For someone with achalasia, eating can become an exhausting calculation: small bites, plenty of water, avoiding meals before bed, and worrying that food may stick in the chest. The POEM procedure achalasia treatment offers an incisionless way to address the muscle problem behind those symptoms. It is designed to help the lower esophageal sphincter relax so food and liquid can move into the stomach more normally.
Achalasia is uncommon, but its effect on daily life can be significant. Symptoms often develop gradually and may be mistaken for acid reflux, anxiety, or a simple swallowing issue. A careful evaluation is essential, because the right treatment depends on the type of achalasia, the shape and function of the esophagus, prior procedures, and each patient’s overall health.
What Achalasia Does to the Esophagus
The esophagus is the muscular tube that carries food from the mouth to the stomach. At its lower end is a ring of muscle called the lower esophageal sphincter. Normally, this muscle opens during swallowing and closes afterward.
With achalasia, the lower esophageal sphincter does not relax as it should. The esophagus may also lose the coordinated muscle contractions that push food downward. As a result, food, liquids, and saliva can collect above the stomach rather than passing through easily.
Common symptoms include trouble swallowing solids and liquids, regurgitation of undigested food, chest pressure or pain, nighttime coughing, unintended weight loss, and recurring heartburn-like discomfort. Some patients find that symptoms worsen over time, while others have periods of relative relief. Persistent swallowing problems deserve prompt medical attention, particularly when weight loss, dehydration, or aspiration are concerns.
How the POEM Procedure for Achalasia Works
POEM stands for peroral endoscopic myotomy. It is performed through the mouth using a flexible endoscope, so there are no abdominal incisions. During the procedure, the surgeon creates a small entry point in the inner lining of the esophagus and forms a tunnel within its wall. Through that tunnel, the tight muscle fibers at the lower esophageal sphincter are carefully divided.
The goal is not to remove the esophagus or change the route of digestion. Instead, POEM reduces the abnormal resistance at the point where the esophagus meets the stomach. Once that muscular barrier is loosened, swallowing can become substantially easier.
The entry point in the esophageal lining is closed with endoscopic clips. Patients are under general anesthesia for the procedure and are closely monitored afterward. Because POEM is incisionless, it may reduce the discomfort and recovery burden associated with more invasive approaches. That said, it remains a specialized procedure that requires careful planning and experienced surgical and anesthesia care.
Why the Length of the Myotomy Matters
Achalasia is not identical from patient to patient. High-resolution esophageal manometry, a test that measures pressure and muscle movement during swallowing, helps identify the achalasia subtype. In some forms of the condition, including spastic achalasia, abnormal contractions can affect a longer section of the esophagus.
One advantage of POEM is that the muscle division can be tailored in length and location. This flexibility may be particularly useful when spasm extends higher in the esophagus. The appropriate approach still depends on the full clinical picture, not on one test result alone.
Who May Be a Candidate for POEM?
POEM may be considered for adults with confirmed achalasia who are medically appropriate candidates for anesthesia and endoscopic surgery. It can be used for newly diagnosed achalasia and, in selected cases, for people whose symptoms persist or return after prior treatments such as pneumatic dilation, Botox injection, or Heller myotomy.
Before recommending treatment, a specialist typically confirms the diagnosis with a combination of upper endoscopy, barium swallow imaging, and esophageal manometry. An upper endoscopy is especially important because other conditions, including a narrowing or tumor near the stomach entrance, can sometimes imitate achalasia symptoms.
The decision between POEM and laparoscopic Heller myotomy should be individualized. Both procedures are established options that aim to relieve the tight lower esophageal sphincter. A Heller myotomy is performed through small abdominal incisions and is often paired with a partial fundoplication to help limit reflux. POEM is performed through the mouth and can provide greater flexibility in the myotomy length, but it does not include an anti-reflux procedure at the same time.
That difference matters. For a patient with severe reflux before treatment, a large hiatal hernia, or anatomy that may benefit from a surgical anti-reflux repair, a laparoscopic approach may be preferable. For others, POEM may offer an excellent incisionless option. The best choice should reflect symptoms, testing, anatomy, prior treatment, and the patient’s priorities.
Benefits and Trade-Offs to Discuss
The main potential benefit of POEM is meaningful improvement in swallowing without external incisions. Many patients are able to return to a more normal eating pattern after healing and dietary progression. The procedure can also be effective for difficult spastic forms of achalasia and for some patients who have had prior therapy.
However, no procedure is without risk. Bleeding, infection, injury to the esophageal lining, air leakage into surrounding tissues, and anesthesia-related complications are possible, although patients are monitored closely to identify and manage concerns early. Rarely, additional treatment may be needed.
Reflux is one of the most important longer-term considerations. The same muscle division that improves swallowing can make it easier for stomach acid to travel upward into the esophagus. Some people have noticeable heartburn or regurgitation after POEM, while others have acid exposure without obvious symptoms. Follow-up may include symptom review, endoscopy, pH testing, and acid-reducing medication when appropriate. Long-term surveillance and treatment plans should be personalized rather than based only on how a patient feels day to day.
Preparing for the Procedure
Preparation instructions vary based on medical history and medications. Patients are generally asked to follow a modified diet before POEM so the esophagus can be as clear as possible. This may include liquids for a period of time before the procedure. Medications that affect blood clotting, diabetes management, or anesthesia may need special instructions.
A thorough consultation should also address prior abdominal or esophageal surgery, lung disease, sleep apnea, heart conditions, allergies, and current medications. Patients who have been regurgitating food at night should mention this clearly, as it can affect anesthesia planning and aspiration precautions.
It is wise to arrange transportation home and practical help for the first day or two after discharge. Asking questions beforehand can reduce uncertainty: How long is the expected hospital stay? What symptoms are normal during recovery? Who should be called after hours? When can work, exercise, and regular foods resume?
Recovery After POEM
Many patients stay overnight for observation. The care team may obtain imaging or perform other checks before starting liquids to ensure the esophagus is healing appropriately. Diet advancement is gradual, often moving from clear liquids to full liquids, soft foods, and then more regular textures over the following weeks.
Temporary chest discomfort, sore throat, bloating, or fatigue can occur. These symptoms should steadily improve. Severe chest pain, fever, shortness of breath, difficulty keeping liquids down, vomiting blood, black stools, or worsening swallowing problems require immediate medical attention.
Recovery is not only about the first few days. Follow-up visits help confirm that swallowing is improving and that reflux is being recognized and treated when needed. Patients may also need guidance on meal pacing, hydration, food textures, and the timing of medications as they return to regular routines.
Choosing Specialized, Patient-First Care
Achalasia treatment is highly technical, but the experience should never feel impersonal. At GI Surgical Specialists, the evaluation begins by listening closely to how swallowing symptoms affect meals, sleep, work, social plans, and confidence. Diagnostic findings and treatment options can then be explained in clear terms, including when an incisionless POEM approach may fit and when another treatment may better serve the patient’s long-term digestive health.
The most helpful next step is a consultation with a specialist who treats achalasia regularly and can review the complete picture. Relief often begins with a clear diagnosis, an honest discussion of trade-offs, and a treatment plan built around helping you eat, sleep, and live more comfortably again.
