Minimally Invasive Diagnostic Test Helps Determine Cause of Symptoms

If you are one of the millions of Americans who suffer from acid reflux, also known as gastroesophageal reflux disease (GERD), you know how painful it can be. Heartburn is the most common symptom, but others can include belching, sore or burning throat from regurgitation of stomach acid, hoarseness and chest pain.

Gastroenterologist M. Mazen Jamal, MD, says a new minimally invasive way to evaluate chronic heartburn symptoms is now available. “A small capsule-shaped device is attached to the esophagus wall for 48 hours. It measures the pH in the esophageal environment and sends the information wirelessly to a recorder worn on the patient’s belt or waist, much like a cell phone.”  

Following the testing period, the patient returns the recorder to the doctor’s office so the data can be downloaded and analyzed. The capsule detaches from the esophagus wall on its own and is passed through the digestive tract. This method of testing does not interfere with the patient’s daily activities or meals, yet provides valuable information on acid reflux and the frequency of the symptoms.

GERD occurs when the one-way valve between the esophagus and stomach loosens and stops functioning properly, allowing stomach contents back into the esophagus. “Over time, GERD can damage the esophagus lining, which can lead to esophageal cancer,” says Dr. Jamal. “With these test results, we can determine the appropriate treatment for the patient, whether it be medication, lifestyle changes or minimally invasive surgical options.”
