Dr. Sam Atallah, MD FASCRS, FACS

Director of Research & Clinical Trials

Colon and Rectal Surgeon

Dr. Atallah is among the most well known colorectal surgeons in the world. He moved to Orlando in 2007 after completing training at Houston's Texas Medical Center with Surgical Oncology training at MD Anderson Cancer Center where his training had earned him double-board certification in General Surgery and Colorectal Surgery. Two years to the day after completing fellowship training in colon & rectal surgery, Dr. Atallah performed the world's first TAMIS operation in Winter Park, FL on June 30, 2009. This created a new approach to treating rectal cancers and polyps, that is now being practiced in more than 50 countries. Dr. Atallah pioneered robotic transanal surgery and was the first in the world to perform this technique. He is one of the leaders in advanced technology for rectal cancer surgery and has developed the technique of stereotactic navigation for transanal total mesorectal excision (taTME) -- an important step forward in the evolution of computer-assisted surgery. Complex treatment of rectal cancer and surgical management of this disease through the new techniques of TAMIS and taTME represent Dr. Atallah's principal interests in colorctal surgery; and he is currently producing a textbook on these topics scheduled for 2019 publication by Springer Nature. He is also actively involved in the design and assessment of next-generation robotic systems that will be smaller, sleeker, and able to work in places and spaces never before imagined.
