Wong, MD, Professor of Medicine, Case Western Reserve University, Cleveland, OH

The VTI Endoscopic Doppler System* (E-DOP) For endoscopic hemostasis, the Doppler probe has allowed us to provide focused treatment of the underlying artery because we can detect blood flow & location of the artery before treatment and confirm definitive endoscopic hemostasis and obliteration of the underlying arterial flow afterward by repeat Doppler examination. Our group is conducting prospective and randomized controlled studies which show promising results for the role of endoscopic Doppler in improving clinical outcomes of high risk patients with severe UGI & colon hemorrhage.” n easy...
