Introduction: Ovarian sparing surgery (OSS) is the recommended treatment for benign pediatric ovarian masses in order to optimize future fertility.  We evaluated the outcomes of pediatric patients after OSS for non-neoplastic and benign neoplastic ovarian lesions.

Methods:   A retrospective review was performed on children under 18 years of age who underwent ovarian sparing surgery for benign ovarian lesions from 2003-2012.  Data collected included demographics, operative details, post operative course, and subsequent surgical intervention. Post-operative menstruation was documented as a potential indicator of intact ovarian function. 

Results: One hundred and nine patients underwent OSS with a median age of 13.4 years (IQR 11.4 -15.1 years). Eighty-two patients were treated laparoscopically with 4 conversions to open. Twenty-seven had open procedures.  Postoperative complication of surgical site infection occurred in 7 patients (6%).  Pathology most commonly revealed functional ovarian cysts (n=57) and mature teratomas (n=37).  Ninety-two patients (84%) were followed for a median of 10.6 months (IQR 0.72 -30.8 months).  Fifty-five patients (60%) had subsequent imaging surveillance a median of 7.3 months postoperatively (IQR 3.9 -13 months).  Twenty-one patients (38%) developed a second lesion within a median time of 11 months (IQR 7.7 -24 months).  This rate was not significantly different for the benign neoplastic compared to the non-neoplastic lesions (28% vs. 47%, p = 0.15).  Nine patients (10%) underwent reoperation for mass enlargement or persistent abdominal pain within a median time of 12.2 months (IQR 8.2 -44.5 months).   Fifty-eight (63%) patients had begun or resumed menses at their most recent follow up.  Three patients were able to conceive after OSS with a median lapse time of 5 years (range 2.4-6.7 years).

Conclusion: Benign ovarian lesions in children can be treated successfully with ovarian sparing surgery with low recurrence and reoperation rates while preserving ovarian function in the majority of patients.  Longer follow-up is needed to determine the utility of menstruation as a predictor of fertility.
