Diagnostic Tests 

 If you’re experiencing heartburn, abdominal pain, recurrent indigestion or other uncomfortable gastrointestinal (GI) symptoms, Baylor Scott & White - Plano has the diagnostic expertise to pinpoint your problem. We use a variety of endoscopic and imaging tests to diagnose conditions of the esophagus, stomach, small bowel, colon and gallbladder. These include:


Starting at age 50, men and women should have a colonoscopy every 10 years. During this test, a colonoscope, which has a small camera on the end of a flexible tube, is used to examine the entire colon. A colonoscopy can identify precancerous polyps in the colon—polyps that can be removed during the procedure to prevent colon cancer from ever developing.

Spyglass® Direct Visualization System

Using a tiny fiber-optic camera, this advanced technology gives physicians the ability to literally look inside something as tiny as a bile duct, aiding in the diagnosis of conditions such as gallstones, suspected cancers, obstructions and cystic lesions. The system also has a miniature forceps, allowing it to collect tissue samples for biopsy as it’s taking images.

ERCP (endoscopic retrograde cholangiopancreatography)

An endoscope, which is a tiny tubular instrument, is inserted through the mouth and into the duodenum (the part of the small intestine that is closest to the stomach) to allow physicians to identify stones, tumors, or narrowing in the bile ducts.

Liver biopsy

By taking a small section of the liver, physicians can test the sample for cancer, infections and other causes of abnormal liver function.

Esophageal motility study

This test measures the pressure inside the lower part of your esophagus, which can help doctors diagnose swallowing problems that may be contributing to gastroesophageal reflux disease (GERD).

Esophageal pH study

In this test, a thin tube is passed through your nose and into your esophagus. The other end is attached to a monitor that measures over a 24-hour period how often and for how long stomach acid enters the tube. The test helps physicians diagnose and treat gastroesophageal reflux disease (GERD).

Upper GI endoscopy (EGD)

Also known by the long name of esophagogastroduodenoscopy, this test uses a smaller camera (endoscope) to examine the lining of the esophagus, stomach and upper duodenum to help diagnose abdominal pain, upper GI bleeding and other GI problems.

Small bowel capsule endoscopy

The PillCam is a technology that lets physicians diagnose problems in the small bowel. Small-bowel capsule technology is helpful because endoscopies are unable to reach this part of the body. During this test, a person swallows a small capsule about the size of a vitamin that contains a camera. As the pill travels through the body, it transmits pictures to let a doctor see what’s happening.
