Colon laudering is used in many colon surgeries. The LIATO, that promotes cleanness of colon, demonstrates an increase of the surgical time and increase risk of infection. This study compares colonic anastomosis with and without preparation, through histomorfometric analysis. 30 rabbits were submitted to the surgery treatment and had been evaluated and divided in groups: group 1 (control) and group 2 (LIATO). Carried through statistical study with the program Prism® 4 for p< 5%. The analisis found acute inflammatory infiltrated with discrete bigger average in the anastomoses of group 2. Chronic inflammatory infiltrated with average of 1,9 in the anastomoses of group 2 and of 2,1 in the ones without preparation. Necrosis in 15,7% in the LIATO against 13,5% in the group without preparation. Calcium deposit in 43% of the anastomoses with preparation and in 30%, of the ones without preparation. Bigger colágen concentration were met in the anastomoses made with the intestinal laudering. Incidence of interlaced colagen fibres was observed in 86% of the anastomoses of the searched one and in 70% in the control group. We conclude that the LIATO presents better incidence of interlaced colagen fibres and fibre concentration resulting in better anastomosis.
