We aimed at studying isolated Fallopian tube torsion (IFTT) in a relatively large cohort of women and to evaluate different features of IFTT in comparison to a large cohort of women with non-IFTT adnexal torsion (NIAT). This was a retrospective cohort study. We included women with surgically confirmed ovarian and/or Fallopian tube torsion between March 2011 and June 2020. Fifty-four cases of IFTT were surgically confirmed during the study period and were compared to 422 surgically confirmed NIAT. The rate of controlled ovarian hyperstimulation treatments, current pregnancy, and vomiting was lower in the IFTT group compared with the NIAT group. Cervical tenderness and vaginal discharge were more common in the IFTT group. Oedematous and enlarged ovaries were less common in the IFTT group. In multivariate regression analysis, the following factors were independently associated with IFTT: (i) vaginal discharge [adjusted odds ratio (aOR) 95% CI 8.16, 1.98–33.55]; (ii) cervical motion tenderness (aOR 95% CI 2.71, 1.01–7.29); (iii) fertility treatments (aOR 95% CI 0.26, 0.70–0.77); (iv) previous abdominal surgery (aOR 95% CI 0.46, 0.22–0.96); (v) vomiting (aOR 95% CI 0.38, 0.19–0.76); and (vi) enlarged ovary (aOR 95% CI 0.34, 0.18–0.65). In conclusion, we have identified factors positively and negatively associated with IFTT in a large cohort of women with adnexal torsion.
