Hyalobarrier is a substance to keep tissue apart post surgery and therefore prevent adhesions. It contains autocross-linked hyaluronan. Highly viscous due to condensation. Hyaluronan is present in cartilage and skin hence there is a natural metabolic pathway for it. This gel is used to separate organs and tissue after surgery. Scientific documentation so far covers the gynaecology speciality. IE Laparoscopic surgery, hysteroscopy/hysteroscopic surgery but also open surgery. According to data in a Cochrane collaboration review active action to prevent adhesions needs to be taken to a larger extent. The Cochrane report also states that the incidence of postsurgical adhesions is as high as 60 to 90%.[1] In a recent review by C Sutton (University of Surrey, Guilford UK), it is stated that Hyalobarrier is the only anti adhesive substance that has published data for intrauterine use.[2]
