Recurrent Ovarian Torsion: Risk Factors and Predictors for Outcome of Oophoropexy

To identify risk factors for recurrent ovarian torsion and evaluation of the efficacy of oophoropexy techniques.

Case control study.

Tertiary university-affiliated medical center.

A total of 79 women with recurrent ovarian torsion (study group) were matched with 158 women with a single episode of ovarian torsion (control group).

Laparoscopic detorsion and oophoropexy.

Demographic data, clinical characteristics, ultrasound characteristics, surgical findings, surgical procedures, and torsion recurrence rates were analyzed and compared between the 2 groups between 2001 to 2020.

There was an inverse association between women's age and the risk of recurrent torsion (adjusted odds ratio [aOR], 0.89; 95% confidence interval [CI], 0.83-0.96, p = .003). Moreover, in women younger than 20 years, the risk of recurrent event was substantially higher (aOR, 5.0; 95% CI, 1.56-6.15, p = .007). In addition, the absence of ovarian pathology was associated with increased risk for recurrent torsion (aOR, 14.3; 95% CI, 6.15-33.42; p <.001). Oophoropexy was performed in 46 women in the study group. The risk of recurrent torsion after oophoropexy was 30%. A long duration of pain before admission was associated with oophoropexy failure (37.5 ± 6.3 hours vs 11.7 ± 6.0 hours, p = .003). No single fixation procedure was superior to the others in terms of therapeutic success.

Recurrent ovarian torsion is more common in young women with a normal-appearing ovary. Oophoropexy is a safe procedure with a risk of retorsion in 30% of the patients. We found no advantage for one fixation technique over the others.
