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

Abstract

Study Objective: The study aimed to evaluate whether there is an association between the ovarian ligament length and ovarian torsion. Design: This is a prospective cohort study. Design Classification: II.2. Setting: The study was conducted in the gynecology department of a university affiliated hospital. Intervention: We measured the length of the ovarian ligaments during laparoscopy. Patients: 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). Measurement and Main Results: 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). Conclusion: 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.

Ovarian size as a risk factor for recurrent adnexal torsion: Smaller is not better

“…In a prospective cohort study, Tamir et al . found a correlation between longer ovarian ligament length and ovarian torsion . The correlation between AT and longer ovarian ligament is an independent risk factor, unrelated to the presence of ovarian mass.…”

Adnexal torsion recurrence—is the adnexal twist degree a risk factor? A retrospective cohort study

“…A possible physiological explanation for the association of twist degree to recurrence risk might be the degree of freedom of the adnexa after de‐torsion. Tamir Yaniv et al 17 . found correlations between ovarian ligament length and adnexal torsion.…”

“…Attempts of minimising inaccuracies were made by manual validation of individual medical files and by the preliminary exclusion of patients with missing or incomplete data. We lack data regarding ovarian ligament length and Fallopian tube length, a possible risk factor for adnexal torsion, 17 as this is not regularly recorded in our department. Furthermore, our study includes only women with an operatively diagnosed adnexal torsion.…”

Ovarian Ligament Plication as a Treatment for Patient with Elongated Ovarian Ligament with Recurrent Abdominal Pain in the Absence of Ovarian Torsion

“…The normal length of the right ovarian ligament is 2.2 ± 0.6 cm, whereas the length of the left ovarian ligament is 2.3 ± 0.8 cm. [ 9 ] Tamir Yaniv et al . [ 9 ] found a correlation between increased ovarian ligament length and ovarian torsion, which is the basis of ovarian ligament plication or oophoropexy in cases of ovarian torsion.…”

“…[ 9 ] Tamir Yaniv et al . [ 9 ] found a correlation between increased ovarian ligament length and ovarian torsion, which is the basis of ovarian ligament plication or oophoropexy in cases of ovarian torsion. Chances of recurrence of torsion are higher if earlier torsion had occurred in the absence of adnexal mass.…”
