Adhesion barriers in laparoscopic myomectomy: Evidence from randomized clinical trials

Objective: To evaluate the effectiveness of different adhesion barriers in the prevention of de-novo adhesion development after laparoscopic myomectomy. Method: A systematic review was performed by searching seven electronic databases for all randomized clinical trials (RCT) comparing the use of any absorbable adhesion barrier (i.e. intervention group) with either no treatment or placebo (i.e. control group) in the prevention of adhesion development after laparoscopic myomectomy. Results: Eight RCT with a total of 748 participants (392 in the intervention group and 356 in the control group) were included. The assessed adhesion barrier methods were: the oxidized regenerated cellulose (ORC) in 2 studies, the auto-crosslinked hyaluronic acid (HA) gel in 2 studies, the 4% icodextrin solution in one study, the modified HA and carboxy-methylcellulose in one study, the polyethylene glycol ester trilysine amine solution plus a borate buffer solution in one study, and the polyethylene glycol amine plus dextran aldehyde polymers in another study. Conclusions: Adhesion barriers methods showing the most promising results were: ORC, auto-crosslinked HA gel and polyethylene glycol amine plus dextran aldehyde polymers.
