Overview of Gastric Disease Flashcards
Most common symptoms of gastric disease.
Pain
Weight loss
Early satiety
Anorexia
How to rule out malignancy in patients diagnosed with gastric ulcer?
Multiple biopsy specimens of the base and rim of the lesion
Most serious complications of esophagogastroduodenoscopy (EGD)?
Perforation
Aspiration
Respiratory depression
Indications for plain abdominal xray in gastric disease.
Gastric perforation (pneumoperitoneum) Delayed gastric emptying (large air fluid level)
Indications for double contrast upper GI series.
Gastric diverticula Fistula Tortuosity Locating strictures Defining hiatal hernia size
Indications for MRI in gastric disease.
Quantitative test for gastric emptying
Analysis of Myoelectric derangements in gastroparesis
Indications for arteriography in gastric disease.
Exsanguinating gastric hemorrhage
Occult gastric bleeding
Indications for endoscopic ultrasound in gastric disease.
- Local staging of gastric adenocarcinoma
- Sampling suspicious nodes with EUS guided needle biopsy
- Endoscopic mucosal resection for malignant tumors confined to mucosa
- Detecting submucosal masses
- Submucosal varices
Indications for gastric secretory analysis.
Hypergastrinemia (Zollinger-Ellison Syndrome, GERD, refractory ulcer)
Normal basal acid output (BAO): >5mEq/h
MAO: Average of two final stimulated 15-min periods (10-15 mEq/h)
Gastrinoma BAO: >15meq/h, often above 30
(BAO-MAO ratio is 0.6)
Indications for scintigraphy in gastric disease.
Evaluation of gastric emptying Duodenogastric reflux (HIDA scan)
Tests for helicobacter pylori.
A positive test is presumptive evidence, but a negative test is unreliable.
Histologic exam of antral mucosal biopsy (Gold standard)
Rapid urease test
Carbon-13 urea breath test (standard test to confirm eradication post treatment)
Fecal antigen test
Indications for antroduodenal motility testing in gastric disease.
Anomalous epigastric symptoms
Transcutaneous recording of gastric myoelectric activity
