[Tumor asepsis in organ saving pelviscopic ovarian surgery exemplified by dermoid cysts].

Three different surgical techniques were performed to remove ovarial tumors by pelviscopic organ-preserving surgery. Contamination of the peritoneal cavity with cystic and tumorous materia had to be prevented. Ovarian surgery was done in 112 pre-menopausal patients. Three techniques were compared: 1. complete extirpation of the cyst, 2. extirpation of the cystic wall after careful irrigation of the cyst, 3. the 'diaphragm technique': the affected ovary is operated inside a bag. Contamination of the peritoneal cavity was prevented only by the 'diaphragm technique'.
