Dr. Alex Jenny Ky is a Professor of Surgery at The Mount Sinai Hospital in New York.  A graduate of Brown University and SUNY Stony Brook School of Medicine, Dr. Ky completed a General Surgery residency at Lenox Hill Hospital and a Colon and Rectal Surgery fellowship at Mount Sinai School of Medicine. 

Dr. Ky is an expert in laparoscopic colon and rectal surgery, performing complex procedures that few other doctors in the world are able to perform. She is the first person in New York City to use a sacral nerve stimulator and one of the few people in New York City treating fecal incontinence with the use of an artificial anal sphincter.  Dr. Ky is specially trained in transanal endoscopic microsurgery (TEM), a new technique which allows some rectal tumors low in the rectum to be removed through the anus, possibly avoiding the need for a permanent stoma and abdominal surgery.  She also specializes in stapled transanal rectal resection (STARR) and the procedure for prolapse and hemorrhoids (PPH). 

Dr. Ky was appointed as the Medical Director of our Chinatown practice and she oversees a multidisciplinary healthcare practice providing expert medical care and building a presence for Mount Sinai in Chinatown.  Providing the highest quality of care to the community is Dr. Ky’s top priority.

Dr. Ky is also a member of the American Society of Colon and Rectal Surgeons, Chinese American Medical Society, and the Chinese American Independent Practice Association, to name a few. She is also fluent in Cantonese and Mandarin.
