Asynchronus bilateral ovarian torsions in girls-systematic review.

BACKGROUND

Bilateral ovarian torsions with complete loss of ovaries is devastating. This study analyzed the literature on bilateral ovarian torsions in girls to evaluate surgical options and outcomes.

METHODS

Literature was searched on Pubmed (1987-2014) using terms "bilateral", "adnexal", "ovary", "torsion" and "children". Data were collected on age, surgical preference, pathology and outcomes.

RESULTS

Thirteen articles were identified, and 9 met the inclusion criteria (5 case reports, 4 original articles); and analyzed 17 girls (mean age: 8.75 years, range: 1-16). Bilateral oophorectomies (n=4), ipsilateral oophorectomy of severely affected ovary and contralateral oophoropexy (n=10), and detorsion of bilateral ovaries and bilateral oophoropexy (n=3) were performed. One torsion recurrence occurred after two oophoropexies. Laparoscopy and open surgery was done in 2 and 15 girls, respectively. Considering etiology, there were simple tubo-ovarian torsions (n=8), polycystic ovary (n=1), polycystic ovary associated with Down syndrome (n=1) and corpus luteum cyst (n=1). No tumors were reported. Serial ultrasound follow-ups of ipsilateral oophorectomy and contralateral oophoropexy (n=5) confirmed follicular function (n=4) and viability and position of the ovary (n=1).

CONCLUSIONS

Though extremely rare, school age girls present bilateral ovarian torsion. Ipsilateral oophorectomy and contralateral detorsion with oophoropexy has been the preferred approach.
