Esophageal dilation, or pneumatic balloon dilation, is a minimally invasive procedure offered at GastroExperts to treat achalasia, a condition affecting swallowing. In achalasia, the lower esophageal sphincter (LES), the muscular valve at the end of the esophagus, fails to relax properly, making it difficult for food to pass into the stomach.
A highly skilled gastroenterologist guides a thin, flexible instrument called an endoscope through the mouth and into the esophagus. The endoscope has a camera at its tip to visualise the LES.
The balloon is then inflated with air or water for a controlled period, gently stretching and weakening the LES muscle fibers. This widens the opening, allowing food to pass easily into the stomach.
A deflated balloon is attached to the end of the endoscope and carefully positioned across the tight LES.
After deflation and removal of the balloon, the gastroenterologist will assess the effectiveness of the dilation using fluoroscopy (X-ray imaging) or by observing the passage of fluids through the esophagus.
Esophageal dilation offers a less invasive alternative to surgery for treating achalasia.
Successful dilation can significantly improve swallowing ability and reduce symptoms like chest pain and regurgitation.
Esophageal dilation is typically performed on an outpatient basis, allowing you to return home the same day.
Compared to surgery, esophageal dilation offers a faster recovery time with minimal discomfort.
Esophageal dilation is generally considered the first-line treatment for patients with achalasia who are good surgical candidates. However, it’s only suitable for some. Your gastroenterologist will consider factors like your overall health, severity of symptoms, and response to other therapies before recommending dilation.
Esophageal dilation is usually performed under sedation. You might experience throat discomfort during the procedure, but pain is typically well-managed with medication.
You will be monitored briefly after the procedure and discharged home with instructions. You might experience a sore throat or mild chest discomfort for a day or two, which can be managed with pain medication.
Esophageal dilation is generally safe, but there's a small risk of complications like bleeding, perforation (a tear in the esophagus), or infection. Your gastroenterologist will discuss these risks in detail before the procedure.
The success rate of esophageal dilation varies, but it can significantly improve swallowing function in many patients. Repeat procedures might be necessary in some cases.
Our team of gastroenterologists at GastroExperts are experts in performing esophageal dilation. We use advanced techniques and prioritize patient comfort throughout the process. If you experience difficulty swallowing and have been diagnosed with achalasia, contact GastroExperts to schedule a consultation with one of our gastroenterologists to discuss if esophageal dilation is the right treatment.
