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.

What Our Patients Are Saying

Scott S.
Talking about Rasa Zarnegar, M.D.

"Dr. Zarnegar is my hero! Not that I have any medical expertise or experience but he is excellent all around and I highly recommend him if you need surgical care. Take it from someone who never had surgery in his entire life. I did plenty of research in my efforts to line up the right doctor at the right time to get a hernia repaired, one that I had been prolonging for years. I had consulted with nearly a half a dozen surgeons from the Eastern end of Long Island to NYC, from some of the top medical institutions. I always knew I had a right inguinal hernia, but among the consultations I had, Dr. Zarnegar was the only surgeon to identify that I had not just one but three hernias: left and right inguinal hernias plus an umbilical hernia. Only one other surgeon picked up on the umbilical hernia in addition to the right inguinal. Given the cost of healthcare today, can you imagine what the out-of-pocket expense would have been if I had to endure 3 separate surgeries rather than the one"

"I loved the fact that I felt comfortable, safe and sound during my visit to the clinic with this world wide pandemic COVID19 that safety measures are still exercised, and keeping patients at a distant and also without hesitation during my visit with Dr. Cheguevara, Afaneh and nurses all showed their strong ethics, while privately keeping my matters confidential they were caring, kind and professional in addressing my health situations and quickly assigned a date for surgery to repair my belly hernia. Much appreciated. Thank you in advance."
