Laparoscopy for Ovary-Sparing Tumorectomy in Children with Ovarian Tumors: A Clinical Retrospective Analysis.

The aim of this study is to analyze the characteristics of pediatric ovarian tumors (OTs) and evaluate treatment strategies for ovary-sparing tumorectomy (OST). Medical records of children from October 2011 to December 2021 were reviewed. Data regarding clinical characteristics, pathological type, and management of OST were analyzed. In total, 61 patients with OTs were screened. The median age was 14.8 ± 3.0 years. The median length and volume of borderline and malignant OTs were larger than those of benign OTs ( < .001 and  = .05, respectively). There was a significant difference in the median OT volume between torsion and nontorsion OTs ( = .04). The overall OST rate was 91.8% (67/73). A total of 53.4% (39/73) lesions were treated with laparoscopic OST. The OT volume was smaller in patients who underwent laparoscopy than in those who underwent laparotomy ( = .04). The probability of intraoperative tumor rupture or spillage was higher during laparoscopy than during laparotomy ( = .02). No significant differences were observed in OT recurrence. Seven patients had borderline and malignant tumors, 3 of whom had stage IA tumors and underwent OST. None of the patients experienced relapse. OT size is a useful reference factor for differential diagnosis and choosing laparoscopic surgery. Intraoperative tumor rupture and spillage of benign tumors during laparoscopy and laparotomy did not seem to be associated with recurrence, and laparoscopic OST was considered safe. Further prospective studies are required to confirm these conclusions.
