[Results of treatment of esophageal atresia]

The aim of the study was to analyze morality, incidence of complications and influence of various prognostic factors on the outcome of patients with esophageal atresia. A retrospective analysis of the records of 109 consecutive cases of esophageal atresia and/or tracheoesophageal fistula operated in 1992-2001 was undertaken. Primary anastomosis was achieved in 68 (62.4%) patients, in 7 (6.4%) procedures aimed at esophageal substitution in future were performed and in 34 (31.2%) delayed anastomosis was primarily planned.

Major associated anomalies were found in 55 (50.4%), cardiac anomalies in 19 (17.4%), and more than one associates anomaly in 16 (14.7%) patients. The most frequent surgical complication was anastomotic leak in 11.9%, septic complications were the most frequent and occurred in 66 (60.5%) patients. Gastroesophageal reflux was diagnosed in 30.3% and treated surgically in 14.7% of infants. The overall mortality was 20.2% (22 patients). The most frequent cause of death was sepsis and/or pneumonia. Long gap esophageal atresia was not found to be a significant factor in mortality. Factors significantly increasing mortality were birth weight below 2000g (OR 3.94), cardiac anomalies (OR 3.95), and mechanical ventilation before the operation (OR 2.97).

Analysis of the outcome suggests that improved strategy in treating infants with multiple anomalies and more frequent attempts at primary anastomosis even in children in sub optimal general condition at diagnosis could decrease mortality.
