ABSTRACTIntroduction. The most used prognostic classifications in esophageal atresia are Waterston and Montreal. The purpose of this study was to search for prognostic factors for surgical complications such as dehiscence, refistulization, stenosis and mortality in our population.
Methods. Retrospective case-control study on a series of type III esophageal atresia operated in our center over 10 years with a follow-up of at least 2 years. Statistically tests were chi square, Student’s t test, and odds ratio.
Results. Prognostic factors for mortality were gestational age, acidosis or pneumonia at admission, Waterston C and Montreal II classifications, and days of mechanical ventilation. Complications associated with ventilation were risk factors for dehiscence. This latter is in turn a risk factor for refistulization, and along with gastroesophageal reflux both are risk factors for esophageal stenosis.
Conclusions. There are some specific factors in our population that enhance the risk of morbidity and mortality.
