title: [Efficacy of extramucosal myotomy in an experimental model of intramural colonic obstruction. An experimental study in rats].
abstract: An experimental study over the efficacy of myotomy in the treatment of intramural colon obstruction is presented. Forty Wistar rats were used. Four groups were made with ten animals each: Group I: control; Group II: myenteric denervation of four cm segment of transverse colon; Group III: myenteric denervation of 4 cm segment of transverse colon and myotomy; Group IV: myotomy of segment of transverse colon. Myenteric denervation was produced by serosal application of 0.1% benzalkonium chloride during 30 minutes. Animals were evaluated by clinical parameters (survival, weight change, food intake, nutritional state), radiological (barium enema) and Histomorphometry. The myotomy is an effective technique for the treatment of the experimental model of colon obstruction used.
