Abstrakt: Background: Isolated fallopian tube torsion (IFTT) is a rare form of adnexal torsion that is more difficult to diagnose, which may lead to delays in treatment. Our objectives were to identify clinical and radiologic factors associated with surgically-confirmed IFTT and compare them with those of patients without torsion and with adnexal torsion (AT) in a large pediatric population.
Methods: We conducted a retrospective chart review of all patients who underwent surgery for suspected adnexal torsion from 2016 to 2019. Torsion was determined intraoperatively, with IFFT defined as those with only tubal but no ovarian torsion and AT defined as those with ovarian torsion, with or without involvement of the ipsilateral fallopian tube. Clinical and radiologic variables were compared between patients with IFTT and those without torsion and with AT using descriptive statistics. A previously-described composite score to predict torsion based on the presence of vomiting and adnexal volume (VVCS) was calculated for each patient.
Results: Of 291 patients who underwent surgery for suspected torsion, 168 had confirmed torsion: 33 (19.6%) IFTT and 135 (80.4%) AT. Patients with IFTT were more likely to be younger (12.8 vs. 14.2 years, P = 0.02), premenarchal (29.0% vs. 10.7%, P = 0.009), experience nausea (90.6% vs. 70.9%, P = 0.02) and vomiting (81.3% vs. 32.8%, P < 0.001), have a paratubal cyst on imaging (18.8% vs. 2.5%, P = 0.003), and have larger adnexal volume (143.3 vs. 64.9 ml, P < 0.001) than those without torsion. Higher BMI (26.6 vs. 22.9 kg/m2, P = 0.03), a paratubal cyst on imaging (18.8% vs. 1.5%, P < 0.001), presence of arterial (65.5% vs. 44.1%, P = 0.04) and venous Doppler flow (79.3% vs. 55.9%, P = 0.02), and radiologic impression indicating lack of torsion (37.9% vs. 16.8%, P = 0.04) were more common in IFTT than AT. The accuracy of the VVCS in predicting torsion for the IFFT group was 83.9%.
Conclusions: IFTT has a similar clinical presentation to AT but with a higher likelihood of a paratubal cyst and preserved Doppler flow on imaging. IFTT should be strongly considered in patients who present with pain, nausea, and vomiting and have an adnexal mass separate from the ovary on imaging, regardless of Doppler flow.
