Upper Endoscopy (EGD)
Upper endoscopy, also called esophagogastroduodenoscopy (EGD), is a widely used diagnostic procedure that allows a gastroenterologist to examine the esophagus, stomach, and upper portion of the small intestine. At North Shore Gastroenterology, our board certified GI specialists perform EGD in Westlake and Brooklyn, OH, to evaluate symptoms such as heartburn, difficulty swallowing, upper abdominal pain, chronic nausea, or unexplained bleeding. Using high-definition imaging and minimally invasive instruments, an upper endoscopy helps diagnose digestive conditions early, guide treatment, and support long-term gastrointestinal health.
Conditions Diagnosed by Upper Endoscopy
Upper endoscopy provides direct visualization of the upper gastrointestinal tract and is used to diagnose a range of conditions. These include acid reflux disease (GERD), esophagitis, gastritis, Barrett’s esophagus, peptic ulcers, celiac disease, and structural abnormalities such as strictures or hiatal hernias. EGD can also evaluate unexplained anemia, persistent upper abdominal pain, or difficulty swallowing. By examining the lining of the esophagus, stomach, and duodenum, the procedure helps identify inflammation, bleeding, infection, or precancerous tissue that may require treatment or monitoring.
Why Upper Endoscopy Is Performed?
Your gastroenterologist may recommend upper endoscopy to investigate symptoms that cannot be fully explained through laboratory testing or imaging alone. EGD allows for evaluation of chronic heartburn, regurgitation, indigestion, early satiety, or suspected ulcer disease. It is also used to diagnose swallowing disorders, assess esophageal injury related to long-term reflux, and evaluate conditions such as Barrett’s esophagus. If needed, biopsies can be taken during the procedure to test for Helicobacter pylori, celiac disease, or abnormal tissue changes. Upper endoscopy is also used to treat certain conditions, including esophageal narrowing or active bleeding.
About the Procedure
During an upper endoscopy, you will receive sedation to keep you relaxed and comfortable. Once sedated, you will lie on your left side as the physician gently inserts a thin, flexible tube with a light and camera (endoscope) through your mouth and advances it into the esophagus, stomach, and upper small intestine. A small amount of air is introduced to expand the digestive tract and improve visibility. The endoscope transmits high-resolution images to a monitor, allowing the physician to examine the lining for inflammation, ulcers, bleeding, or other abnormalities.
If necessary, instruments can be passed through the scope to obtain biopsies, remove small growths, or treat bleeding. The procedure typically takes 15 to 30 minutes, though patients should plan to remain at the facility for additional time to allow for preparation and recovery.
Because sedation is used, a responsible adult must drive you home afterward. Most patients return to normal activities the following day.
Preparation and Recovery
To ensure accurate results, patients are instructed not to eat or drink for several hours before the procedure. Your care team will review medications and provide specific instructions, especially if you take blood thinners or diabetes medications. After the procedure, mild throat soreness or bloating may occur temporarily. Biopsy results, if taken, are typically available within several days. Your gastroenterologist will discuss findings and next steps during a follow-up visit or phone call.
