Gastroesophageal Reflux Disease (GERD) - Examination and Diagnostic Procedures

Gastroesophageal Reflux Disease (GERD) - Examination and Diagnostic Procedures

Gastroesophageal Reflux Disease (GERD) is a common condition that affects many individuals worldwide. In this article, we will explore the main diagnostic tests and treatments for GERD.

Diagnostic Tests

The most common diagnostic tests for GERD are upper endoscopy (esophagogastroduodenoscopy), esophageal manometry, 24-hour pH monitoring (including impedance monitoring), and barium swallow studies. These tests assess the structure and function of the esophagus and measure acid reflux episodes in different ways.

Upper Endoscopy (EGD)

An endoscope (a flexible tube with a camera) is inserted through the mouth to visually examine the esophagus, stomach, and upper small intestine. It can detect esophageal inflammation (esophagitis), ulcers, strictures, or Barrett’s esophagus. Advanced AI models are now being used to analyze endoscopic images for grading GERD severity with high accuracy based on the Los Angeles (LA) classification and gastroesophageal flap valve grading, improving diagnostic precision.

Esophageal Manometry

This test measures the rhythmic muscle contractions (motility) of the esophagus and the function of the lower esophageal sphincter (LES). A thin tube with pressure sensors is passed through the nose into the esophagus. It helps evaluate whether the LES is functioning properly to prevent reflux and can identify motility disorders that might mimic GERD symptoms.

24-hour pH Monitoring and pH Impedance Monitoring

A probe is placed in the esophagus to measure acid exposure over 24 hours. The traditional pH monitoring detects acid reflux episodes by measuring pH changes below 4. Impedance monitoring also detects reflux of non-acidic fluids by measuring changes in electrical resistance, providing a more comprehensive assessment of all types of reflux events. These tests correlate symptoms with acid or non-acid reflux episodes to confirm GERD diagnosis.

Barium Swallow Study

The patient swallows a contrast material (barium) and X-rays track its movement down the esophagus, helping to identify structural abnormalities like hiatal hernias, strictures, or delayed esophageal emptying that could contribute to reflux symptoms.

Additional tests like carbohydrate malabsorption breath tests, gastric emptying studies, and small intestinal bacterial overgrowth (SIBO) breath tests may be used to identify related digestive problems or rule out other causes of symptoms.

Treatment

Without treatment, GERD can cause Barrett's esophagus, a condition where different tissue similar to that which lines the intestine replaces the usual lining of the esophagus.

People generally tolerate GERD treatments well, and the condition responds well to habit changes and medications. Treatment may be long-term. The esophageal manometry test measures the motion of muscles that control the digestive system and how well food passes through it.

Treatment for GERD includes medications such as antacids, H2 blockers, and proton pump inhibitors (PPIs). Bariatric surgery may be recommended for individuals who are overweight to help manage GERD. Surgery may be recommended for GERD when habit changes and medication have proved unsuccessful.

In summary, these tests combine to evaluate anatomical changes, esophageal motility, and the presence and timing of acid and non-acid reflux episodes to establish the diagnosis of GERD and guide treatment decisions. Emerging AI-enhanced endoscopy techniques are improving accuracy in detecting esophagitis and grading GERD severity.
