| Research Abstract |
To assess abnormalities of sensory conduction and find new markers of anorectal function in anorectal disease in children, we have evaluated peripheral sensory perception and somatosensory evoked potentials produced by anorectal stimuration in patients with anorectal malformation in the long-term more than seven years. Anorectal sensation was also evaluated using electrical stimulation. There was no significant relationship between electrical anorectal sansation and clinical score. Reproducible evoked potential recordings after anorectal stimulation were difficult but possible in minority of subjects, and when recorded showed intersubject and intrasubject variation. Cerebral evoked potentials can not be reliably recorded after anorectal stimulation, and when recorded the several kinds of latencies are of too broad a range to evaluate anorectal function. It might be related to the difference between somatic and visceral pathways.
