Gastric perforation. An unusual cause of ascites in a newborn baby.

We report a case of a low birth weight asymmetrical small for gestational age baby, who presented at the age of 20 hours with sudden abdominal distension. Since birth he has been breastfed and was kept with his mother. Absence of radiological findings of necrotizing enterocolitis or perforation at the time of presentation delayed the diagnosis for 48 hours. At laparotomy the baby was found to have perforation of the stomach with no evidence of other gastrointestinal disorder.
