Abstract: | The problem of congenital and acquired defects of innervation of the distal colon has many unsolved questions for making clinical and histological diagnosis, classification and using methods of treatment. Clinical, radiological and morphological aspects of treatment of 153 patients aged from 2 days to 14 years with disturbances of the colorectal innervation were analyzed. Radiological examination was not sufficient for making the diagnosis. Histological signs of aganglionosis, hypoganglionosis, dysganglionosis, type-A and type-B neuronal intestinal dysplasia in full-thickness biopsy specimens were used to confirm the diagnosis of congenital defects of innervation of the distal colon. The scheme of patho- and morphogenesis and clinico-morphological classification of disturbances of the colorectal innervation were proposed. Hirschsprung's disease was classified as a variant of the disturbance of the colorectal innervation. |
