Neonatal intestinal perforation is mainly caused by necrotizing enterocolitis, intestinal atresia, meconium ileus or unknown etiology. Occasionally, Hirschsprung's disease presents with neonatal intestinal perforation, of which, it is known that total colonic aganglionosis is common. Therefore, Hirschsprung's disease should be considered as a cause of neonatal intestinal perforation.
The authors have experienced 3 cases of neonatal Hirschsprung's disease associated with colonic perforations. Cecal perforations were noted in 2 cases with aganglionosis from descending colon and sigmoid perforation in a case with aganglionosis in rectum. These cases will be discussed with literature review.
