Purpose: This study aims to investigate the values of laparoscopic surgery in treating ovarian tumors in children. Materials and Methods: A total of 51 pediatric patients with ovarian tumors were enrolled, and all the patients were treated using laparoscopic surgery, including 48 cases of ovarian tumorectomy for benign tumors and three cases of unilateral adnexectomy for prophase germinoma; the operation time, average postoperative hospital stay, tumor recurrence, and growth and development of the patients were followed up. Results: All the patients were successfully underwent laparoscopic surgery, among which six cases had an ovarian cyst pedicle torsion, but with restored good ovarian blood supply. The mean operation time was 40 ± 15 minutes, and the average postoperative hospital stay was 3 ± 1 days. Follow-up was performed for si months to seven years, and the three cases of prophase germinoma were followed up for two to five years; no evidence of tumor recurrence was observed, and no growth abnormality occurred. Conclusions: Laparoscopic surgery for ovarian tumors in children has less damages, rapid postoperative recovery, and fewer complications, therefore it is safe and effective.
