Laparoscopic Ovarian-Sparing Surgery for the Management of Benign Ovarian Lesions in Pediatric Patients: A Retrospective Analysis.

INTRODUCTION: Laparoscopic ovarian-sparing surgery (OSS) is safe and effective management approach for benign ovarian lesions in pediatric patients. This study evaluates the outcomes of females younger than 18 years who underwent the OSS procedure between December 2013 and November 2022 at a single institution. MATERIAL AND METHODS: We conducted a retrospective analysis of records from 82 females who underwent OSS for ovarian lesions. OSS was performed based on diagnostic imaging that suggested the benign nature of the lesion. RESULTS: Of the 82 patients studied, 78 had unilateral lesions and 4 had bilateral synchronous lesions. The mean age was 14 years. The majority (62 cases) of the surgeries were laparoscopic, with 20 requiring conversion to open surgery due to factors such as indistinguishable edges and large size of the lesion. We identified 8 cases of ovarian torsion. The surgical specimens revealed that 46 were ovarian teratomas, 2 were granulosa cell tumors, 15 were cystadenomas, and 23 were functional cysts. There were no intraoperative complications. Two recurrences were observed in patients who were initially treated for bilateral ovarian teratomas. One patient developed a pelvic abscess. Additionally, three patients had metachronous ovarian tumors during the follow-up period. In patients followed with ultrasound imaging, the viable ovary was visualized in 83.6% of the cases (61 out of 73). CONCLUSION: Our findings demonstrate the effectiveness of laparoscopic OSS in preserving ovarian function and providing clinical benefits in patients with benign ovarian lesions. We recommend regular follow-up with ultrasound to exclude metachronous lesions or recurrence. LEVEL OF EVIDENCE: III.
