Per-oral Endoscopic Myotomy (POEM)

Per-oral Endoscopic Myotomy (POEM) is a minimally-invasive procedure performed to help restore a patient’s ability to swallow food and liquids.

No external scars. No need to avoid food or the embarrassment of eating in public. The GW Medical Faculty Associates has a new addition to our services that can help patients who have swallowing difficulties, frequent regurgitation, and chest pain or weight loss. Per-oral Endoscopic Myotomy (POEM) is a minimally-invasive procedure performed to help restore a patient’s ability to swallow food and liquids. POEM is a safe alternative which can help patients recover more quickly compared to traditional surgery.

During the POEM procedure, patients are administered anesthesia and antibiotics through an IV insert, and our surgeons insert a flexible endoscope through the mouth to access the esophagus. Tiny surgical endoscopic attachments can be used to create a tunnel as the instruments are passed through the esophagus toward the stomach. This tunneling technique involves cutting of the esophagus’s inner layer muscle fibers that block food from flowing through the esophagus to the stomach. Thus, no external incisions will be made to the gastrointestinal area. There will be only one internal incision, which permits the endoscope to enter the esophagus. This same incision is closed with endoscopic clips when the procedure is finished. Following the procedure, patients are expected to stay under hospital care for monitoring.

Can I Benefit from POEM?

This surgical therapy procedure was developed for patients suffering from achalasia, a condition that is often misdiagnosed and causes difficulty in swallowing. The lower esophageal sphincter (LES) plays a major role in allowing food to access the stomach. As the LES sits at the junction of the stomach and esophagus, pressure creates contractions in the LES to help food travel down the esophagus and enter the stomach. In a patient dealing with achalasia, the LES has trouble relaxing and does not open and close as it normally should. It assumes a closed position, which creates the swallowing difficulties. POEM, however, is not limited to patients with achalasia. POEM is also used to help patients struggling with other esophageal disorders that are non-responsive to other treatments.

Our team at The GW Medical Faculty Associates will continue to embrace advanced and innovative technologies that will reduce invasiveness and improve our patients’ quality care.


There are three different types of fundoplications:

  • The Nissen Fundoplication
  • Toupet Fundoplicaiton
  • The DOR Fundoplication

The Nissen Fundoplication is the most common and effective long term anti-reflux procedure. Laparoscopic anti-reflux surgery involves reinforcement of the dysfunctional LES. Five small incisions (all < 1 inch) are used as opposed to a large “open” operation which may require a large 10-12 inch midline incision. A laparoscope is used as a camera to visualize and magnify the abdominal contents transmitting the images to monitors outside the body. Long thin instruments are used to wrap the top of the stomach around the lower portion of the esophagus to recreate and reinforce the dysfunctional LES. This is called a fundoplication or wrap.

The advantage of laparoscopic anti-reflux surgery include a smaller incision, less pain, shorter hospital stay, lower chance of future hernia formation, and an earlier return to work and normal activities.

A liquid diet is started the day after surgery and advanced to a soft diet as tolerated. Patients will need to continue on soft foods for approximately 2-4 weeks after surgery. The majority of patients spend one night in the hospital and are discharged home on the next day. Most patients return to work in less than one week depending on the physical requirements of their occupation. Patients return approximately two weeks after surgery for routine follow-up with their surgeon.

Non-surgical treatments for GERD?

The initial treatment of GERD involves lifestyle modification including dietary changes, avoiding alcohol/tobacco, and weight loss. Medical therapy is often required and is aimed at reducing acid production in the stomach. Surgical endoscopic procedures, which tighten the junction of the esophagus and stomach, are available for patients who do not respond to lifestyle changes or medical therapy.
