Symptoms of GERD can be confusing. So using proper diagnostic tools is rather important correctly diagnosing GERD. Here are the three questions we try to find answers for when you come to us for GERD treatment. The course of the treatment is decided based on what the investigation shows.

1. Does the patient have GERD?

The commonest diagnostic test carried out to ascertain presence of GERD is upper GI endoscopy, wherein we insert a video camera into the esophagus and look for erosion and ulcers caused by the acid attack. This test is accurate in about 7 out of 10 cases.

Whereas, 3 out of 10 GERD patients have normal looking inner lining. This condition is called ENRD (Endoscopy Negative Reflux Disease) or NERD (Non-Erosive Reflux Disease). Therefore, if you have symptoms of GERD, don’t ignore them just because your endoscopy is normal.

Go to our page on upper GI endoscopy for a detailed description of how this diagnostic exercise is carried out.

2. How much acid really goes across the valve?

To answer this question, the most efficient single tool is the 24 hours ambulatory pH study (ambulatory = adapted to walking around with).   In this test, we pass special thin tubes through the nose to sit in the gullet and the stomach. Electronics attached to the other end of the tubes record the amount of acid that goes back across the valve <more details please>.

While the endoscopy is a quality tool, the 24 hour pH study is a quantitative tool that permits us to quantify the amount of reflux across the lower esophageal sphincter.

As per the international quantification <reference needed>, total time length of reflux over a 24 hour period classifies the disease as under:

  • <4% is normal
  • 4% ~ 8% is considered a mild disease
  • 8% to 20% is considered a moderate disease
  • >20% is considered a severe disease.

Go to our page on 24 hour pH study for a details discussion on this diagnostic tool.

3. How is a Treatment Option Selected?

Before we operate on a patient, we study the esophagus through a manometry. A manometry shows how efficiently the patient is able to move the food along the food pipe. If the manometry shows that the patient has a weak esophagus, we fine tune the surgery so that the patient will not have swallowing difficulty post-operatively.

Go to our page on manometry for a detailed discussion on this diagnostic tool.

Unless the patient has an unusual condition, no other diagnostic tools for fundoplication is considered relevant.
