[Hysteroscopy in menopause: analysis of the techniques and accuracy of the method].

Detection of endometrial cancer in asymptomatic women has not proved to be a cost-effective procedure. Studies on this matter have shown that ultrasonography as a detecting method presents a high ratio of false-positive results and a negligible effect on the mortality rate. This way, the assistance strategy should be based on earlier diagnosis and appropriate treatment in women who present postmenopause bleeding. Being a non-invasive method, largely available and with high sensitivity, the transvaginal ultrasonography should be the initial investigative method. Though there is no consensus about the echographical endometrial thickness, above which the investigation is to proceed, diagnostic hysteroscopy should be the next step. The risk of neoplasia in endometriums with thickness under or equal to 3 mm is low enough to limit hysteroscopy to exceptional cases. Biopsy must be a necessary part of the hysteroscopy, because the diagnosis, made on visual basis, alone may lead to false results. Outpatient hysteroscopy can be done in more than 95% of the cases, even in menopausal women, rarely with severe complications. The adoption of "non-contact" examination techniques and the progressive reduction of the hysteroscope diameter have decreased the discomfort associated to small outpatient procedures.
