title: Simplifying the Waterston's stratification of infants with tracheoesophageal fistula.
abstract: The survival of infants with tracheoesophageal fistula was stratified by David J. Waterston et al. in 1962. This classification has been used as a guide to direct the timing of operative intervention in these infants. This study examines the current applicability of this classification system. The hospital records of 64 infants with esophageal atresia and/or tracheoesophageal fistula were reviewed. The survival rate was analyzed as a function of the infants' risk stratification, birth weight, and additional anomalies. Twenty-three infants were in Waterston Group A, 20 infants in Group B, and 21 infants in Group C. The survival of all infants was 81 per cent. Six infants died after recognition of severe anomalies and withdrawal of care, four infants died of cardiopulmonary arrest, and two infants died of sepsis. The survival of infants in both Groups A and B was 100 per cent, in contrast to 43 per cent survival in Group C. Only infants who weighed <1800 g or had severe additional anomalies were at risk of dying. Therefore, the classification of infants with esophageal atresia and/or tracheoesophageal fistula may be simplified by combining Waterston's Groups A and B into a single risk stratum.
