The aim of this study was to determine the effectiveness of carboxymethyl chitosan(CMC) solution on preventing intraperitoneal adhesions. In this study, 44 rats were divided into four groups ; an untreated control group and three experimental groups that were treated with 3 §¢ of 1, 2 or 3% CMC solution, respectively. The anti-mesenteric serosa of the ileum was exteriorized and then abraded in a standard manner by scraping with a scalpel blade to create homogenous petechial hemorrhagic surface over a 0.5 ¡¿ 1 §¯ area. The adhesions were blindly assessed 2 weeks later by using a computerized tensiometer. The mean tensile strength(Newton) of formed adhesions was 2.48¡¾0.88 in control group, 1.86 ¡¾0.56 in the 1% CMC-treated group, 1.75 ¡¾0.71 in the 2% CMC-treated group and 1.55 ¡¾0.60 in the 3% CMC-treated group. The most favorable prevention against adhesion was achieved in the 3% CMC-treated group(p<0.01). We could conclude that CMC was effective on preventing the formation of postoperative small intestinal adhesions in the rat.
