[Clinico-morphologic parallels in acute forms of Hirschsprung disease in newborns and infants].

39 newborns with an acute form of Hirschsprung's disease were under observation: rectal form 18%, recto-sigmoid 28.2%, subtotal 25.6%, total 28.2%. Clinical manifestations appeared soon after the birth and were characterized by the impediment of the meconium discharge, vomiting or eructations, abdominal swelling. The evaluation of the validity of histochemical and histological diagnostic methods in infants and morphologic description of the tissue acetylcholinesterase activity are presented. Hypoganglionic form of the disease was found in 4 cases. Clinical and morphologic picture of the hypogangliosis in newborns is described.
