Influence of proximal end diverting colostomy on the healing of left-sided colonic anastomosis: an experimental study in rats.
The purpose of this study was to evaluate the healing of an experimental left-sided colonic anastomosis in rats protected by an end diverting proimal colostomy. The anastomoses were studied by radiological and biochemical examination and breaking strength was estimated. The results were compared with a non-operated group and with a group of rats having a non-defunctional anastomosis constructed in the same manner. In animals with an end diverting colostomy, anastomotic protein levels and enzymic activity were lower than in those with a colostomy, and the development of anastomotic strength was delayed compared with those not defunctioned.
