[Endoscopic therapy of cystic ovarian tumors and parovarian cysts]

108 patients with cystadenomas, 49 patients with teratomas, 17 patients with parovarial cysts and 400 patients with functional ovarian cysts were treated by endoscopic therapy from 1985 to 1989. 72 patients (42%) with cystadenomas, teratomas and parovarial cysts were operated in an organpreserving manner. Follow-up of 70 patients showed, in one case, an incompletely operated teratoma. Careful preoperative and intraoperative attention must be paid to the differential diagnosis. The difficulties and dangers of unexpected ovarian cancer are shown in two cases. The advantage of endoscopic therapy should not allow us to forget the fundamental rules of cancer surgery.
