Office mini-hysteroscopy.

The technique of diagnostic hysteroscopy has not yet been accepted generally as an ambulatory, well-tolerated office procedure. Especially in the infertile patient the standard hysteroscopic procedure is poorly tolerated in an office environment. Our prospective registration of 530 diagnostic office mini-hysteroscopies in infertile patients demonstrates that using an atraumatic insertion technique, watery distention medium and the new generation of mini-hysteroscopic endoscopes, hysteroscopy can be performed in an office set-up without any form of anaesthesia and with a high patient compliance. The significant number of abnormal findings (28.5%), the absence of complications and the low failure rate (2.3%) indicate that diagnostic office mini-hysteroscopy should be a first-line diagnostic procedure. Those results are compared with the registration of 4204 consecutive conventional diagnostic hysteroscopies in a routine gynaecological population performed between 1982 and 1989. We conclude that the mini-hysteroscopic system offers a simple, safe and efficient diagnostic method in the office for the investigation of abnormal uterine bleeding, to evaluate the cervix and uterine cavity in the infertile patient, for screening of endometrial changes in patients under hormone replacement therapy or anti-oestrogens as (adjuvant) treatment and, lastly, it may be very helpful for the interpretation of uncertain findings in other diagnostic techniques such as ultrasound, magnetic resonance imaging, blind biopsy or hysterosalpingography.
