Patients and methods
The study involved 121 consecutive EA patients treated at Kobe Children's Hospital between January 1980 and December 2005. This study was done with the approval of the institutional review board (registered no. R20-3). The data collected included the anatomic type of EA, operative interventions, gestational week, weight at birth, presence of major cardiac anomalies, presence of associated anomalies other than cardiac anomalies, presence of chromosomal abnormalities, and patient outcomes. Major
Results
A total of 121 infants with EA were admitted to our institute over the 26-year period. Anatomic variations of total cases were as follows: EA + distal tracheoesophageal atresia (TEF), 101 (84%); EA + proximal TEF, 1 (1%); EA + distal and proximal TEF, 1 (1%); pure EA, 15 (12%); and H-type EA, 3 (3%). Among the 121 infants, there were 67 males and 54 were females. Average of birth weight of all cases was 2,330 ± 660 g, and the average gestational week was 37 ± 3 weeks. Spitz classification were
Discussion
In 1962, Waterston et al1 proposed a prognostic classification of EA, which was based on birth weight, pneumonia, and associated congenital anomalies. One of the important points of its classification was respiratory state of EA neonate. In response to advances in neonatal care, Poenaru et al12 suggested that only severe pulmonary dysfunction requiring mechanical ventilation remained a prognostic risk factor in their series, and proposed a new classification based on preoperative ventilator
