Anorectal electromyography using intraluminal electrodes was carried out on both an aganglionic and a ganglionic segment of the patients with Hirschsprung's disease, The results of present studies were as follows; 1) The spike bursts of ganglionic segment were observed frequently. However, those of aganglionic segment were very rarely observed. 2) The conduction of spike bursts between the anal canal and ganglionic segment was frequently observed. On the contrary, the conduction of spike bursts between anal canal and aganglionic segment was absent in the patients with Hirschsprung's disease. 3) The patterns of the electromyography, which was analysed by signal processor,made spike bursts more clear than those obtained the conventional electromyography. These results suggest that rectal electromyography using intraluminal electrodes is useful for the diagnosis of Hirschsprung's disease.
