Reduction of Adhesion Reformation After Laparoscopic Endometriosis Surgery: A Randomized Trial With an Oxidized Regenerated Cellulose Absorbable Barrier

Abstract

To evaluate the effectiveness of an oxidized regenerated cellulose absorbable barrier (Interceed [TC7] Absorbable Adhesion Barrier) in the reduction of adhesion reformation after laparoscopic surgery for endometriosis. Thirty-two premenopausal nonpregnant women who had severe endometriosis and complete posterior cul-de-sac obliteration and were undergoing laparoscopic surgery were randomly assigned to either surgery alone or surgery and Interceed. None of the subjects received any other treatment for adhesion prevention. Second-look laparoscopy was performed 12-14 weeks after laparoscopic surgery by an investigator blinded to the treatment, and the incidence of adhesion-free subjects was assessed. Twelve of 16 (75%) women treated with the oxidized regenerated cellulose barrier were free of adhesions, compared with two of 16 (12.5%) controls, a statistically significant difference (P < .05). The oxidized regenerated cellulose absorbable barrier significantly reduces adhesion reformation after laparoscopic surgery for endometriosis.
