Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess the safety and effectiveness of PROTAHERE Absorbable Adhesion Barrier to prevent pelvic postoperative adhesions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is a random, evaluator-blinded, controlled, single center clinical trial. Recruiting patients who are premenopausal and scheduled for pelvic surgery including myomectomy, pelvic adhenolysis, endometriosis surgery, salpingostomy, dermoid cyst removal, ovarian cystectomy or any pelvic surgery other than total metrectomy. Patients recruited are randomly divided into five groups, PROTAHERE, Hyalobarrier, Seprafilm, Interceed or no treatment when the inclusion criteria are met and the inform consents are obtained. They are followed for 24 months including visits at 14 days, 3, 6, 12, 18, 24 months post-operation for the safety and effectiveness evaluation. The primary endpoints are the incidence of adhesions at 3-month as well as the incidence of any adverse events during the study.
