At GRMC, we offer state-of-the-art Endoscopy equipment and take pride in the care and safety provided to each patient. Endoscopy is a non-surgical procedure, that can be performed in either an inpatient or outpatient setting, used to examine a patient's digestive tract. By using a small camera on the end of a long flexible tube, a physician can view your digestive tract to diagnose and sometimes treat conditions that do not always appear on other imaging tests.

Upper GI endoscopies, EGD’s, focus on your esophagus, stomach, and upper small bowel. While lower GI endoscopies enables the physician to see ulcers, lining of the intestine, abnormal growths (polyps), bleeding in the colon, or large bowel. Both endoscopies and colonoscopies are performed at GRMC to examine, diagnose and treat conditions of gastroenterological conditions.

The Endoscopy team includes Nurse Anesthetists (CRNA), Anesthesiologists, and Registered Nurses (RN). Each Endoscopy tech is a Licensed Vocational Nurse, who is certified in Flexible Endoscope Reprocessing (CFER) and carry over 35 years of combined experience.
