Diseases and Conditions

Achalasia

Treatment

Achalasia treatment focuses on relaxing or stretching open the lower esophageal sphincter so that food and liquid can move more easily through your digestive tract.

Specific treatment depends on your age, health condition and the severity of the achalasia.

Nonsurgical treatment

Nonsurgical options include:

  • Pneumatic dilation. A balloon is inserted by endoscopy into the center of the esophageal sphincter and inflated to enlarge the opening. This outpatient procedure may need to be repeated if the esophageal sphincter doesn't stay open. Nearly one-third of people treated with balloon dilation need repeat treatment within five years. This procedure requires sedation.
  • Botox (botulinum toxin type A). This muscle relaxant can be injected directly into the esophageal sphincter with an endoscopic needle. The injections may need to be repeated, and repeat injections may make it more difficult to perform surgery later if needed.

    Botox is generally recommended only for people who aren't good candidates for pneumatic dilation or surgery due to age or overall health. Botox injections typically do not last more than six months. A strong improvement from injection of Botox may help confirm a diagnosis of achalasia.

  • Medication. Your doctor might suggest muscle relaxants such as nitroglycerin (Nitrostat) or nifedipine (Procardia) before eating. These medications have limited treatment effect and severe side effects. Medications are generally considered only if you're not a candidate for pneumatic dilation or surgery, and Botox hasn't helped. This type of therapy is rarely indicated.

Surgery

Surgical options for treating achalasia include:

  • Heller myotomy. The surgeon cuts the muscle at the lower end of the esophageal sphincter to allow food to pass more easily into the stomach. The procedure can be done noninvasively (laparoscopic Heller myotomy). Some people who have a Heller myotomy may later develop gastroesophageal reflux disease (GERD).

    To avoid future problems with GERD, a procedure known as fundoplication might be performed at the same time as a Heller myotomy. In fundoplication, the surgeon wraps the top of your stomach around the lower esophagus to create an anti-reflux valve, preventing acid from coming back (GERD) into the esophagus. Fundoplication is usually done with a minimally invasive (laparoscopic) procedure.

  • Peroral endoscopic myotomy (POEM). In the POEM procedure, the surgeon uses an endoscope inserted through your mouth and down your throat to create an incision in the inside lining of your esophagus. Then, as in a Heller myotomy, the surgeon cuts the muscle at the lower end of the esophageal sphincter.

    POEM may also be combined with or followed by later fundoplication to help prevent GERD. Some patients who have a POEM and develop GERD after the procedure are treated with daily oral medication.
