Recommendations for Postoperative Surveillance of Pediatric Benign Ovarian Neoplasms.

STUDY OBJECTIVE: To assess postoperative management of pediatric patients with benign ovarian neoplasms, to develop recommendations for postoperative care. DESIGN: A retrospective cohort study. SETTING: Eight pediatric hospitals in the midwestern United States. PARTICIPANTS: Patients up to 21 years of age who underwent surgery for a benign ovarian neoplasm between January 2010 and December 2016 were included. INTERVENTIONS: No prospective interventions were evaluated. MAIN OUTCOME MEASURES: Main outcome measures included postoperative imaging findings, recurrence rates, reoperation rates, and the timing of the aforementioned results. RESULTS: A total of 427 patients met inclusion criteria. After the index surgery, 155 patients (36%) underwent a routine imaging study. Among those with routine imaging, abnormalities were noted in 48 patients (31%); 7 went on to have reoperation (5%), and no malignant pathologies or torsion were identified. Excluding the 7 patients who went on to have a reoperation as a result of routine imaging, 113 patients developed symptoms postoperatively and underwent imaging as a result (27%, 113/420). Abnormalities were noted in 44 (10%); 15 of these patients underwent reoperation (4%), among them 2 with malignancies and 3 with torsion. Of these 44 patients, 23 had initially undergone routine imaging and subsequently went on to have symptomatic imaging, with 17% (4/23) undergoing reoperation. CONCLUSIONS: Routine imaging did not identify malignancy; most lesions identified on routine imaging were incidental findings. Although the study was not powered to appreciate a statistically significant difference, patients with malignancy or torsion were identified in the symptomatic group. This suggests no benefit from routine imaging, and supports symptomatic imaging postoperatively to minimize costs and patient/family burden.
