ABSTRACT
STUDY OBJECTIVE: Isolated tubal torsion (ITT) is a surgical emergency that is less well characterized than ovarian torsion and presents with its own diagnostic challenges. We retrospectively examined patients with ITT and compared them to patients with ovarian torsion to better understand the unique features of this pathophysiologic process.
METHODS: The medical records of patients who were identified as having ITT or ovarian torsion intraoperatively between January 2019 and November 2022 were reviewed. Patient demographics, clinical documentation, diagnostic imaging reports, operative reports, and pathology results were collected.
RESULTS: A total of 82 patients met inclusion criteria of which 62 (75.6%) had ovarian torsion and 20 (24.4%) had ITT. Most patients (63.4%) underwent 2 or more imaging studies prior to the operating room. A diagnosis of torsion occurred more often on preoperative imaging for the ovarian torsion group (67.7% ovarian torsion vs 35.0% ITT, p=0.01). Doppler flow to the ovary was expectedly absent in 65.9% of ovarian torsion patients but interestingly also absent in 25% of ITT patients (p=0.01). Patients with ovarian torsion were more likely to have ovarian cysts (56.5% vs 10.0%, p<0.001), while patients with ITT were significantly more likely to have a paratubal cyst (90.0% vs 38.7%, p<0.001).
CONCLUSION: ITT is a surgical emergency that poses a risk to future fertility. Ultrasound studies, including doppler, may not be as definitive in patients with ITT and early cross-sectional imaging should be considered. When there is a high clinical suspicion for ovarian torsion or ITT, there should be a low threshold for diagnostic laparoscopy.
