Gastrointestinal Tests & Screenings

Detecting the source of your digestive disorder is one of the first steps in proper treatment. At West Suburban Medical Center, we offer a wide range of tests and screenings. See below for common diagnostic tests and screenings.

Bravo probe

This type of test lasts for two days and is performed on the esophagus. Ph levels are measured in the esophagus by attaching a small capsule to the esophagus during an endoscopy; this test is used to diagnose reflux.


Using an instrument called a colonoscope (a tiny camera attached to a long, thin tube), doctors can look inside your entire large intestine for things such as inflamed tissue, abnormal growths, and ulcers.


ERCP is Endoscopic Retrograde Cholangiopancreatography. This technique combines endoscopy and fluoroscopy to diagnose and treat certain conditions of the liver and pancreas.

Esohagastroduodenoscopy (EGD)

EGD is a test to examine the lining of the esophagus, stomach and first part of the small intestine using an endoscope, a flexible tube with a camera at the end.

Flexible Sigmoidoscopy

This procedure uses a flexible, narrow tube with a tiny camera on one end, called a sigmoidoscope, to look inside the rectum and the lower, or sigmoid, colon. Flexible sigmoidoscopy can show irritated or swollen tissue, ulcers and polyps.

PEG Placement

Percutaneous endoscopic gastrostomy (PEG) is a procedure in which a flexible tube is passed through the abdominal wall and into the stomach to allow for nutrition, fluids and/or medications to be put directly into the stomach, bypassing the mouth and esophagus.

Push Enteroscopy

A thin, flexible tube (endoscope) is inserted through the mouth and into the upper gastrointestinal tract.

Small bowel capsule endoscopy

The procedure is an examination of the middle portion of your digestive tract —- including the small intestine. A small, pill-sized capsule (that contains a camera) is given to a patient to swallow, doctors are then able to view pictures of the small intestine as the camera makes its way through the body.
