    What If Heartburn or GERD Symptoms Persist? continued...

    An upper GI series may be performed during the early phase of testing. This test is a special X-ray that shows the esophagus, stomach, and duodenum (the upper part of the small intestine). While an upper GI series provides limited information about possible reflux, it is used to help rule out other diagnoses, such as peptic ulcers.

    Endoscopy is an important procedure for individuals with chronic GERD. By placing a small lighted tube with a tiny video camera on the end (endoscope) into the esophagus, the doctor may see inflammation or irritation of the tissue lining the esophagus (esophagitis). If the findings of the endoscopy are abnormal or questionable, biopsy (removing a small sample of tissue) from the lining of the esophagus may be helpful.

    Esophageal manometric and impedance studies -- pressure measurements of the esophagus -- occasionally help identify low pressure in the LES or abnormalities in esophageal muscle contraction.

    For patients in whom diagnosis is difficult, doctors may measure the acid levels inside the esophagus through pH testing. Testing pH monitors the acidity level of the esophagus and symptoms during meals, activity, and sleep. Newer techniques of long-term pH monitoring are improving diagnostic capability in this area.

    Does GERD Require Surgery?

    A small number of people with GERD may need surgery because of severe reflux and poor response to medical treatment. However, surgery should not be considered until all other measures have been tried. Fundoplication is a surgical procedure that increases pressure in the lower esophagus. Endoscopic procedures that involve making the LES function better or using electrodes to promote scarring of the LES are newer options in treatment.

    What Are the Complications of Long-Term GERD?

    Sometimes GERD results in serious complications. Esophagitis can occur as a result of too much stomach acid in the esophagus. Esophagitis may cause esophageal bleeding or ulcers. In addition, a narrowing or stricture of the esophagus may occur from chronic scarring. Some people develop a condition known as Barrett's esophagus. This condition can increase the risk of esophageal cancer.
