Nowadays operative hysteroscopy represents the elective treatment of submucous and partially intramural fibroids. Seventy patients underwent hysteroscopic resection of fibroids, because of abnormal uterine bleeding in 58 (82.8%) cases, and infertility in 12 (17.2%) cases. The evaluation of the lesion was performed by diagnostic hysteroscopy and abdominal (57 patients) or transvaginal (13 patients) ultrasounds. In particular, for the evaluation of the intramural portion of the lesion, the hysteroscopic study of the angle between fibroid and myometrium was fundamental: the more acute the angle is the more intracavitary the myoma is. Forty-six (65.7%) out of 70 had a completely intracavitary fibroid; in 14 (20%) cases the intramural development was less than 1.5 cm and in the remaining 10 (14.3%) cases was more than 1.5 cm. Integration of hysteroscopy and ultrasounds for the assessment of myomas and the preoperative preparation by LH-RH analogues allow to perform an endoscopic resection of myomas which has up to, and sometimes over, 50% of their volume in the uterine wall.
