[Preliminary diagnostic evaluation of submucosal myoma using operative hysteroscopy]

The authors aim to underline the importance of preliminary diagnostic evaluation in the treatment of submucous leiomyoma using hysteroscopy.

The study examined 18 patients monitored at the Institute of Obstetrics and Gynecology of "La Sapienza" University of Rome between January and December 1995 in whom it was possible to make a correct definition of the lesion to be treated (number, site, size, etc.) using 3 different diagnostic methods: hysteroscopy (HS), transvaginal scan (TSV) and transvaginal echohysterography (TVHS) The authors focused attention on three different parameters: leiomyoma size, extension (intracavity/intramural portion) and evaluation of the residual leiomyoma, which are essential for optimal endoscopic resection.

HS enabled the number, size, site, origin, base, submucous portion and relations with tube operings to be evaluated, but did not allow the myometrial part of the lesion to be examined.

Integration with TSV, even if this does not allow a precise definition of the extension, highlights the size, site, involvement of myometrial structure and relations with the perimetrium, thus allowing the possibility of evaluating the residual myometrium. Compared to the above methods, TVHS highlights the effective extension (namely the submucous/intramural portion) and localization of the neoformation.
