Recent studies showed that interstitial cells of Cajal ( ICC ) are thought to modulate gut motility as gastrointestinal pacemaker cells. The aim of this study was to evaluate the distribution of ICC in the bowel walls of patients who had variable motility disorders. The first group (G1) consisted of 2 children who had normal bowel habits. The second group (G2) consisted of 9 children who underwent definitive procedure for rectosigmoid aganglionosis. Five of them showed normal bowel movements after operation (G2-A) and another 4 had defecation difficulty with persistent megacolon after operation (G2-B). The patient in the third group (G3) had neuronal intestinal dysplasia and the fourth group (G4) consisted of 2 patients who suffered from idiopathic megacolon. Four neonates belong to the 5th group (G5) underwent ileostomy because of meconium obstruction without cystic fibrosis. The ICC were identified by immunohistochemistry using an anti C-Kit antibody. Immunopositive cells were stained with dark red colors. In the control specimens, ICC were distributed around the myenteric plexus and showed dendrite patterns in muscle layers. In aganglionic colons of G2-A & B, ICC were absent or scarcely distributed around myenteric plexus. In contrast, ICC were well distributed around myenteric plexus and between muscle layers in the ganglionic segment of G2-A; however, ICC were not present or decreased in the ganglionic colon of G2-B. The C-Kit positive cells were present in G3 and more darkly stained compared with G1. The colons of G4 showed absence or decrease of ICC in spite of presence of ganglion cells. C-Kit '+' cells were completely absent or markedly decreased in all 4 neonates of G5 at the time of ileostomy and the distribution of ICC was changed to normal pattern after restoration of colonic function. The results suggest that lack of ICC caused reduction of motility in the ganglionic colon and it may be responsible for the development of megacolon after definitive procedure of agnglionosis or idiopathic megacolon. Also delayed maturity of ICC may play a role in meconium obstruction of neonates.ope
