Background: Neonatal perforation of the esophagus appears to occur rarely and often can mimic esophageal atresia. This report presents 12 cases of pharyngoesophageal perforation with a review of the literature.
Patients: From 1980 to 1995, we treated 12 infants for pharyngo-esophageal perforation. Ten infants were pre-term, seven of them weighing less than 1,500 g. Five infants had severe respiratory distress. Four infants had repeated attempt on intubation of the airway and eight infants had a routine postpartum suctioning and gastric aspiration. On plain X-ray, a large right pneumothorax was observed in three cases and the nasogastric tube deviated widely from its expected course in three cases. Four infants underwent contrast esophagography and three infants esophagoscopy. In five cases esophageal atresia was the initial diagnosis. Five infants underwent a thoracotomy. A gastrostomy was performed in one case. The six remaining neonates were treated non-operatively: broad spectrum antibiotics, total parenteral nutrition, and silastic nasogastric tube. Follow-up was uneventful in five cases. One infant with an esophageal stricture underwent instrumental dilatation. Bronchopulmonary dysplasia occurred in two cases and necrotizing enterocolitis in one. Two infants died.
Conclusion: Iatrogenic perforation remains a difficult diagnosis. Clinical findings, plain chest x-ray and oesophagography are helpful. Surgery can be completely avoided in most instances. Infants with low birthweight and prematurity are most at risk.
