78262 Gastroesophageal reflux study

Name of the Procedure:

Gastroesophageal Reflux Study

Summary

A Gastroesophageal Reflux Study is a diagnostic procedure that measures the acid levels and activity in the esophagus to determine if gastrointestinal reflux disease (GERD) is present. This test involves placing a probe in the esophagus to monitor acid content over a 24-hour period.

Purpose

The procedure is designed to diagnose GERD, a condition where stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus). The goal is to confirm the presence of acid reflux, assess its severity, and determine the effectiveness of current treatments.

Indications

• Persistent heartburn
• Regurgitation of food or sour liquid
• Difficulty swallowing
• Chest pain, especially while lying down or after eating
• Chronic cough or hoarseness

Preparation

• Fast for 6-8 hours before the procedure.
• Avoid certain medications that can affect acid levels, as instructed by your doctor.
• Wear loose, comfortable clothing.
• Complete any preliminary diagnostic tests as recommended, such as an endoscopy.

Procedure Description

1. A thin, flexible probe is inserted through the nose and positioned in the esophagus.
2. The probe is connected to a small device worn around the waist or over the shoulder.
3. Over a 24-hour period, the probe records the acid levels while the patient goes about their daily activities.
4. The patient is often asked to log symptoms, activities, and meals during the monitoring period.
5. After 24 hours, the probe is removed and the data is analyzed.

Duration

Typically, the entire monitoring period lasts about 24 hours.

Setting

The procedure is performed in an outpatient clinic or a specialized diagnostic center.

Personnel

• A gastroenterologist or trained technician inserts the probe.
• Nursing staff may assist with patient preparation and monitoring.
• A medical specialist will analyze the test results.

Risks and Complications

• Mild discomfort or gagging when the probe is inserted.
• Nasal or throat irritation.
• Rarely, bleeding or infection at the site of probe insertion.

Benefits

• Accurate diagnosis of GERD and its severity.
• Tailored treatment plans based on precise data.
• Potential avoidance of unnecessary treatments.

Recovery

• The procedure itself does not require recovery time.
• Patients resume normal activities immediately after the probe is inserted.
• Follow-up appointment to discuss results and treatment options.

Alternatives

• Esophageal manometry (measures the rhythmic muscle contractions in your esophagus and how well your esophagus works).
• Endoscopy (direct visual examination).
• Empirical treatment trials with medications (without specific diagnosis).
• Pros and cons of each alternative should be discussed with your healthcare provider.

Patient Experience

• Patients may feel slight discomfort or a sensation of pressure during probe insertion.
• The probe may cause a minor sensation of a lump in the throat.
• Daily activities can typically continue as normal.
• Pain management strategies are seldom needed, but mild discomfort can be eased with lozenges or numbing agents if required.
