Dr. Lee is one of the nation’s leading experts in laparoscopic and endoluminal colon and rectal surgery. Dr. Lee has published three surgical textbooks, 50 book chapters, and over 100 peer-reviewed manuscripts. He has been invited to deliver more than 200 presentations at national and international meetings.

Dr. Lee received his MD from the New York University School of Medicine, then completed his surgery residency at Beth-Israel Deaconess Hospital with Harvard Medical School. He then went onto continue his advanced training as a fellow in laparoscopic colon and rectal surgery with Jeffrey Milsom at New York Presbyterian Hospital Weill Cornell Medical Center and as a fellow in Colon and Rectal Surgery at New York Presbyterian Hospital, Columbia Presbyterian/ Weill Cornell Medical College. Dr. Lee has been board certified in colon and rectal surgery and general surgery since 2001.

Dr. Lee has pioneered a non-invasive surgical technique called CELS (combined endolaparoscopic surgery), which removes complex colon and rectal polyps not amendable for colonoscopic removal while avoiding bowel resection. Dr. Lee also developed a less invasive way to surgically treat Crohn’s and benign rectal strictures. He teaches advanced endoluminal techniques to colorectal surgical fellows twice a year as a part of his mission to bring less invasive techniques to patients across the country.

He is the lead inventor of an innovative low-cost, lightweight, wearable negative pressure, FDA approved surgical dressing called NPseal, which has been shown to reduce surgical site infections and improve wound healing.
