Objective To study the operating approaches of laparoscopic resection of ovarian benign cystic teratomas. Methods 67 patients underwent operative laparoscopy for ovarian cystic teratomas(23 ovarian cystectomies,44 oophorectomies or adnexectomies),including 27 patients who had cysts more than 8cm in diameter.In operation, a plastic bag was used and the abdominal cavity was abundantly flushed with warm physiologic saline.The larger cysts were aspirated to reduce the cysts and extracted through abdominal wall incision. Results Cyst rupture occurred in 17 cases (17/44) when cystectomy was performed. No cyst spillage occurred in all the oophorectomies and adexectomies.The mean operating time was (34?19)min.Blood loss was 3ml～7ml.No complications occurred and none of the patients needed conversion from laparoscopy to laparotomy.chemical peritonitis wes not seen in any of the patiants. Conclusions Laparoscopic surgery is safe and feasible for ovarian benign cystic teratomas and allows the removal of larger ovarian cysts.
