New uterine membrane to prevent synechiae
Zusammenfassung der Studie
The study aims to demonstrate the effectiveness of the Womed Leaf in reducing the severity of synechiae after an adhesiolysis procedure. During the study, participants will be randomly assigned to 2 groups: the first, called the intervention group, will receive the Womed Leaf device, and the second, called the control group, will follow standard care. In Switzerland, there is no standard treatment to prevent the recurrence of synechiae following an adhesiolysis, so the control group will not receive any additional treatment. Assignment to a group is done randomly, by drawing lots. In practice, at the beginning of the hysteroscopy (under general anesthesia), the surgeon will assess the extent and type of synechiae. Only patients with synechiae classified as moderate or severe are eligible for the study. If this is the case, the patient agrees to participate, and no contraindication to her participation is discovered during surgery, a draw will determine whether she receives the device or not. At the end of the operative hysteroscopy, if she is in the intervention group, the surgeon will place the Womed Leaf membrane using a small applicator in her uterus. If she is in the control group, she will not receive any device. Furthermore, the study is double-blind, so the patient will not know which group she belongs to. Participation in this trial does not change the usual follow-up of an operative hysteroscopy: the patient will therefore be invited for a control hysteroscopy 4 to 8 weeks after the intervention. The doctor will reassess her uterine cavity. On this occasion, he will also review her health status to ensure that the postoperative outcomes are satisfactory and to look for any potential side effects. One year and two years after the operation, the patient will be contacted by phone. She will be asked if she has been or is still pregnant.
