Over a period of 10 years we have treated 10 patients with neuronal intestinal dysplasia (NID), including 3 in whom the entire intestinal tract was affected by NID, and one in whom small intestinal NID coexisted with total colonic aganglionosis. Three of these 4 patients have died and the one survivor requires parenteral feeding. The six patients with less extensive NID have all been treated successfully; three have required surgery (Duhamel procedure in 2 and colostomy in 1), but 3 responded to conservative measures. We have made detailed histologic studies, including acetylcholinesterase activity in all cases, silver impregnation studies in 4, and immunohistochemical investigation of the peptidergic innervation of the bowel in one case. Follow-up rectal biopsies have not shown any significant morphological changes with time, but functional improvement does occur and we suggest that the myenteric ganglia in NID may have the capacity for functional maturation.
