Prevention of de-novo adhesion formation after laparoscopic myomectomy: a randomized trial to evaluate the effectiveness of an oxidized regenerated cellulose absorbable barrier

To evaluate the effectiveness of the oxidized regenerated cellulose absorbable barrier (Interceed, TC7) in the prevention of de-novo adhesion formation after laparoscopic myomectomy, a prospective and randomized study was performed at the Department of Obstetrics and Gynaecology of the University of Cagliari, Cagliari, Italy. A total of 50 pre-menopausal non-pregnant women, aged 23-42 years, who submitted to laparoscopic myomectomy from January 1993 to June 1994, were randomized to surgery alone (control group, n = 25) or surgery and oxidized regenerated cellulose barrier (Interceed group, n = 25). Neither group received any other treatment for adhesion prevention. A second-look laparoscopy was performed 12-14 weeks after laparoscopic myomectomy. The incidence of adhesion-free patients was assessed at second-look laparoscopy by an investigator not informed of the treatment. The numbers of adhesion-free patients were three out of 25 (12%) in the control group and 15 out of 25 (60%) in the treatment group (P < 0.05). In conclusion, the oxidized regenerated cellulose absorbable barrier significantly reduced de-novo adhesion formation after laparoscopic myomectomy.
