In 2007, Dr. Atallah joined Florida Hospital after completing training at Houston’s Texas Medical Center with Surgical Oncology training at MD Anderson Cancer Center. Two years to the day after completing fellowship training in colon and rectal surgery, Dr. Atallah performed the world’s first TAMIS operation (at Winter Park Hospital) on June 30, 20091. This created a new approach to treating rectal cancers and polyps, which is now being practiced in over 16 countries world-wide12. Dr. Atallah has also pioneered robotic transanal surgery3,4,10,13,14, and has been the first to describe this new technique as well. Other areas of Dr. Atallah’s research interest include understanding the tumor biology of colon cancer at the molecular level. He is the principle investigator of a major study looking at biologic tumor markers which can lead to a better understanding of cancer tumors. This study is in collaboration with Sanford & Burnham Labs and is funded by a Bankhead-Coley grant. Other than cancer surgery, and operative management of inflammatory bowel disease, his other areas of specialty include minimally invasive treatments for hemorrhoids, especially the ‘no-cutting’ operation called Transanal Hemorrhoidal Dearterialization (THD), and treatment of dysplasia. Dr. Atallah is one of the few experts in the Orlando area to perform High Resolution Anoscopy for detection and treatment of AIN (Anal Intra-epithial Neoplasia).

Dr. Atallah is world renowned for his work in rectal cancer surgery and has given several invited lectureships. In the past year, he has lectured at the European Association of Endoscopic Surgeons’ 14th World Congress in Paris, France; The Natural Orifice Surgery Consortium for Assessment and Research in Chicago; The Society of Robotic Surgeons of Orlando; The American College of Surgeons in Washington, DC and The Peking University Conference on Advanced Rectal Cancer Surgery in Beijing, China. He is scheduled in 2015 to lecture on robotic transanal surgery in Spain, Taiwan and Portugal. Dr. Atallah has also served as a panelist for the National Advisory Board for Colon Cancer Screening on the implementation of sDNA as a screening modality, and recently served as lead faculty to train surgical sub-specialists on the new techniques he has pioneered at The Center for Future Surgery, University of California, San Diego. He has authored 21 peer-reviewed publications in 2013-2014 alone, most of which focus on innovations in surgery. Last updated February, 2015.
