Restech’s pH system was the highlight of new research presented by Dr. Ezra Teitelbaum at the 2017 American College of Surgeons’session on Novel Endoscopic and Minimally Invasive Techniques for Esophageal Dysmotility and Reflux Disease. Dr. Teitelbaum (Assistant Professor of Surgery and Medical Education at Northwestern University) collaborated with Dr. Steven DeMeester (President and Executive Director of the Foundation for Research and Education in Esophageal and Foregut Disorders) on a study comparing the results of different pH monitoring tests in patients off antisecretory medications.
