Best Gastroenterologists for Peroral Endoscopic Myotomy (POEM) in India

GERD is a condition in which the lower esophageal sphincter — the muscular valve between the esophagus and stomach — fails to close properly, allowing stomach acid to reflux upward and irritate the esophagus on a recurrent basis. Unlike occasional heartburn, GERD is defined by its frequency, its impact on quality of life, and the potential it carries for esophageal injury.

The most common symptoms include persistent heartburn (a burning sensation behind the breastbone), regurgitation of acid or food, difficulty swallowing, chronic cough, hoarseness, and a sensation of a lump in the throat. Some individuals experience atypical presentations such as chest pain, worsening asthma, or disrupted sleep, which can make the condition easy to overlook or confuse with other disorders. Symptoms alone are not sufficient to establish a diagnosis or determine severity, as they do not reliably indicate the degree of esophageal damage or underlying functional abnormalities.

Diagnosis typically begins with a detailed clinical history and symptom assessment, and may be supported by an upper endoscopy (gastroscopy) to directly visualize the esophageal lining and detect complications such as esophagitis, Barrett's esophagus, or hiatal hernia. Esophageal manometry is used to measure the pressure and function of the esophageal muscles and lower sphincter, which is particularly important before any surgical planning. Ambulatory pH monitoring — recording acid levels in the esophagus over 24 hours — is the most objective tool for confirming pathological acid reflux and grading its severity; the Los Angeles (LA) Classification is commonly used to grade endoscopic findings of esophagitis from A (mildest) to D (most severe).

Treatment for GERD is tailored to the individual based on symptom severity, investigation findings, the presence of complications, and the patient's overall health profile. Mild to moderate GERD is often managed effectively with lifestyle modifications and acid-suppressing medications, while persistent, severe, or complicated cases — or those in which long-term medication is not desired or tolerated — may be candidates for procedural intervention. Surgical options available in our directory include Nissen fundoplication (anti-reflux surgery), which reinforces the lower esophageal sphincter, and for selected patients with coexisting esophageal motility disorders, Peroral Endoscopic Myotomy (POEM) may be discussed as part of a broader management plan; the most appropriate pathway depends on individual assessment by a qualified clinician.

Non-surgical management is a well-established and effective first-line pathway for the majority of GERD patients, encompassing dietary and lifestyle changes (weight loss, avoiding trigger foods, elevating the head of the bed, stopping smoking), and pharmacological therapy including proton pump inhibitors (PPIs) or H2-receptor antagonists to reduce gastric acid. Ongoing monitoring is an important component of non-surgical care, particularly for patients with confirmed Barrett's esophagus, who require regular endoscopic surveillance according to established clinical guidelines. Surgery is generally considered when symptoms are not adequately controlled by medication, when patients prefer to avoid long-term drug therapy, or when specific anatomical findings such as a significant hiatal hernia are identified.

Peroral Endoscopic Myotomy (POEM) may be considered only when it is appropriate for the confirmed diagnosis and the expected benefit outweighs the individual risks. The decision may depend on symptom severity, investigation results, previous treatment, overall health and the patient's goals. A specialist should discuss alternatives and recovery before any procedure is planned.

GERD is typically evaluated and managed by a gastroenterologist, who oversees diagnosis, medical treatment, and endoscopic assessment, and — when surgical intervention is being considered — by a surgical gastroenterologist or upper gastrointestinal surgeon with specific experience in anti-reflux procedures. In complex cases involving atypical symptoms or motility disorders, a multidisciplinary approach incorporating both specialties is advisable.

When selecting a specialist for GERD, it is worth comparing their experience with the full diagnostic workup — including endoscopy, esophageal manometry, and pH studies — and, if surgery may be relevant, their documented volume and outcomes in anti-reflux procedures. Access to a hospital or center where gastroenterology and surgical gastroenterology teams collaborate closely, along with clear arrangements for postoperative or long-term follow-up, is an important practical consideration.

Share a concise medical summary, symptom timeline, previous diagnoses, investigation and imaging reports, procedure or biopsy reports where relevant, current medicines, allergies and related treatment records. Provide clear copies with translations when needed. The reviewing doctor may request additional information before giving an opinion.

Our care coordination team can review the initial information, help identify suitable doctors and hospitals, request a medical opinion where available, explain next steps and indicative cost information, and support practical planning before travel. A remote opinion does not replace an in-person examination or emergency care.
