Esophageal Achalasia Treatment: Best Options, Procedures, and What to Expect

Esophageal achalasia treatment focuses on relaxing or cutting the lower esophageal sphincter (LES) so food can pass into the stomach. There is no cure. The nerves that control the esophagus are permanently damaged, but symptoms can be managed well enough for most patients to eat and live normally.

Achalasia affects roughly 1 in 100,000 people per year. It’s rare, frequently misdiagnosed, and often mistaken for GERD for years before the correct diagnosis. The average patient waits 4 to 6 years between first symptoms and confirmed diagnosis. Early, appropriate treatment prevents serious complications like megaesophagus, where the esophagus stretches and loses function permanently.

How Esophageal Achalasia Is Treated

The LES is a ring of muscle at the bottom of the esophagus. In achalasia, it stays tight and doesn’t relax when you swallow. Food backs up. The esophagus can’t push it through.

Esophageal achalasia treatment targets this muscle directly. Every effective treatment, whether endoscopic or surgical, either stretches, cuts, or weakens that muscle ring. Nothing restores the damaged nerves. The treatment removes the blockage, not the cause.

Three treatment tracks exist:

• Endoscopic procedures: Work through the mouth, no external incisions
• Surgery: Open or laparoscopic cutting of the LES muscle
• Medications: Weak, short-term option only when procedures aren’t possible

Best Treatment Options for Achalasia

The best treatment options for achalasia in current clinical practice are the POEM procedure and laparoscopic Heller myotomy. Both cut the LES muscle to allow food to pass. Both produce long-term symptom relief in over 85% of patients.

Here’s how the main options compare:

POEM has the highest success rate and the least external trauma. The tradeoff is a higher rate of acid reflux after the procedure. Heller myotomy includes an anti-reflux wrap (Dor fundoplication) that reduces this risk.

POEM Procedure for Achalasia

What Is POEM (Peroral Endoscopic Myotomy)?

POEM procedure for achalasia is a minimally invasive technique where a surgeon cuts the LES muscle using an endoscope passed through the mouth. No skin incisions. No external scarring. The patient is under general anesthesia for the entire procedure.

POEM was first performed in Japan in 2008 by Dr. Haruhiro Inoue at Showa University. It’s now performed in major tertiary centers worldwide. The American Society for Gastrointestinal Endoscopy (ASGE) recommends it as a first-line option alongside Heller myotomy.

How It Works

The surgeon creates a small cut in the esophageal lining, about 10 to 15 cm above the LES. A tunnel forms between the inner and outer layers of the esophagus wall. Inside this tunnel, the surgeon cuts the circular muscle fibers of the LES. The tunnel is then closed with small clips.

The entire procedure takes 60 to 90 minutes. Most patients go home within 1 to 2 days. Soft foods continue for 2 weeks post-procedure.

Benefits and Limitations

Benefits:

• No external incisions
• 90 to 95% symptom relief at 2-year follow-up
• Works for all achalasia subtypes, including Type III (spastic), which Heller myotomy handles poorly
• Shorter recovery than surgery

Limitations:

• GERD develops in up to 46% of POEM patients post-procedure because there’s no anti-reflux repair built into the technique
• Long-term acid suppression with PPIs is often required afterward
• Requires a skilled endoscopist; not available at every hospital

Surgical Treatment for Achalasia

Heller Myotomy

Laparoscopic Heller myotomy is the surgical standard for esophageal achalasia treatment. The surgeon makes 4 to 5 small abdominal incisions and cuts the LES muscle from the outside.

The procedure always includes a partial fundoplication, usually a Dor (anterior) wrap, where the top of the stomach wraps partially around the esophagus to prevent acid reflux. This is the main structural advantage over POEM.

• Success rate: 85 to 90% at 5 years. Reflux rate: 20 to 30%, significantly lower than POEM without additional intervention.
• Recovery time : 1 to 2 weeks before returning to light activity. Full recovery in 4 to 6 weeks.

When Surgery Is Needed

Surgery is the preferred path when:

• POEM is unavailable at the treating center
• The patient has a large hiatal hernia that needs simultaneous repair
• Previous endoscopic treatments (pneumatic dilation or Botox) have failed
• The patient has Type I or Type II achalasia with no prior treatments

Medications for Achalasia

Medications are the weakest form of esophageal achalasia treatment. They don’t fix the structural problem. They only partially relax the LES.

Two medication types are used:

• Calcium channel blockers (nifedipine): Taken sublingually 30 to 45 minutes before meals. Relaxes smooth muscle. Effective in about 30% of patients short-term. Side effects include headache, low blood pressure, and ankle swelling.
• Nitrates (isosorbide dinitrate): Similar mechanism. Similar limitations. Rarely used as primary treatment.

Medications are appropriate only for elderly patients who cannot tolerate procedures, or as a short bridge while waiting for a procedure date. They lose effectiveness within months in most patients.

Difficulty Swallowing and Achalasia Treatment

Difficulty swallowing is the primary symptom most patients report. Food sticks in the chest. Liquids sometimes cause more trouble than solids in early-stage achalasia, which is the opposite of most other swallowing conditions.

Before procedures, patients manage dysphagia by:

• Eating slowly, one small bite at a time
• Drinking water between bites to help push food through
• Avoiding dry, dense foods like bread crusts or dry chicken
• Standing or walking after meals to use gravity

After POEM or Heller myotomy, swallowing improves within 1 to 2 weeks in most patients. A 2021 study in Gastroenterology reported that 91% of POEM patients showed significant dysphagia improvement at 3-month follow-up.

Pneumatic dilation is a non-surgical option for difficulty swallowing in achalasia treatment. A balloon is inflated inside the LES during endoscopy to stretch and partially tear the muscle. It requires 1 to 3 sessions and has a 70 to 80% success rate, but symptoms return in 50% of patients within 5 years.

Nerve Damage and Achalasia Management

Achalasia results from the destruction of ganglion cells in the myenteric plexus, the nerve network that coordinates esophageal muscle movement. Researchers believe this happens through an autoimmune process, possibly triggered by a viral infection. Herpes simplex virus type 1 (HSV-1) has been found in esophageal tissue samples from achalasia patients in multiple studies.

Because nerve regeneration doesn’t happen in the esophagus, treatment never restores normal function. The esophagus cannot push food through with normal peristalsis again. Treatment only removes the obstruction at the bottom.

Weight Loss and Achalasia Management

Weight loss due to achalasia management is a real clinical concern. Patients often lose 5 to 15 kg before diagnosis because eating becomes painful, slow, and unpredictable.

Nutritional strategies before treatment:

• Prioritize high-calorie liquids: smoothies, protein shakes, whole milk (if tolerated)
• Eat 5 to 6 small meals instead of 3 large ones
• Avoid foods that consistently get stuck; track which textures cause the most trouble
• Warm liquids often pass better than cold ones because warmth relaxes esophageal muscle slightly

After successful esophageal achalasia treatment, most patients regain lost weight within 3 to 6 months. A 2019 report in Diseases of the Esophagus found that patients who underwent POEM regained an average of 4.2 kg within 6 months post-procedure.

Choosing the Right Treatment for Achalasia

The right treatment depends on four factors:

• Age and health status: Elderly or high-surgical-risk patients do better with pneumatic dilation or Botox, even if long-term outcomes are weaker. POEM carries lower surgical risk than Heller myotomy for frail patients.
• Achalasia subtype: Type III (spastic achalasia) responds poorly to dilation and surgery. POEM is the preferred option because the myotomy can extend higher up the esophagus.
• Reflux history: Patients with pre-existing GERD should discuss the higher post-POEM reflux rate with their doctor. Heller myotomy with fundoplication may be the safer choice.
• Access to expertise: POEM requires specific training. Not every hospital offers it. Heller myotomy is more widely available.

Complications of Achalasia Treatment

Every form of esophageal achalasia treatment carries specific risks.

After POEM:

• GERD in up to 46% of patients (managed with daily PPIs)
• Mucosal perforation during the tunnel creation (less than 1%)
• Air leak into the chest cavity (capnomediastinum), usually resolves on its own

After Heller Myotomy:

• Esophageal perforation (1 to 2%)
• GERD in 20 to 30% of patients
• Incomplete myotomy requiring repeat treatment (5 to 10%)

After Pneumatic Dilation:

• Esophageal perforation (1 to 3%), the most serious risk
• Symptom recurrence requiring repeat dilation within 5 years in 50% of patients

After Botox Injection:

• Chest pain in the first 48 hours (30% of patients)
• Fibrotic scarring at the injection site, which makes future POEM or surgery harder

Long-Term Outlook After Treatment

Most patients experience significant improvement after esophageal achalasia treatment. POEM and Heller myotomy maintain symptom relief in 80 to 85% of patients at 5 years.

Recurrence happens. About 10 to 20% of patients need a repeat procedure within 10 years. Regular follow-up with a gastroenterologist is required, typically:

• At 3 months post-procedure
• At 12 months post-procedure
• Then every 2 to 3 years for life

Patients with longstanding, untreated achalasia face a 16-fold higher risk of esophageal squamous cell carcinoma compared to the general population. Surveillance endoscopy every 3 years is recommended for patients who had symptoms for more than 10 years before diagnosis.

Lifestyle Changes That Support Treatment

Lifestyle changes don’t treat the underlying problem, but they reduce symptom burden before and after procedures.

• Eat slowly. One bite, chew thoroughly, swallow fully before the next bite.
• Keep meals small. Large volumes increase esophageal pressure and pain.
• Stay upright for 45 to 60 minutes after eating. Gravity assists food transit into the stomach.
• Avoid eating within 3 hours of bedtime. Food sitting in the esophagus overnight causes discomfort and increases aspiration risk.
• Sleep with the head of the bed elevated 6 to 8 inches, especially if reflux develops post-procedure.

FAQs: Esophageal Achalasia Treatment

What is the best treatment for achalasia?

POEM is the most effective esophageal achalasia treatment with a 90 to 95% success rate at 2 years. Laparoscopic Heller myotomy is the best surgical alternative at 85 to 90% success. POEM wins on efficacy; Heller myotomy wins on lower post-procedure reflux rates.

Can achalasia be cured?

No. Esophageal achalasia treatment manages symptoms but doesn’t repair the destroyed nerve cells that caused the condition. The esophagus never regains normal peristalsis. Treatment removes the obstruction; it doesn’t restore function.

What is the POEM procedure?

POEM procedure for achalasia is a surgery performed entirely through the mouth using an endoscope. The surgeon tunnels between esophageal wall layers and cuts the LES muscle from the inside. No skin incisions. Procedure takes 60 to 90 minutes under general anesthesia.

Is surgery necessary for achalasia?

No. POEM achieves surgical-level results without open or laparoscopic incisions. Surgery (Heller myotomy) is preferred when POEM isn’t available locally, when a hiatal hernia needs simultaneous repair, or when the patient has pre-existing severe reflux.

Does treatment improve swallowing?

Yes. Difficulty swallowing improve during achalasia treatment through POEM or Heller myotomy, which improves dysphagia in over 90% of patients within 2 to 4 weeks. Pneumatic dilation improves swallowing in 70 to 80% of patients, but 50% need repeat treatment within 5 years.

Can achalasia cause weight loss?

Yes. Weight loss due to achalasia management before treatment averages 5 to 15 kg. After successful POEM or Heller myotomy, patients typically regain 4 to 5 kg within 6 months as eating becomes comfortable again.

Are medications effective?

No, not reliably. Calcium channel blockers and nitrates help about 30% of patients short-term. They lose effectiveness within months, and side effects like low blood pressure and headaches are common. Medications are a bridge, not a solution.

Is long-term follow-up needed?

Yes. Even after successful esophageal achalasia treatment, endoscopy every 2 to 3 years is recommended for life. Patients with more than 10 years of symptoms before diagnosis need cancer surveillance every 3 years due to elevated esophageal cancer risk.
