The authors describe two patients with congenital atresia of the large intestine. Both patients had colostomy when neonates. A double colostomy was performed. The microcolon was dilated across the distal colostomy by physiological saline and semolina pudding to achieve dilatation of the distal portion. Occlusion of the colostomy, tapering and end-to-end colo-colo anastomosis was performed in both children at the age of four months. The passage was restored in both patients on the third day after occlusion of the colostomy. One patient had also other congenital defects, i.e. equinovarus of both feet and a defect of the atrial septum. One patient is four, the other three years old. They are doing well and have no digestive trouble.
