Dr. Mallat recently participated in a multi-center study on the efficacy of cryotherapy for treating a pre-cancerous condition of the esophagus (known as Barrett’s esophagus). Cryotherapy is the application of a freezing mist sprayed directly on cancerous lesions through an endoscope. The findings suggested that cryotherapy is highly effective in eradicating pre-cancerous lesions of the esophagus. Dr. Mallat has been active in the application of cryotherapy in treating esophageal cancer. For more information, please see: Gastrointest Endosc 2010 Apr;71(4):680-5.
