Dr. Atallah on developing ‘TAMIS'

TAMIS is a revolutionary approach to the removal of rectal tumors and polyps that I co-developed in 2009.  It has quickly caught on -- this technique is now being performed at top institutions worldwide.  More importantly, it has lead to the next-step in avanced rectal cancer surgery, whereby tumors of the rectum can be removed with less scars, better outcomes, and probably with fewer patients winding up with a permanent ostomy.  This is GREAT NEWS for patients battling this curable disease! … TAMIS is simply an innovation that makes all the sense in the world.
