Gastroduodenoscopy

Gastroduodenoscopy refers to an examination of the inner surface of the stomach and the initial portion of the small intestine (duodenum) using a flexible, fiberoptic endoscope. In addition to visual inspection, gastroduodenoscopy provides the ability to obtain multiple biopsies from the lining of the small intestine and stomach. Gastroduodenoscopy, therefore, provides an excellent tool in the diagnosis of multiple disorders of the intestinal system. Although general anesthesia is required, gastroduodenoscopy is generally a safe, non-surgical, non-painful procedure. Most patients are discharged the same day that the procedure is performed.

The major symptoms and reasons to perform a gastroduodenoscopy are:

  • Persistent vomiting
  • Persistent weight loss due to a small bowel disorder
  • Black, tarry stools (persistent melena)
  • Chronic diarrhea due to a small intestine disorder
  • Vomiting blood
  • Possible stomach or intestinal blockage
  • Inability to chew or swallow normally (dysphagia)
  • Removal of foreign matter from the stomach or esophagus
  • Placement of a feeding tube
