title: [Evaluation of different technics of uterine evacuation as a risk factor for invasive and metastatic trophoblastic neoplasms].
abstract: A study was conducted to determine the effect of the form of uterine evacuation (curettage or vacuum aspiration) and of the use of oxytocin on the incidence of invasive/metastatic gestational trophoblastic neoplasia among patients with a diagnosis of molar abortion. The study was conducted on 42 patients with a histopathological diagnosis of benign complete hydatidiform mole and with a uterine height of more than 12cm. Twenty-five patients were submitted to uterine evacuation by curettage and 17 to uterine evacuation by vacuum aspiration. Twenty-seven of the same 42 patients received oxytocin to promote dilation of the cervix and/or partial mole expulsion, and 15 were not treated with this drug. Statistical analysis showed that the use of oxytocin before uterine evacuation was a factor contributing to a higher risk of development of invasive neoplasia, especially when associated with curettage of the uterus.
