About this doctor:

Steven DeMeester, MD, Professor of Surgery, is board certified in General Surgery as well as Cardiovascular and Thoracic Surgery. He is an acknowledged international leader in the field of esophageal surgery. His practice focuses on esophageal disorders of all types, from reflux disease and paraesophageal hiatal hernias to esophageal cancer and all forms of esophageal motility disorders including achalasia. Patients from across America and the globe travel to be treated by him. He is a pioneer in the minimally invasive management of esophageal disorders, including the Per-Oral Endoscopic Myotomy (POEM) procedure for achalasia and the LINX device for gastroesophageal reflux disease. Further, he has extensive experience with endoscopic therapy for benign and malignant gastric and esophageal lesions. A particular focus for Dr. DeMeester is the area of Barrett’s esophagus, and he developed the National Registry of Barrett’s Esophagus and Antireflux Surgery. He has published as author or co-author over 130 peer-reviewed papers, 15 book chapters, and has given invited lectures around the world. His accomplishments have earned him membership in elite societies including the American Surgical Association and the American Association of Thoracic Surgeons. Innovative and forward thinking, his primary focus is on benign and malignant esophageal disorders, yet he also treats a broad array of complex pulmonary and tracheal disorders. Dr. DeMeester earned his medical degree at Loyola Stritch School of Medicine in Chicago, then completed a residency in General Surgery at the University of Michigan. Subsequently he completed a Cardiothoracic Surgery residency at Washington University in St. Louis. To gain further expertise with complex foregut problems and to refine his skills in minimally invasive laparoscopic and thoracoscopic procedures he undertook a one-year esophageal surgery fellowship at the University of Southern California. He joined the faculty of the USC Department of Surgery in 1997.
