[Pelviscopic ovarian surgery--a retrospective study of 1,016 operated cysts].

In 969 patients, we observed 1016 ovarian cysts at pelviscopy between the years 1984-89. 36 of these were non-benign. On the basis of the pre- and intraoperative findings (palpation, sonography, inspection of the cyst surface under eye-glass magnification) we treated 827 cysts exclusively by pelviscopy, 189 cysts by laparotomy. Laparotomy was preceded by pelviscopic surgery on the cyst in 94 cases. None of the pre- and intraoperative findings completely eliminated the risk of performing pelviscopic surgery on a stage Ia carcinoma; indeed, this occurred in 2% (2/1016).
