Introduction: The aim of this study is to determine the incidence, morbidity and functional outcome of two techniques for Hirschsprung disease (single-stage Duhamel pull-through and tans-anal pull-through) in the neonatal age group. Method: All the neonates with Hirschsprung disease with short aganglionic segment (transition zone at recto-sigmoid junction) admitted during the last 6 years were ...

The lethal spotted (ls) mouse has been used as a model for the human disorder Hirschsprung's disease, because as in the latter condition, ls/ls homozygotes are born without ganglion cells in their terminal colons and, without surgical intervention, die early as a consequence of intestinal obstruction. Previous studies have led to the conclusion that hereditary aganglionosis in ls/ls mice occurs...

The enteric nervous system (ENS) is essential for normal motility and many other physiologic properties of the gastrointestinal tract.1 It is composed of intrinsic neurons, the cell bodies and most processes of which are located inside the bowel wall, and extrinsic nerve fibers that project into the gut from autonomic and sensory ganglia. Although extrinsic innervation modulates the activity of...

In 1886, Harald Hirschsprung first described two cases of infantile constipation with colonic dilation, but he did not suggest any etiology or therapeutic option. Over the past 30 years, many studies have revealed the clinical presentation, radiological and histological diagnoses, surgical procedures, epidemiology, and associated genetics related to colonic dilation. Hirschsprung’s disease (HD)...

The expression of nerve growth factor receptor in colon from 20 patients with Hirshsprung's disease and 10 controls was studied immunohistochemically. The myenteric and submucous plexuses in the ganglionic bowel and hypertrophic nerve trunks in the aganglionic bowel displayed strong expression of nerve growth factor receptor. The most important finding was the identical localisation of nerve gr...
