Purpose: Several risk classifications based on various preoperative factors have been proposed to prognosticate the immediate survival of children operated for esophageal atresia. A major drawback of these classifications is that they only focus on immediate survival while ignoring the long-term morbidity and mortality in these children. Our study aims to bridge this gap in knowledge by studying the impact of one such classification (Okamoto's classification) on mortality and morbidity during a period of 1 year after discharge from the hospital in operated cases of esophageal atresia.
Materials and Methods: After institutes ethical clearance, 106 children operated for esophageal atresia-tracheoesophageal fistula between 2012 and 2015 were studied prospectively for a period of 1 year after their discharge. The children were graded as per Okamoto classification. The primary objective was to determine the efficacy of this classification in predicting the survival rates in infancy and the secondary objective was to compare the complication rates in these children based on the classification.
Results: Sixty-nine children met the inclusion criteria. There were 40, 15, 10, and 4 children in Okamoto Classes I, II, III, and IV, respectively. Twenty-one patients (30%) died during the follow-up period with the maximum number of deaths occurring in Okamoto Class IV (75%) and the minimum in Okamoto Class I (17.5%) (P = 0.003). There was a significant correlation between the Okamoto classes with the incidence of poor weight gain (P = 0.001), lower respiratory tract infection (P = 0.007), and failure to thrive (P = 0.01) higher in Okamoto IV and III as compared to I and II.
Conclusion: Okamoto prognostic classification during the initial hospitalization is relevant even at 1 year follow-up with increased mortality and morbidity in Okamoto Class IV as compared to Class I.
