Gastroesophageal Reflux Study in Chennai
The Gastroesophageal Reflux (GER) study, also known as an Esophageal Transit Study or Gastroesophageal Reflux Scintigraphy, is a nuclear medicine imaging procedure used to evaluate the presence and severity of gastroesophageal reflux disease (GERD) and assess esophageal motility.
What is the need for the study?
The GER study is performed to:
- Determine the extent and frequency of gastroesophageal reflux, where stomach contents flow back up into the esophagus.
- Assess the effectiveness of medical or surgical treatments for GERD.
- Identify underlying esophageal motility disorders that may contribute to GERD symptoms.
This study helps healthcare providers diagnose GERD accurately and develop appropriate treatment plans to manage symptoms and prevent complications.
How do I prepare?
Preparation for a GER study may include:
- Medication: Inform your healthcare provider about any medications you are taking, as certain medications may need to be temporarily stopped before the study.
- Fasting: You may be instructed to fast for a period before the study, typically for several hours, to ensure an empty stomach for accurate imaging.
- Clothing: Wear comfortable clothing and avoid wearing any metallic objects or jewellery that may interfere with the imaging process.
- Medical History: Provide your healthcare provider with a detailed medical history, including any previous gastrointestinal conditions or surgeries.
Your healthcare provider will provide specific instructions on how to prepare for the GER study based on your individual circumstances.
How is this scan performed?
During a GER study:
- Radiotracer Ingestion: You will ingest a small amount of a radioactive tracer, typically technetium-99m (Tc-99m), mixed with water or a meal. The tracer is harmless and helps visualize the movement of food and fluid through the digestive system.
- Imaging: A gamma camera is used to capture images of the esophagus and stomach as the tracer moves through the gastrointestinal tract. Dynamic images may be acquired to monitor reflux episodes and assess esophageal motility.
- Monitoring: You may be asked to lie down or sit upright during the scan to simulate normal eating and digestion conditions. The imaging process typically takes about 1 to 2 hours.
What should I do after the scan?
After the GER study:
- Resume Normal Activities: You can usually resume your normal activities immediately after the scan.
- Follow-Up: Attend any scheduled follow-up appointments with your healthcare provider to review the results of the study and discuss further management, if necessary.
Are there any risks in the study?
The GER study is generally considered safe and non-invasive. The amount of radiation exposure from the radioactive tracer used in the study is minimal and poses little risk to most patients. However, as with any medical procedure involving radiation, there is a small risk of allergic reactions or adverse effects.
Your healthcare provider will discuss the potential risks and benefits of the GER study with you and address any concerns you may have before proceeding with the procedure.
It’s essential to follow all instructions provided by your healthcare provider and communicate any symptoms or concerns you experience during or after the GER study. Your healthcare team is here to support you throughout the process and ensure the best possible outcomes for your gastrointestinal health.
