Abstract:Postoperative intra-abdominal adhesions are associated with significant morbidity and mortality. In this study, the effect of topical fibrin glue (FG) on adhesion formation in a rat model was investigated. Forty Sprague-Dawley male rats underwent midline laparotomy. Bilateral peritoneal-muscular abdominal wall defects were created and then replaced with premeasured soft tissue Goretex patches. Rats were randomized to FG sprayed over the patches or to a control group. Two observers blinded to the randomization assessed the severity of adhesions to the patch by scoring the density of adhesions (grades 0-3) and the percentage of the patch area covered by adhesions (0-100%). The mean percentage of the patch covered by adhesions was 32.8 +/- 6.1 per cent for the FG group versus 57.9 +/- 6.7 per cent for the control group (P < 0.01). The mean density of adhesions for the FG group was 0.95 (+/-0.17) versus 2.0 (+/-0.21) for the control group (P = 0.001). Topical FG reduces the severity and density of intra-abdominal adhesions in a rat model.
