title: Gastrointestinal perforation in infants.
abstract: We found that the mortality rate was no greater in patients with necrotizing enterocolitis complicated by perforation compared with the rate in those with other causes of perforation in similar weight classes. Iatrogenic injuries had a 50 percent mortality rate in all gestational age and birth weight categories and, therefore, great caution and surveillance are of utmost importance when using invasive monitoring and therapeutic modalities to prevent this cause of perforation. Term infants had a preponderance of mechanical causes of perforation which mainly occurred in the foregut and proximal midgut, whereas premature infants have a preponderance of asphyxial or ischemic events underlying perforations which mainly occurred in the ileocolic region and were often associated with necrotizing enterocolitis. Although neonatal intestinal perforation is a catastrophic event, the very premature infant weighing less than 1,000 g at birth is at significantly greatest risk. The discouraging 20 percent survival rate in the less than 1,000 g premature infants presents a challenge to the surgeon, since the overall survival rate was 59 percent and the term infants had a 78 percent survival rate. A substantial share of the mortality in the infants weighing less than 1,000 g at birth relates to the occurrence of intracerebral hemorrhage and bronchopulmonary dysplasia. Vigorous medical and surgical approaches can be used to salvage premature infants in all weight classes with gastrointestinal perforation.
