A two-point rectal mucosal biopsy (utilizing a histochemical study), namely biopsies at sites 5 to 10 mm and 30 to 50 mm oral to the dentate line, was developed to differentiate patients who can be treated adequately by rectal myectomy without colostomy and those who require other definitive surgery for Hirschsprung's disease. The examinations were performed in 28 patients suspected having a short aganglionic rectum. Ganglion cells were demonstrated by upper biopsy in four of 13 neonates, six of nine infants, and three of six children. These cases were successfully treated by rectal myectomy. The two-point rectal mucosal biopsy is useful not only for making definitive diagnosis but also for the selection of the surgical treatment for patients with Hirschsprung's disease.
