Indications for Gastroscopy

Indications for Gastroscopy

Gastroscopy is indicated in patients with abdominal pain, internal bleeding, or for the dilatation of esophageal strictures.

Indications for doing gastroscopy include -

  • Acute upper gastrointestinal bleeding, to establish the exact location of bleed prior to endoscopic cautery, surgery, etc.
  • Dysphagia or difficulty with swallowing, especially if esophageal strictures or ulcerations are seen on a previous upper gastro intestinal series.
  • Dyspepsia (indigestion) or heartburn, if refractory to standard medications. It is also indicated whenever a surgical procedure is planned in the upper digestive tract.
  • Odynophagia or difficulty swallowing, when inflammation or infection is clinically suspected, especially if infection of the food pipe from candida, cytomegalovirus, or herpes simplex virus is likely.
  • Surveillance endoscopy for known pre-malignant conditions affecting the upper digestive tract, such as Barrett's esophagus, lye-induced strictures (tight areas brought about by ingestion of a certain detergent) or Plummer-Vinson syndrome.
  • Abnormalities seen on with other tests which require visual confirmation and tissue biopsy (eg: polyps, gastric ulcers, redundant gastric folds, strictures).
  • Suspected obstruction at the end of the stomach.

Indications for Doing Gastroscopy

Treatments that can be done during the gastroscopy procedure include -

  • Sclerotherapy of bleeding esophageal varices (open blood vessels at the base of the food pipe)
  • Management of upper GI bleeding using electrocautery, photocoagulation, etc
  • Laser ablation of esophageal cancer
  • Endoscopic placement of esophageal stents to correct any narrowing
  • Placement of permanent feeding tubes under endoscopic guidance (PEG tubes)
  • Dilatation of esophageal strictures
  • Polypectomy or removal of benign growths called polyps
  • Dissolution of bezoars – A bezoar is a mass of indigestible material present in the digestive tract
