Management of Adnexal Torsion in the Pediatric and Adolescent Population at Western Australia's Single Tertiary Children's Hospital over the Last 10 Years: Retrospective Study

Abstract

To review our institutional data regarding the management of adnexal torsion (AT) and assess the ovarian conservation rates. Retrospective study. Tertiary children's hospital. Pediatric and adolescent patients with surgically diagnosed AT. Participants (n = 54, mean age 9.80 ± 3.95 years) were identified between June 2010 and May 2019. Surgical management of AT. The primary outcome was to determine the ovarian conservation rates in AT cases. The secondary outcomes were to determine the incidence of AT to total emergency department (ED) presentations, decision to operation theater (OT) time in AT cases, return to OT, histopathology, and follow-up with ultrasound to determine ovarian function. Data were collected on demographic and clinical characteristics. Continuous data were compared with t tests or Kruskal-Wallis tests; categoric data were compared with chi-square tests. A total of 52 (96.29%) patients had ovarian conservation, and 53 (98.14%) had laparoscopic management. The incidence rate for AT cases to total ED presentations for the last 10 years was 9.9 per 100 000, which was based on a Poisson distribution. Presentations to an ED for AT cases have trended upward since 2010. Decision to OT time was statistically significantly shorter in cases with preoperative suspicion of AT than those with intraoperative diagnosis of AT (p = .000). A total of 7 (12.96%) patients returned to OT for suspicion of recurrent torsion. Of these, 5 (9.26%) had confirmed repeat AT. The presence of fever, pain duration, severity of pain, and severity of torsion did not correlate with the follow-up ultrasound findings of ovarian activity. The findings from our study suggest that high ovarian conservation rates are achievable in AT cases. A high index of suspicion is required to prevent a delay in surgery.
