Resultados. La inclusión de titanio y Lactomer® en la línea anastomótica originó mayor número de adherencias y mayor poder adhesiogénico. El titanio indujo adherencias más difíciles de separar y mayor porcentaje de adherencias vasculares que el Lactomer®.
Conclusiones. La formación de adherencias postoperatorias perianastomóticas cólicas se ve influida por la cantidad de material incluido en la línea anastomótica. La naturaleza irreabsorbible del material de sutura empleado puede influir en las características de dichas adherencias.
Methods. An experimental study was carried out using 30 male Sprague-Dawley rats divided into three groups. The control group (n = 10) was subjected to colonic transection and monolayer discontinuous colonic anastomosis. The same procedure was performed in the other two groups, except that 8 mg of titanium were introduced along the anastomotic suture line in one and 8 mg of Lactomer® in the other. The intraabdominal adhesions were quantified and assessed five months later.
Results. The implantation of titanium and Lactomer® along the anastomotic suture line provoked a greater number of adhesions. Those produced by titanium were more difficult to separate and there was a greater number of vascular adhesions than those observed with Lactomer®.
Conclusions.. The formation of adhesions in the area of colonic anastomoses is influenced by the amount of material included in the suture line. The nonabsorbable nature of the suture material employed may have an impact on the features of these adhesions
