Upper GI Endoscopy

An Upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a special exam of your upper gastrointestinal (GI) tract. This exam allows your doctor to look at the upper gastrointestinal tract, including the esophagus (throat), stomach, and the duodenal (upper) portion of the small intestine. This exam may be performed when you have symptoms such as heart burn, difficulty swallowing, painful swallowing, bleeding or other upper GI symptoms. This exam can diagnose ulcers, gastritis, tumors and causes of bleeding or pain. It may also be used to take biopsies, remove foreign objects (food) or polyps, stop bleeding, and open strictures (narrow areas). 

Esophageal pH Test

Spencer Hospital has the Medtronic Bravo System and AccuView pH-Z software to provide this enhanced diagnostic capability.

An esophageal pH test measures and records the pH in your esophagus to determine if you have gastroesophageal reflux disease (GERD). The test can also be done to determine the effectiveness of medications or surgical treatment for GERD.

For the test, a surgeon will place a miniature pH capsule to your esophagus during a routine endoscopy procedure.

Throughout the test period, the Bravo capsule measures the pH in the esophagus and transmits this information to a pager-sized receiver worn on your belt or waistband just like a pager or mobile phone. When you have reflux symptoms (for example, coughing, heartburn, regurgitation), when eating or when lying down, you will be able to record those into the device. At the same time, the capsule will transmit data to the recorder regarding the acid levels in your esophagus.

After the test is completed, you return the diary and the Bravo Receiver to your doctor and the information is uploaded to a computer, which provides a comprehensive report so the physician can diagnosis your condition.


A colonoscopy is a special exam of your colon or lower gastrointestinal tract. This exam allows your doctor to look at the inside walls of your colon for abnormalities. This exam may be performed when you have symptoms of persistent diarrhea, blood in the stools, other unexplained intestinal symptoms or for screening for polyps or colon cancer.
