title: Hirschsprung's disease and intestinal neuronal dysplasia--a frequent association with implications for the postoperative course.
abstract: Between 1991 and 1993, 106 newly diagnosed cases of Hirschsprung's disease (HD) were prospectively analyzed for the association of HD and intestinal neuronal dysplasia (IND) at ten pediatric surgical departments in central Europe. Hirschsprung-associated IND (HaIND) was found in 40% of cases. IND was disseminated in one-third and localized in two-thirds of the patients. Initial clinical symptoms were related to the length of the aganglionic segment, but not to the presence of HaIND. An enterostomy performed in 72 cases (67.9%) was located in a segment of pathologically innervated bowel in 50% of all cases, but in 72% of cases of HaIND. The proximal margin of the resected bowel showed pathological innervation in 44% of cases. Supplemental biopsies from the intestine (apart from diagnostic suction biopsies and biopsies at the enterostomy site) led to the first identification or definition of length of associated IND in 17.9% of cases. Postoperatively, the presence of long-segment aganglionosis or associated IND implied a delay in the restoration or normal defecation. Persistent constipation was found in 40% of patients with associated disseminated IND at follow-up at 6 months, compared to 20.6% in patients with isolated HD. These children needed secondary interventions more often than patients with associated localized IND or isolated HD. HaIND thus has clinical implications for the postoperative course if IND is disseminated.
