Neonatal gastrointestinal perforation

Abstract

During the 7-year period from 1980 to 1986, 56 neonates with gastrointestinal (GI) perforation were treated in the Hospital for Sick Children, London. The overall mortality rate was 30%. The highest mortality rate (60%) was associated with gastric perforation, which in this series occurred only in premature neonates. Colorectal perforation carried the lowest risk of mortality (17%). The mortality rate from small bowel perforation was 35%. Prematurity and low birth weight were significant factors increasing the mortality rate from neonatal intestinal perforation. The predominant cause of perforation in the small and large intestine was necrotizing enterocolitis and the most common site of perforation was the terminal ileum. Mechanical ventilation was thought to be the cause of the perforation in four of the five neonates with gastric perforation. Primary anastomosis is a definite option in neonates who are stable intraoperatively. The mortality rate and in-patient stay for neonates who had primary anastomosis were less than for those who had stomas.
