How Is Modified Prague Maneuver Done?

By Robert Palmer

The Modified Prague Maneuver is a technique used in the treatment of esophageal disorders, such as achalasia and other motility disorders. It involves stretching the lower esophageal sphincter (LES) to improve its function and alleviate symptoms like difficulty swallowing and regurgitation.

Why is the Modified Prague Maneuver performed?

Achalasia is a condition characterized by the inability of the LES to relax properly, causing food and liquids to accumulate in the esophagus. This can lead to symptoms such as chest pain, heartburn, and regurgitation. The Modified Prague Maneuver aims to improve LES function by stretching the muscles and reducing resistance, allowing for better passage of food and liquids into the stomach.

Procedure

The Modified Prague Maneuver is typically performed during an upper endoscopy procedure under sedation. Here’s a step-by-step guide on how it’s done:

  1. Sedation: The patient is given medication to induce relaxation and prevent discomfort during the procedure.
  2. Endoscope insertion: A thin tube with a light and camera on the end (endoscope) is inserted through the mouth into the esophagus.
  3. Visualization: The doctor carefully guides the endoscope towards the LES area while monitoring its progress on a screen.
  4. Balloon insertion: Once near the LES, a deflated balloon catheter is passed through the working channel of the endoscope until it reaches the Targeted area.
  5. Inflation: The balloon is then inflated with water or air, exerting pressure on the LES. This helps stretch and dilate it, improving its function.
  6. Monitoring and deflation: The doctor closely monitors the pressure and duration of the balloon inflation. After a specified period, the balloon is deflated, and the endoscope is slowly withdrawn.

Recovery and Follow-up

Following the Modified Prague Maneuver, patients are usually observed for a short time to ensure there are no immediate complications. They may experience some discomfort or soreness in the throat, but this typically resolves within a few days.

It’s important to follow any post-procedure instructions provided by your healthcare provider. This may include dietary modifications or medications to help manage symptoms during the healing process.

When to Seek Medical Attention

If you experience severe pain, fever, difficulty breathing, excessive bleeding, or any other concerning symptoms after undergoing the Modified Prague Maneuver, it’s crucial to seek immediate medical attention. These symptoms could indicate complications that require prompt evaluation and treatment.

Potential Risks and Complications

While the Modified Prague Maneuver is generally considered safe, there are certain risks involved:

  • Bleeding: In rare cases, balloon inflation can cause minor bleeding at the treatment site.
  • Tear or perforation: There’s a small risk of unintentional tearing or puncturing of the esophageal wall during the procedure.
  • Infection: Although rare, there’s a minimal risk of developing an infection at the treatment site.
  • Allergic reactions: Some patients may have an allergic reaction to sedation medications used during the procedure.

Your healthcare provider will discuss these risks and potential complications with you before the procedure to ensure you are fully informed.

Conclusion

The Modified Prague Maneuver is a valuable technique in the management of esophageal motility disorders. With its goal of improving LES function, it helps alleviate symptoms and improve the overall quality of life for patients suffering from conditions like achalasia. If you have concerns about your esophageal health, consult with a healthcare professional who can provide guidance on the most appropriate treatment options for your specific condition.
