Upper Endoscopy (EGD)

Precision through Endoscopy

An endoscopy, or esophogastroduodenoscopy (EGD), is a specialized procedure that provides high-quality images of the esophagus, stomach and duodenum to aid in diagnosing problems of the upper digestive system. An upper GI endoscopy can be more precise than an X-ray in evaluating problems such as difficult or painful swallowing, pain in the stomach or abdomen, gastrointestinal bleeding, ulcers and tumors.

Dr. Arora is trained in the use of endoscopy to:

  • Biopsy: A specimen of tissue is removed for examination by a pathologist
  • Remove polyps: An abnormal growth is removed
  • Perform a balloon or bougie (instrument) dilation: A balloon is inflated or a bougie is passed to dilate or open a narrowed portion of the esophagus
  • Control bleeding: Medication or heat is administered to stop bleeding

When is a Capsule Endoscopy Performed?

A capsule endoscopy can help us examine the lining of the middle part of your gastrointestinal tract. For the procedure, you will be given a pill-sized video camera to swallow. This camera has its own light source and takes pictures of your small intestine as it passes through. These pictures are sent to a small recording device you may wear on your body.

Capsule endoscopy is useful in evaluating the small intestine. This part of the bowel cannot be reached by traditional upper endoscopy or by colonoscopy. The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, inflammatory bowel disease (Crohn’s disease), ulcers and tumors of the small intestine.

When is a Small Bowel Endoscopy Useful?

The small bowel is approximately 20 feet in length and, until recently, was a relatively inaccessible part of the gastrointestinal tract. Small bowel endoscopy, or balloon-assisted enteroscopy, now offers advanced, non-surgical small bowel diagnoses and therapy. Through this relatively new technique, we can biopsy tissue, dilate strictures, remove polyps and stop bleeding from the small bowel. In some instances, therapy with a balloon-assisted scope may allow a patient to avoid surgical intervention on the small bowel.

The single-balloon system used by Dr. Arora consists of an endoscope and an overtube with a balloon attached. The technique allows the scope to advance through the length of the small bowel via the process of inflating and deflating the balloon, which grips the walls of the small intestine. With a series of reductions, the process pleats the small bowel over the overtube, like a curtain over a rod, and advances the scope for viewing.
