[The most important abdominal surgical emergencies in the newborn].

The neonatal period should be considered, in itself, as one of high risk, due to its natural anatomical and physiological lability. It is in this age, when characteristic pathological processes do occur, mainly digestive abnormalities, neonatal nectrotizing enterocolitis, Hirschsprung's disease and others. The authors report a four years statistical analysis in the Pediatric Surgery Service of the General Hospital "La Raza" Medical Center. There were 126 patients operated in the neonatal period. The treatment given in each case and the results obtained were compared with reports from the international literature.
