Peroral Endoscopic Myotomy (POEM)

What is POEM?
Peroral Endoscopic Myotomy, commonly known as POEM, is an advanced minimally invasive endoscopic procedure used to treat swallowing disorders, particularly achalasia. Achalasia is a condition in which the muscles of the esophagus and the lower esophageal sphincter fail to relax properly, making it difficult for food and liquids to pass into the stomach. POEM was developed as an alternative to traditional surgical treatments and has become an important innovation in therapeutic gastroenterology. During the procedure, an endoscope is inserted through the mouth, allowing physicians to access the inner layers of the esophagus without external incisions. The tight muscle fibers causing obstruction are carefully divided to improve swallowing function. Because POEM is incision-free and highly precise, it offers shorter recovery times and reduced discomfort compared to conventional surgery while maintaining excellent long-term treatment outcomes.
Who Needs POEM?
POEM is primarily recommended for patients diagnosed with achalasia or other esophageal motility disorders that interfere with normal swallowing. Common symptoms include difficulty swallowing, chest discomfort, regurgitation of food, chronic coughing, and unintended weight loss. Some patients may also experience nighttime aspiration or recurrent respiratory issues due to food remaining in the esophagus. POEM may be particularly beneficial for patients who have not responded adequately to medications or less invasive treatments such as balloon dilation or botulinum toxin injections. It is also considered an effective option for recurrent achalasia after previous surgical treatment. Before recommending POEM, specialists perform comprehensive evaluations including endoscopy, esophageal manometry, and imaging studies to determine the severity of the disorder and the most appropriate treatment strategy.
How is the POEM Procedure Performed?
POEM is performed under general anesthesia in a specialized endoscopy unit. During the procedure, a flexible endoscope is inserted through the mouth into the esophagus. The physician creates a small entry point within the esophageal lining and forms a tunnel through the inner wall layers. Through this tunnel, the abnormal esophageal muscles responsible for the swallowing problem are carefully cut. After completing the myotomy, the entry site is securely closed using endoscopic clips. The procedure usually takes one to two hours, depending on the complexity of the case. Since POEM does not require external incisions, patients generally experience less postoperative pain and faster recovery compared to open or laparoscopic surgery. Modern endoscopic technologies have significantly improved the safety and precision of the procedure.
Benefits of POEM
One of the major advantages of POEM is that it provides a minimally invasive solution for complex esophageal motility disorders. Because the procedure is performed entirely through the mouth, there are no visible surgical scars. Patients often experience rapid improvement in swallowing function and quality of life shortly after treatment. POEM also offers greater flexibility in treating longer segments of abnormal muscle compared to some traditional surgical techniques. Recovery time is generally shorter, allowing patients to return to normal activities more quickly. In addition, POEM has shown high long-term success rates in relieving symptoms of achalasia. The combination of precision, effectiveness, and minimally invasive access has made POEM an increasingly preferred treatment option worldwide.
Risks and Possible Complications
Although POEM is considered safe and effective, it does carry some potential risks and complications. The most common concern is gastroesophageal reflux disease (GERD), which may develop after the lower esophageal sphincter muscle is cut. Some patients may require acid-suppressive medications following the procedure. Other possible complications include bleeding, infection, air leakage into surrounding tissues, or injury to the esophagus, although these are relatively rare when performed by experienced specialists. Careful patient selection and advanced procedural techniques significantly reduce complication risks. Patients are closely monitored after the procedure to ensure early detection and management of any issues. Overall, the benefits of POEM generally outweigh the risks for appropriately selected patients.
Recovery After POEM
Recovery after POEM is usually faster than traditional surgery due to the minimally invasive nature of the procedure. Most patients remain in the hospital for observation for one or two days. Initially, a liquid diet is recommended before gradually progressing to soft foods and eventually regular meals. Patients are advised to follow dietary instructions carefully to support healing and reduce discomfort. Mild chest discomfort or sore throat may occur temporarily but generally resolves quickly. Follow-up evaluations help assess swallowing improvement and monitor for reflux symptoms. Long-term lifestyle adjustments, including avoiding late-night meals and maintaining a healthy diet, may further support recovery. With appropriate follow-up care, most patients achieve significant and lasting symptom relief.
POEM Cost and Price Factors
The cost of POEM treatment varies depending on several important factors rather than a fixed standard price. The complexity of the patient’s condition, the experience of the gastroenterology and endoscopy team, and the technological capabilities of the healthcare facility all influence overall treatment costs. Advanced endoscopic procedures such as POEM require highly specialized expertise and equipment, which can impact pricing structures.
Treatment programs often include pre-procedure evaluations such as endoscopy, esophageal manometry, imaging studies, anesthesia services, hospitalization, and follow-up care. For international patients, additional services such as accommodation, translation support, and transportation may also be included within comprehensive medical travel packages.
Rather than focusing solely on cost, patients are encouraged to evaluate procedural expertise, safety standards, and long-term success rates when selecting a treatment center. A personalized consultation provides the most accurate assessment of treatment needs and associated expenses.
FAQ
What conditions can POEM treat?
POEM is primarily used to treat achalasia, but it may also be effective for other esophageal motility disorders involving abnormal muscle contractions and swallowing difficulties.
Is POEM better than traditional surgery?
POEM offers several advantages, including no external incisions, faster recovery, and high success rates. However, the best treatment depends on the patient’s condition and medical evaluation.
How long does the POEM procedure take?
The procedure usually takes between one and two hours, depending on the complexity of the case.
Is POEM a permanent solution?
Many patients experience long-term symptom relief after POEM, although regular follow-up is important to monitor outcomes and manage reflux if necessary.
What can I eat after POEM?
Patients typically begin with liquids and gradually transition to soft foods before returning to a regular diet based on medical recommendations.
