Asynchronous bilateral ovarian torsion.

Background: Pediatric ovarian torsion (OT) is a serious condition, especially in cases of asynchronous bilateral ovarian torsion (ABOT). The authors sought to evaluate the predisposing factors for ABOT and to evaluate the most appropriate treatment for ovarian torsion.

Methods: The authors retrospectively reviewed the charts of patients with ovarian torsion between 1980 and 2002. Data collected included age at presentation, type and duration of symptoms, ultrasound scan findings, interval to surgery, procedures, pathology report, and follow-up.

Results: Seventy-six patients had adnexal torsion confirmed at surgery, 4 of whom had ABOT. The mean age was 10 years. The mean duration of complaints before hospitalisation and interval to surgery were 56 and 33 hours, respectively. Thirty-five patients had simple tubo-ovarian torsion (46%), including all the patients with ABOT (11.4%), and 41 had an ovarian pathology (54%). All patients with ABOT underwent salpingo-oophorectomy at the first episode. They presented earlier for the second episode and had a shorter interval to surgery where detorsion with oophoropexy was performed. Follow-up ultrasound scan showed perfusion and follicles in the remaining ovary.

Conclusions: The diagnosis of ovarian torsion often is delayed, especially when a solid tumor is suspected. Conservative management should be strongly considered when there is no underlying ovarian pathology. Furthermore, oophoropexy of the ipsilateral and contralateral ovary should be considered to prevent a potentially devastating recurrence.
