24 hour pH Impedance Study in Ahmedabad

24 hour pH Impedance Study in Ahmedabad

The esophageal pH test is an outpatient procedure that measures the pH or amount of acid that flows into the oesophagus from the stomach over the course of 24 hours. Esophageal manometry is always included in a 24-hour pH study.

24 hour pH Impedance Study may help in :

  • Study of symptomatic patients, endoscopically controlled, with negative exam (NERD)
  • Study of patients endoscopically controlled with therapyresistant symptoms
  • Study of patients with atypical or extra-esophageal symptoms (such as pharyngitis, rhinitis, cough, asthma, retrosternal pain, etc..)
  • Study of patients in which surgical treatment for gastroesophageal reflux disease is indicated.

Why 24 hour pH Impedance Study Used ?

The 24 hour pH impedance study is a diagnostic test used to evaluate and diagnose gastroesophageal reflux disease (GERD) and other disorders related to esophageal function. It measures the movement of acid and other stomach contents from the stomach into the esophagus and how long they stay there.
Some of the common reasons why a 24 hour pH impedance study may be used include :

  1. Persistent symptoms of GERD despite treatment with medications
  2. Evaluation of symptoms such as heartburn, regurgitation, chest pain, and difficulty swallowing
  3. Assessment of the effectiveness of GERD treatments such as medications or surgery
  4. Detection of reflux events in patients with respiratory or voice symptoms
  5. Assessment of the function of the lower esophageal sphincter and esophageal muscles

During the test, a thin, flexible tube is inserted through the nose and passed down the esophagus into the stomach. The tube contains sensors that measure the pH level and impedance of the contents in the esophagus. Patients are required to wear the tube for 24 hours and record their symptoms and activities during that time. The data collected from the test is then analyzed to determine the frequency and duration of acid reflux events, as well as the correlation between reflux events and symptoms.

24 hour pH impedance study is a valuable tool for diagnosing and managing GERD and other esophageal disorders, allowing for tailored treatment plans to be developed based on the individual patient's needs.

Types of 24 hour pH impedance study procedure

There are two main types of 24 hour pH impedance study procedure :

24 hour pH impedance study
  • Catheter-based pH Impedance Monitoring : In this procedure, a thin tube called a catheter is inserted through the nose and positioned in the lower esophagus. The catheter is left in place for 24 hours, during which time it measures the pH level of the esophagus and detects the presence of any reflux events.
  • Wireless pH Impedance Monitoring : This procedure involves swallowing a small, wireless capsule that contains a pH and impedance sensor. The capsule is passed through the digestive tract and records pH and impedance measurements as it moves through the esophagus, stomach, and small intestine. The data is transmitted to a receiver worn on a belt or waistband.

Both types of pH impedance monitoring provide valuable information about the frequency, duration, and type of reflux events, as well as the location of the reflux within the esophagus. This information can help doctors diagnose and treat conditions such as gastroesophageal reflux disease (GERD), non-cardiac chest pain, and other esophageal disorders.

Benefits of 24 hour pH impedance study

The benefits of 24 hour pH impedance study include :

  1. Accurate diagnosis : 24 hour pH impedance study helps in accurate diagnosis of acid reflux and related disorders. It can help differentiate between acid reflux and non-acid reflux, which can guide appropriate treatment.
  2. Better treatment : With accurate diagnosis, treatment can be customized to suit the patient's needs. This can result in better treatment outcomes, including improved symptom relief and quality of life.
  3. Minimally invasive : The 24 hour pH impedance study is a minimally invasive procedure that is safe and well-tolerated by patients. It involves placing a small catheter through the nose and into the esophagus, which does not cause significant discomfort.
  4. Helps monitor treatment : 24 hour pH impedance study can also be used to monitor the effectiveness of treatment over time. By tracking the amount of acid reflux and symptom severity, doctors can adjust treatment plans as needed to achieve the best possible outcomes.
  5. Prevent complications : By accurately diagnosing acid reflux and related disorders, 24 hour pH impedance study can help prevent complications such as esophageal strictures, Barrett's esophagus, and esophageal cancer.

Case Study

Successful 24-Hour pH Impedance Study in a 28-Year-Old Male Patient

Patient Information :28-year-old male who presented to our clinic with complaints of heartburn and regurgitation. He reported experiencing these symptoms almost every day, despite taking over-the-counter antacids. He had no significant medical history and was not taking any medications.

Conclusion : This case demonstrates the successful use of a 24-hour pH impedance study in diagnosing GERD in a 28-year-old male patient with heartburn and regurgitation. 24-hour pH impedance study is a safe and minimally invasive procedure for evaluating acid reflux and can help guide appropriate treatment strategies. With experienced endoscopic technique, a 24-hour pH impedance study can provide valuable information to manage patients with GERD.

What Our Patients Say About Our Medical Treatments


Frequently Asked Questions (FAQ)

1. Are there any risks associated with a 24-Hour pH Impedance Study?
Like any medical procedure, there are some risks associated with a 24-Hour pH Impedance Study, such as irritation or injury to the nasal passages or throat. However, these risks are relatively low, and the benefits of the test usually outweigh the risks.
2. How accurate is a 24-Hour pH Impedance Study?
This test is highly accurate in diagnosing reflux disorders such as GERD and LPR, as it measures the amount of acid and other fluids that flow back up from the stomach into the esophagus over a 24-hour period.
3. What should I expect after the 24-Hour pH Impedance Study?
After the test is completed, the patient returns to the doctor's office to have the tube removed. Some patients may experience mild discomfort or irritation in the nose or throat after the test.
