COVARIAN : Contribution of contrast enhanced ultrasound for diagnosis of adnexal torsion: a randomized controlled trial

adnexal torsion

Percentage of surgical procedures performed in emergency (within 6 hours of arrival of the patient) without proven torsion (no visible spiral turn in intraoperative) in each group.

To meet secondary objective #1: Rate of hospitalization and rate of consultation at 1 month, pain at 7 days evaluated by a numerical scale, rate of secondary surgery with proven torsion at 1 month, rate of complications (pelvic abscess, pelviperitonitis, necrotic aspect of the ovary, non conservative treatment) at 1 month., To meet secondary objective #2: -Length of hospitalization expressed in hours or days, -Collection of intraoperative complications (during hospitalization): hemorrhage, vascular wound, digestive wound, -Collection of postoperative complications at 1 month: secondary hemorrhage, surgical resumption (whatever the reason), scar disunity, scar abscess, -Hospitalization rate and consultation rate at 1 month, -7-day pain assessed by numerical scale., To meet secondary objective #3: Incidence of serious adverse events within 30 minutes of injection of SonoVue® and collection of any delayed hypersensitivity manifestations (skin, respiratory)., To meet secondary objective #4:Quantitative and qualitative data from the process evaluation will be compared to identify and remove potential obstacles to the use of contrast ultrasound in cases of suspected adnexal torsion.
