Recurrent torsion of otherwise normal adnexa: oophoropexy does not prevent recurrence

Recurrence of adnexal torsion involving otherwise normal adnexa is not rare. Various oophoropexy (ovarian fixation) procedures have been suggested to prevent recurrence; however, long-term information of their efficacy is lacking. The aim of this study was to investigate the recurrence rate of adnexal torsion following oophoropexy.

Retrospective cohort study, including all consecutive patients who underwent an oophoropexy procedure for the prevention of recurrent torsion of "normal adnexa" in our department from 2008 to 2019 by shortening of the utero-ovarian ligament.

Nineteen patients (age range 7-35 years) with a mean follow-up of 90.9 ± 57.7 months were identified. Fifteen of them (78.9%) were re-operated for recurrent torsion following an oophoropexy procedure, while four (21.1%) did not experience recurrence. Nine torsion recurrences following an oophoropexy occurred within the first 2 postoperative years. There were no differences in mean age and menarcheal status )pre- or post-menarcheal) at the time of the first torsion event, age at the time of oophoropexy, oophoropexy side, number of adnexal torsion events before oophoropexy, and follow-up duration between those with and those without post-oophoropexy recurrences.

Oophoropexy procedure by shortening of the utero-ovarian ligament may not prevent recurrent torsion of otherwise normal adnexa. Further studies to determine whether combined fixation (utero-ovarian and round ligament plication) is more efficacious than isolated utero-ovarian plication for the prevention of recurrent torsion are warranted.
