High risk of recurrent torsion in premenarchal girls with torsion of normal adnexa

Capsule:
Recurrent adnexal torsion is more common when the first torsion episode occurs in the premenarchal period and involves otherwise normal adnexa.

Abstract:

Objective:
To compare adnexal torsion characteristics and torsion recurrence rates in a pre- and postmenarchal pediatric and adolescent population.

Design:
Retrospective cohort study.

Setting:
University-affiliated medical center.

Patient(s):
Females <18 years old with surgically diagnosed adnexal torsion. Intervention(s):
Adnexal detorsion, cystectomy, salpingectomy, or salpingo-oophorectomy by laparoscopy or laparotomy. Oophoropexy using the utero-ovarian ligament plication technique was performed in cases of recurrent torsion of normal adnexa.

Main Outcome Measure(s):
The clinical presentation, laboratory and ultrasound characteristics, surgical findings, surgical procedures, pathologic diagnosis, and torsion recurrence rates were analyzed and compared between pre- and postmenarchal patients.

Result(s):
Twenty premenarchal and 24 postmenarchal patients were identified. The clinical presentation, laboratory findings, and ultrasound characteristics were similar between the two groups, except for a higher prevalence of paraovarian cysts on preoperative ultrasound in the postmenarchal compared with in the premenarchal group (20.8% vs. 0%). For the whole cohort, torsion of normal adnexa constituted 25.0% (11/44) of cases, while torsion of “pathologic” adnexa constituted 75.0% (33/44) of torsion cases. Torsion recurrence was significantly more common among girls whose first torsion episode occurred in the premenarchal period compared with in postmenarche (35% vs. 4.2%). On multivariate logistic regression analysis, torsion recurrence was significantly associated with premenarchal status (odds ratio [OR] = 12.7; 95% confidence interval [CI], 1.1–152.0) and with torsion involving normal adnexa (OR = 19.1; 95% CI, 2.3–154.5).

Conclusion(s):
Recurrent torsion is common in patients whose first torsion episode occurred in the premenarchal period and involved otherwise normal adnexa. Ovarian fixation procedures may be considered in patients at risk for torsion recurrence.
