast
- the use of this study is declining.
- double contrast UGI examinations are most likely to be used for evaluation of the duodenal loop. Ultrasound, CT, needle biopsy or ERCP are used for pancreatic evaluation
A
Hypotonic Duodenography
10
Q
What are the Indications?
A
- To demonstrate gastric ulcer, duodenal ulcer, and peptic ulcer (a general term which means ulceration of the mucosal lining caused by pepsin).
- To demonstrate gastric varices and colics
- To demonstrate tumor and carcinoma
- To demonstrate any obstruction such as BEZOAR
- TRICHOTILLOMANIA
- To demonstrate gastritis
11
Q
a mass of undigested material that becomes trapped in the stomach
A
Bezoar
12
Q
- compulsive urge to pull out one’s hair
- may be triggered by depression or stress
- people with trichotillomania also ingest the hair that they pull
A
Trichotillomania
13
Q
What are the contraindications?
A
- sensitivity to the contrast media
- patient with history of bowel perforation laceration, and viscous rupture
14
Q
What are the patient preparation?
A
- Light evening meal
- NPO at midnight. No drinks or even smoking
- No breakfast until examination is finished
15
Q
- fundus of the stomach is the most posterior portion and therefore is where the heavy barium settles.
- Note the collection of gas in the body and pylorus of
the stomach.
A
Supine Position
