About

Operative hysteroscopy (OH) is an endoscopic technique for the treatment of benign intrauterine lesions and in particular uterine fibroids. The limit of this technique is the duration of the operation which is correlated with the operative risks. Thus, when there is a large fibroid or several fibroids, this technique can sometimes not be used or require several sessions. Today there is a new technique of HO that theoretically allows a gain in operative time. There are few comparative studies showing a clinically interesting gain in operating time. The aim of this study is to compare the operative time between the classical HO technique by resection and the vaporization technique.

This is a randomized, single-center study. The study population corresponded to women aged over 18 years requiring operative hysteroscopy for fibroids. After obtaining informed consent, patients will be randomized into two groups: a vaporization hysteroscopy group and a resection hysteroscopy group. The primary endpoint will be operative time. The secondary endpoints will be intraoperative characteristics and complications (amount of distension fluid used, cervical injury, uterine perforation), immediate postoperative data (pain) and medium-term data (postoperative synechiae). The starting hypothesis is that the technique of hysteroscopy by vaporization would reduce the operative time by 30%. The number of subjects required per group will be 27 patients, or 54 patients in total over 24 months.

The expected results are a significant decrease in operative time with the vaporization hysteroscopy technique. This would be important because the reduction in operative time is associated with a reduction in complications of operative hysteroscopy and the possibility of treating larger fibroids with this technique.
