Gastroesophageal reflux disease (GERD) is a chronic condition characterized by the reflux of gastric contents into the esophagus. It is a common disorder, affecting approximately 18-28% of the general population in Western countries (Kahrilas et al., 2008). The primary clinical characteristic of GERD is a burning sensation in the chest or throat, commonly referred to as heartburn. Other symptoms include regurgitation, dysphagia, and cough (Eslick et al., 2014).
To diagnose GERD, a combination of clinical evaluation and diagnostic tests is necessary. A thorough medical history and physical examination are essential to assess the patient’s symptoms and determine the presence of risk factors or comorbidities. The frequency and severity of symptoms, as well as their relation to meals and body position, are important considerations in diagnosing GERD (Katzka & Nishioka, 2013).
Various diagnostic tests and screening tools can aid in the diagnosis of GERD. The most commonly used laboratory test is esophageal pH monitoring, which measures the acidity of the esophagus over a 24-hour period (Shaker et al., 2014). This test helps confirm the presence of abnormal acid reflux and assess the correlation between symptoms and acid exposure.
Another useful diagnostic tool is upper gastrointestinal endoscopy, also known as esophagogastroduodenoscopy (EGD). This procedure allows direct visualization of the esophagus, stomach, and duodenum, and helps identify any structural abnormalities, such as esophagitis or hiatal hernia (Kahrilas et al., 2008). Biopsy samples can be taken during EGD to assess the presence of esophageal inflammation or Barrett’s esophagus, a condition associated with an increased risk of esophageal adenocarcinoma.
Imaging studies, such as barium swallow or esophagram, can also be used to evaluate the anatomy and function of the esophagus and identify any structural abnormalities, such as strictures or motility disorders (Johnson et al., 2015). These tests are particularly useful in patients with dysphagia or suspected mechanical obstruction.
In addition to laboratory and imaging tests, there are also non-invasive screening tools available for diagnosing GERD. One such tool is the GERD Questionnaire (GerdQ), a validated self-administered questionnaire that assesses the frequency and severity of typical GERD symptoms (Jones et al., 2009). The GerdQ can be a useful screening tool in primary care settings to identify patients who may require further diagnostic evaluation.
I selected esophageal pH monitoring and upper gastrointestinal endoscopy as appropriate diagnostic tests for GERD because they provide valuable information about both acid exposure and structural abnormalities. Esophageal pH monitoring is considered the gold standard for diagnosing acid reflux and determining its temporal relationship with symptoms (Bredenoord et al., 2018). It allows for a quantitative assessment of acid exposure, which is essential in distinguishing physiological gastroesophageal reflux from pathological acid reflux.
Upper gastrointestinal endoscopy, on the other hand, allows direct visualization of the esophagus and provides valuable information about the presence of inflammation or structural abnormalities. It is particularly useful in patients with refractory GERD symptoms or suspected complications, such as esophageal strictures or Barrett’s esophagus (Shaheen et al., 2016).
The GerdQ questionnaire, on the other hand, is a practical and cost-effective screening tool that can be used in primary care settings. It helps identify patients with a high likelihood of GERD who may require further diagnostic evaluation. The questionnaire can be easily administered and completed by the patient, providing a quick assessment of the frequency and severity of GERD symptoms.
In conclusion, the diagnosis of GERD involves a combination of clinical evaluation and diagnostic tests. Esophageal pH monitoring and upper gastrointestinal endoscopy are appropriate laboratory and imaging tests, respectively, that help assess acid reflux and identify structural abnormalities. Non-invasive screening tools, such as the GerdQ questionnaire, can aid in identifying patients who require further diagnostic evaluation. A comprehensive diagnostic approach is essential to ensure accurate diagnosis and appropriate management of GERD.
