Gastrointestinal perforations in the neonatal period

Abstract

Forty-eight neonates were treated for gastrointestinal perforation during a 9-year period. In 30, perforation occurred within the first week of life. Thirty-six were preterm infants and many had a history of obstetric and postnatal complications. Perforation resulted from necrotizing enterocolitis in 26 patients, whereas in 14 neonates spontaneous perforation occurred in an apparently normal bowel, with no evident cause (idiopathic perforation). In 6 patients perforation was associated with meconium ileus. Primary closure was carried out for perforations of the duodenum and stomach. Intestinal perforations were usually treated by resection and enterostomies. The overall mortality rate in this series was 46%. The highest mortality rate was associated with necrotizing enterocolitis (62%). The mortality rate was only 14% in patients with idiopathic perforation. Despite improvement in the prognosis of neonatal gastrointestinal perforations in recent years, it is still discouraging, reflecting the difficulty in preventing and treating necrotizing enterocolitis.
