The Center of Excellence for Treatment of Barrett’s Esophagus is an alliance of numerous professionals from several clinical institutions, research organizations, and supporting services providing comprehensive and well-coordinated care for patients, as well as conducting research. This partnership has resulted in the introduction of new endoscopic treatments and the development of new optical technologies for non-invasive detection of cancer and dysplasia.

Photodynamic therapy for Barrett’s esophagus with high grade dysplasia was pioneered in 1990 at the Laser Center, located on the 4th floor of the Thompson Cancer Survival Center. The Laser Center was one of the first institutions to introduce Radiofrequency Ablation (RFA) for treatment of Barrett’s esophagus. Currently, the center provides an array of endoscopic treatment options for Barrett’s patients to include Endoscopic Mucosal Resection (EMR) using both cap assisted and ligation assisted techniques, radiofrequency ablation (BARRX) using HALO 60, HALO 90, HALO 360, HALO 360 Express, Through-the-Scope HALO, and HALO Ultra catheters, Neodymium-yttrium-aluminum-garnet (Nd:YAG) laser ablation,  as well as cryotherapy. Our medical staff have published extensively in medical and scientific journals (see publication list).

A Multidisciplinary Program By A Team of Experts: Bergein F. Overholt, M.D. John M. Haydek, M.D., Raj I. Narayani, M.D., and Masoud Panjehpour, Ph.D., have 27 Years of Experience in Managing Thousands of Barrett’s Patients.


We strive to provide state-of-the-art treatments for management of Barrett’s esophagus.

We are dedicated to achieving the best treatment outcomes and patient satisfaction through a partnership between healthcare providers, research institutions, and support services.


We will be the leaders in the application of endoscopic treatments for Barrett’s esophagus.
