We, in 1967, introduced a new technique of abdominoperineal anorectoplesty (Nichidai Method) for high type of imperforate anus in which a blind rectal pouch is pulled through the puborectalis muscle under direct vision from the abdomen. In this paper, the essence of the technique and its postoperative functional results were presented. In clinical evaluations of anorectal function of 35 patients who became more than 5 years old (mean age; 15.0±4.8), 40% of them were determined as good, 46%, as fair and l4%, as poor. Further, in these patients, the anorecal function was objectively evaluated by using anorectal manometry, rediography, and pudenal nerve stimulation technique.
