    ABSTRACT: BACKGROUND: Various types of adhesion barriers are widely used to prevent intra-abdominal adhesion. However, few studies have compared the efficacy of adhesion barriers using the same animal model. The aim of this study was to compare the anti-adhesive effects of various barrier agents using a newly developed, severe adhesion model. METHODS: A severe adhesion model was established by excision of a 1-cm(2) intra-abdominal wall and application of cyanoacrylate in rat. Eighty male Sprague-Dawley rats (10 weeks old; 370 ± 50 g) were divided randomly into four groups (n = 20 each): the untreated control group, G-group using a hyaluronic acid and sodium carboxymethyl cellulose gel (Guardix-sol®), A-group using 4 % icodextrin (Adept®), and S-group using a hyaluronate-carboxymethyl cellulose membrane (Seprafilm®). The effect of each adhesion barrier was evaluated by means of the extent and severity of adhesion, difficulty of adhesiolysis scoring systems, and microscopic grade of fibrosis. RESULTS: The G-group showed no difference in adhesion score and fibrosis, the A-group demonstrated only a significantly lower fibrosis, and the S-group exhibited a significantly lower adhesion score and lower fibrosis compared with the control group. The S-group had a significantly lower adhesion score and reduced fibrosis compared with the G-group; however, no significant difference in adhesion score and fibrosis was noted with the A-group. CONCLUSIONS: The membranous barrier Seprafilm® may be effective in the prevention of adhesion in the condition of peritoneal injury combined with foreign material. Adept® showed a tendency of decreasing the severity of adhesion and was effective in the prevention of fibrosis.

    ABSTRACT: This experimental study evaluated the effectiveness and safety of using cyanoacrylate adhesive for sutureless colonic anastomosis and as a protective seal to prevent leakage. Sixty male Sprague-Dawley rats (300 +/- 10 g, 9 weeks old) were divided into three groups: in group I, the anastomosis was sutured in a single layer with 5-0 polypropylene; in group II, the anastomosis was fixed using N-butyl-2-cyanoacrylate (Histoacryl(R)); and in group III, the anastomosis was sutured and then sealed with N-butyl-2-cyanoacrylate. The rats were sacrificed on postoperative day 7. The anastomoses among the three groups were compared by measuring wound infection, anastomotic leakage, anastomotic stricture, adhesion formation, anastomotic bursting pressure, and histological appearance. No anastomotic leakage was observed in any group. Anastomotic stricture was significantly more extensive in groups II and III (p < 0.001). Bursting pressure was significantly lower in groups II and III (168 +/- 58, 45 +/- 21, and 60 +/- 38 mmHg for groups I to III, respectively, p < 0.001). The severity of inflammatory reactions was significantly greater and collagen deposition was significantly lower in groups II and III (p < 0.05). N-butyl-2-cyanoacrylate could be a useful method for sutureless colonic anastomosis based on the absence of anastomotic leakage, but it may impede healing of the colonic anastomosis. In addition, when used to seal sutured colonic anastomoses, cyanoacrylate may have a negative influence on anastomotic healing. The clinical use of N-butyl-2-cyanoacrylate in colonic anastomosis does not appear to be acceptable and safer anastomotic methods or alternative forms of cyanoacrylate should be developed.
