Correlation between the Length of Ovarian Ligament and Ovarian Torsion: A Prospective Study.

The study aimed to evaluate whether there is an association between the ovarian ligament length and ovarian torsion. This is a prospective cohort study. Design Classification: II.2. The study was conducted in the gynecology department of a university affiliated hospital. We measured the length of the ovarian ligaments during laparoscopy. A total of 56 women were recruited, of which 28 women were operated for ovarian torsion (torsion group) and 28 others for other gynecologic conditions (control group). The study found correlations between ovarian ligament length and ovarian torsion. The length of the right (2.2 ± 0.6 cm) and left ovarian ligament (2.3 ± 0.8 cm) in the control patients were similar. Ovarian torsions occurred mainly on the right side (67.9 %). The right ovarian ligament was significantly longer in the torsion group (3.2 ± 0.9 cm) than in the control group (2.2 ± 0.6 cm; p < 0.001). Even after exclusion of patients with ovarian cyst, the ovarian ligament was still significantly longer in the torsion group as compared to the control group (3.2 ± 1.1 vs. 2.2 ± 0.6 cm respectively, p = 0.01). Our results suggest that increased length of ovarian ligament might be correlated with the development of ovarian torsion. This could be a basis for ovarian ligament fixation or oophoropexy at the time of conservative surgery for ovarian torsion.
