Ovarian Preservation and Recurrent Torsion in Children: Both Less Common Than We Thought.

Purpose: Surgical management of pediatric ovarian torsion includes total oophorectomy (TO) or ovarian preservation surgery (OPS). This study sought to identify factors contributing to surgical management and readmission outcomes for ovarian torsion.

Methods: The Nationwide Readmission Database from 2010-2014 was used to identify patients < 18 years admitted with ovarian torsion. Patient factors, hospital characteristics, and readmission outcomes were compared by TO and OPS. Standard statistical analysis was performed and results were weighted for national estimates.

Results: There were 6028 patients (age 13 ± 4 years) identified with ovarian torsion who underwent either TO (50%) or OPS (50%). Patients had secondary pathology of ovarian cyst (41%), benign mass (19%), and malignant mass (0.4%). OPS was more common in teaching hospitals (84% vs. 74% TO, P<0.001), patients < 13 years of age (41% vs. 37% TO, P = 0.001), and those from high-income households (51% vs. 41% TO, P<0.001). The overall readmission rate was 4%, with no difference between surgical approach (4.3% OPS vs. 4.4% TO, P = 0.882). Of those readmitted (n = 265), readmission diagnoses were cyst (10%), malignant mass (9%), benign mass (7%), and torsion (5%). The overall rate of recurrent torsion was 0.2%, with no difference between OPS and TO (< 0.3% vs. < 0.2%, P = 0.282).

Conclusion: Half of pediatric patients are undergoing TO for ovarian torsion in the U.S. and disparities exist with the utilization of OPS. There is no difference in rate of readmission or recurrent torsion between surgical approaches, and the overall rate of retorsion is lower than previously reported.
