National trends in the surgical treatment of ovarian torsion in children: An analysis of 2041 pediatric patients utilizing the nationwide inpatient sample

Abstract

The aim of this study was to evaluate the national trends in surgical management of ovarian torsion (OT) in children. The Nationwide Inpatient Sample was queried from 1998 to 2011 for females less than 18 years of age with OT. Patients were stratified into three treatment groups: oophorectomy (OO), oophoropexy, or release of torsion (RT) alone. There were 2041 patients with OT, of which 1598 (78%) underwent OO, 126 (6%) oophoropexy, and 317 (15%) RT. RTsignificantly increased from 1998 to 2011 (9% vs 25%; P < 0.05). At nonteaching hospitals, there were higher rates of OO (89.3% vs 79.5%; P < 0.05) and lower rates of RT (10.7% vs 20.5%; P < 0.05) compared with teaching hospitals. RT was performed at a higher rate in Northeast United States compared with the South (22.7% vs 14.2%; P < 0.05). Girls presenting at nonteaching hospitals and the South had increased odds of undergoing OO compared with those presenting at teaching hospitals and the Northeast (P < 0.05). Although ovarian conservation for OTin children is more often performed in the Northeast United States and at teaching hospitals, this large population-based study demonstrates OO remains the most common surgical management for OT in the United States.
