Photodynamic Therapy for the Treatment of Barrett's Esophagus

Photodynamic Therapy involves the injection of a light sensitizing drug and use of a red light laser passed through the endoscope to activate the medication in the abnormal Barrett's esophagus mucosa to destroy the tissue.

Photodynamic therapy has been approved for the treatment of Barrett's esophagus with high grade dysplasia. Kenneth Wang, M.D., has been one of the pioneers in this field and has been performing photodynamic therapy for over 12 years. In a current study supported by the National Cancer Institute, patients with Barrett's esophagus and and early esophageal cancer have molecular testing done to determine if they will respond to photodynamic therapy.
