Focused on relief & resolution, not procedures.

A complex system, the gastrointestinal tract can be affected by a number of disorders. And they are often subtle and difficult to understand. So we focus not on a particular procedure or treatment but on understanding and resolving your unique problem. This starts by listening to you carefully and investigating things thoroughly. And we look for the options that are best for you, not for us. Because one-of-a-kind problems don’t benefit from one-size-fits-all care. Below are some of the routine procedures that we do at Gastrointestinal Associated Specialists in North Kansas City, Missouri:

The doctor uses a lighted tube to look inside the length of your colon, looking for any growth that could be cancer or a polyp that could turn into cancer. If he sees something that concerns him, he can take a biopsy immediately and test it for cancer.

Upper Endoscopy/Esophagogastroduodenoscopy (EGD)
Upper GI endoscopy, sometimes called EGD (esophagogastroduodenoscopy), is a visual examination of the upper intestinal tract using a lighted, flexible fiberoptic or video endoscope, which is usually performed on an outpatient basis.

Capsule Endoscopy - Pill Cam
Capsule Endoscopy enables the doctor to examine your entire small intestine by swallowing a small camera contained within a capsule.

BravoTM pH Test
The Bravo pH capsule (about the size of a gelcap) is used to measure the pH levels in the esophagus over a 48 hour period, which helps in diagnosing gastro-esophageal reflux (GERD).

24-hour Esophageal pH Study
An esophageal 24-hour pH test measures how often stomach acid or non-acid fluid flows into the lower esophagus and the degree of acidity during a 12-24 hour period.

Esophageal (pH) Manometry
The esophageal manometry test measures the motor action of the muscles that are in the upper and lower ends of the esophagus, as well as the motor function of the esophageal body.

Flexible Sigmoidoscopy
Flexible Sigmoidoscopy lets your doctor examine the lining of the rectum and a portion of the colon (large intestine).

Biological Infusion Therapy
Remicade is a medication used for patients with Crohn’s disease and rheumatoid arthritis. Our office provides a quiet and peaceful setting to receive this infusion.

The team to trust for chronic, long-term and unknown GI problems.

Many people with GI problems can go months or years without a solution… or a diagnosis or even the right questions. But their problems are real, though they are too often left without options, guidance or results. We take pride in giving these patients the extra time, effort and dedication their problems demand. And we emphasize patient education, because simply understanding your problem and how to cope with it can be a huge step toward relief.
