Management of esophageal atresia and early predictive factors of mortality and morbidity in a developing country.

The aim of this study is to investigate management and outcome in esophageal atresia (EA) and to identify early predictive factors of morbidity and mortality in a developing country. Charts of neonates with repaired EA from 2007 to 2016 were reviewed. Patients' characteristics, operative details, and postoperative outcomes were collected. Statistical analyses were performed to identify predictors of complicated evolution. Forty-two cases were collected. There were 14 girls and 28 boys. Only one patient had antenatal diagnosis (2.3%). The mean gestational age was 38 weeks. Nine patients (21.4%) weighed less than 2.5 kg. Seventeen (40.4%) patients had associated malformations most commonly cardiac (9/17). Thirteen patients had delayed diagnosis (30.9%). Thirty-nine (92.8%) patients underwent primary esophageal anastomosis. Overall survival was 76.2%. Nineteen patients (57% of survivals) had complicated evolution before the age of one year and 15 patients (46.8% of survivals) developed complications after the age of one year. Perinatal variables associated with mortality were prematurity (p=0.004, OR=5.4, IC95%=[1.13-25.80]), low birth weight (p=0.023, OR=7, IC95%=[1.38-35.47]), cardiac malformations (p=0.006, OR=10.5, IC95%=[2.03-54.27]) and delayed diagnosis (p=0.005, OR=10.11, IC95%=[2.005-50.980]). Variables associated with short-term and middle-term complications were duration of intubation (p=0.019, OR=0.118, IC95%=[0.019-0.713]) and the presence of short-term complications (p=0.016, OR=7.33, IC95%=[1.467-36.664]) respectively. These factors may be used to identify patients who will benefit from more intensive follow-up program.
