Normal ovarian tissue surrounding mature teratomas: ultrasonographic-surgical correlation

Study ObjectiveTo establish the importance of ultrasound visualization normal ovarian tissue in predicting preservation ovary with mature teratoma. The poor results from teratomas were published articles 2022. (1,2,3)DesignA prospective longitudinal study using data all surgically treated patients twisted and non-twisted January 2006. through November 2022 one surgical team. Informed consent was obtained their parents.Participants109 aged under 19 years old. mean age 14 years.Main Outcome MeasuresRate teratoma relative to collected ultrasonographic such as presence or crescent sign (OCS), volume, features suggestive teratomas. diagnostic accuracy OCS assessed confidence interval (C.I.).ResultsMedian volume 235 ml (range 45 1200 ml) reported 94 uncomplicated by torsion, including 3 girls bilateral Ovaries successfully preserved them (100%). edema surrounding tumor 15 complicated torsion affected 9 (60%). visualized transabdominal probe 89 (95% [C.I.]: 90-99). After difficulties five girls, transrectal sonography them.A presumed preoperative diagnosis based on signs 99 (91%) patients. Laparoscopy performed 84 laparotomy approach 25 whose greater than 500 tumor's large dominant solid parts seen ultrasound. During follow-up, formation a new same contralateral occurred six patients.ConclusionsThe shows that tissue, which can be stretched thinned growing tumor, is ultrasonography finding most important predictor successful ovaries, regardless approach, has evaluation young adnexal masses.
