[Appendical innervation in the long types of Hirschsprung's disease. Histological and histoenzymatic study].

On the basis of the fact that the autonomic innervation of the appendix reflects that of the caecum, that appendicectomy is easier and less dangerous than multiple biopsies of the wall of the colon and that frozen section and later study, with the aid of a rapid histoenzymatic technique, is more convenient than that of small fragments which are always difficult to orientate, the authors recommend this investigation in cases in which a syndrome of obstruction in the neonatal or postnatal period poses the problem of the diagnosis and emergency treatment for total absence of colonic ganglia.
