hyalobarrier hyalobarrier 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 barrier agents may be a little more effective in preventing adhesions than no intervention. the cochrane report also states that the incidence of postsurgical adhesions is as high as 50 to 100%. 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. additional information laparoscopy asherman's syndrome
