Abstract:
Objective To evaluate the diagnosis and treatment of intestinal neuronal dysplasia type B (IND) in childhood. MethodsForty-five patients underwent preoperative barium enema examination, 23 patients underwent electromanometry, and mucosal biopsy and immunohistochemical staining for S100 protein were performed in 17 cases. All 45 patients underwent resection of the invalid segment with coloproctostomy. Whole layer was sampled on several sites of the resected segment and examined by two independent pathologists. All patients were followed up from 3 months to 9 years (mean 4.6 years).ResultsTwenty eight patients were complicated with Hirschsprung′s disease, one patient with hypogangliosis, and isolated IND was diagnosed in the other 16 children. The narrowed distal segment with proximal dilatation was merely noted in 4 children with isolated IND. Internal sphincter relaxations were missing in 6 children with isolated IND. The indicative diagnosis might be merely gained in 7 patients by the mucosa biopsy. The correct diagnosis can be established by whole layer biopsy of the resected segment. Three children with enterocolitis after operation were cured by conservative treatment. One patient suffering from postoperative sluice syndrome underwent second resection. Postoperative continence was achived in all patients. ConclusionThe correct diagnosis of IND can be obtained by biopsy of whole layer, and resection of invalid bowel segment with coloproctostomy is the choice of therapy.
