At NewYork-Presbyterian Hospital/Weill Cornell Medical Center the esophageal motility unit is directed by Rasa Zarnegar, MD. He is specially trained in the diagnosis and surgical management of esophageal motility disorders. He works closely with renowned gastroenterologists who provide endoscopic techniques for the management and treatment of esophageal disorders.

Difficulty swallowing liquids or solids, heartburn, regurgitation, and atypical (or non-cardiac) chest pain may be symptoms of an esophageal motility disorder. Typical esophageal motility disorders include gastroesophageal reflux disease (GERD), dysphagia, achalasia, and esophageal spasm.

The esophageal motility unit at NewYork-Presbyterian Hospital/Weill Cornell Medical Center focuses on the diagnosis and management of esophageal motility disorders. The unit provides diagnostic tests including esophageal manometry and pH studies. These tests are typically required to diagnose:

  1. GERD
  2. Achalasia
  3. Diffuse Esophageal Spasm
  4. Sphincter disorders

Nearly all patients referred to our institution will require an Esopageal Manomtery and sometimes a pH probe to determine the cause of their symptoms. Most studies have shown that reliance on symptoms alone has a high failure rate of surgical management in esophageal disorders.

Talking about Rasa Zarnegar, M.D.

"Dr Zarnegar and his team are truly exceptional. Every detail is taken care. There is no wait and you definitely receive personalized attention and treatment approach. I have been a patient for almost 4 years due to my acid reflux issues and finally had the Hill procedure last March. My experience was super positive and the surgery 100% life changing. Dr Zarnegar is a superb diagnostician (which is what you really want) and a highly skilled surgeon. He is super confident but at the same time very approachable. Everyone in his team is responsive to all questions and concerns and you totally feel they all want what is best for you. Many physicians handle these kind of surgeries but if you are hoping for unique approach, competence and extraordinary results this is the doctor/practice for you."
