Dr. Neuwirth is a pioneer of gynecologic endoscopy, which employs a telescope to look into the body, avoiding large incisions during surgery. He was chairman of the Department of Obstetrics and Gynecology at St. Luke’s-Roosevelt from 1974 until 1991, and from 1977-2000 was the first Babcock Professor of Obstetrics and Gynecology at Columbia University. He served as an examiner for the American Board of Obstetrics and Gynecology from 1982-1998. Dr. Neuwirth introduced laparoscopy in the US in 1968, with research articles on laparoscopic sterilization and ovarian biopsies. In 1969, he introduced hysteroscopy-- the use of a telescope to look into the uterus--and authored a monograph on the technique in 1974. In 1976, he developed resectoscopic surgery of submucous fibroids. In 1992, Dr. Neuwirth authored the first report on long-term outcome of menstrual function following hysteroscopic endometrial ablation, a treatment for abnormal uterine bleeding. He is also the inventor of balloon endometrial ablation. At this time, he is doing a follow-up study in ablation patients to determine the subsequent incidence of carcinoma, as well as investigating other methods of nonhysteroscopic endometrial ablation to avoid hysterectomy.
