Clinical and pathological comparisons of adnexal torsion between pregnant and non-pregnant women

Abstract

AIM: We evaluated and compared the clinical and pathological differences between pregnant and non-pregnant women with adnexal torsion.

METHODS: We retrospectively reviewed 239 women with adnexal torsion from January 2006 to December 2015 in a tertiary hospital. The clinical and pathological differences between pregnant and non-pregnant women who underwent surgery for adnexal torsion were analyzed.

RESULTS: The most common pathologies were corpus luteum cysts in pregnant women and dermoid cysts in non-pregnant women. Eight of the pregnant women (24.2%) had a history of exogenous ovarian stimulation, and their episodes were only caused by corpus luteum or a stimulated ovary. In pregnant women, 72.7% of the torsion occurred before the 14th week of gestation.

CONCLUSION: The common pathology causing adnexal torsion was different, depending on the pregnancy status. Exogenous ovarian stimulation increases the risk of adnexal torsion, and the majority of episodes occurred in the first trimester in pregnant women.
