CHICAGO -- The exact state of the uterus 1 year after global endometrial ablation with Nova-Sure is largely unknown, but certain characteristics are beginning to emerge, Robert Sabbah, M.D., reported at the annual meeting of the AAGL.
Even though global endometrial ablation is becoming increasingly common, radiologists are hard-pressed to describe their findings as there are no data available to allow adequate correlation between ultrasound images, hysteroscopic images, and uterine cavity endometrial sampling.
In addition, there are no clear treatment guidelines for women who have continuous bleeding after global endometrial ablation, he said.
One of the first rules to emerge is that abnormal bleeding after endometrial ablation should always be investigated first with transvaginal rather than transab-dominal ultrasound, said Dr. Sabbah, director of obstetrics and gynecology at Sacred Heart Hospital and professor of obstetrics and gynecology at the University of Montreal.
Transabdominal ultrasound does not properly identify normal endometrial thickening or echogenicity.
Secondly, irregular slight thickening of the endometrial stripe can be simply islets of residual tissue in the cavity.
Dr. Sabbah came to these conclusions based on an ongoing prospective study in which the uteri of 45 women were evaluated with both transvaginal and transabdominal ultrasound 1 year after NovaSure (Cytyc Corp., Palo Alto, Calif.) endometrial ablation. In select cases, the women went on to hysteroscopy or were evaluated with magnetic resonance imaging if the ultrasound appearance of ...
