PM Chung, MH Cho, JS Joo, SO Choi, SH Choi, YS Huh, and CHong The Korean Association of Pediatric Surgeons The first national survey on esophageal atresia and tracheoesophageal fistula was conducted to access the current status of its incidence. clinical manifestation, preop erative diagnosis and management, type of its anomaly, associated anomalies, and surgical results and course. The 43 members of the Korea Association of Pediatric Surgeons received questionnaires and registration forms to be filled out on each pa tient who were born during the three years from January I, 1992 through December 31, 1994. Questionnaires composed of six broad areas which include 1) preoperative diagnosis and management, 2) surgical technic, 3) long gap, 4) postoperative manage ment, and 5) complications and courses. A total of 148 cases was returned by 28 members working at 23 institutions and 27 members returped questionnaires. We ob tained the following results by analysis of the 148 cases of tracheoesophageal anoma lies. The incidence of tracheoesophageal anomaly was about 1/10,000- 11,000 in 1994, which is one third of that of anorectal malformations in Korea and the distribution of the patients was almost proportionate to the size of each province. Both sexes are about equally affected. Majority of the members make diagnosis of tracheoesopha geal anomaly by taking a simple infantogram with a radiopaque tube in upper pouch and a little under half(46%) prefers to perform echocardiography as a part of preop erative management to identify congenital heart disease and lateralize the aorta. - 149 - - :t.0 l-.21}!j- : ;IJ]l i'! ;IJ] 2 ~ 1995\1 - Esophageal atresia with distal TEF(87.50/0) was by far the most common and threre were pure esopahgeal atresia(5.6%), H-type TEF(2.l%), and so on. About half(49%) of the patients had one or more associated anomalies in addition to tracheoesopha geal anomalies. Congenital heart disease was associated in 46 cases(31 %), anorectral malfomations in 19 cases(13%), musculoskeletal anomalies in 15 cases(10%), gen itourinary anomalies in 10 cases(7%) and gastrointestinal anomalies in 7 cases(5%). Postoperatively, parenteral nutrition and assisted ventilation were given in 66% and 52% of patients respectively. Ninety three(74%) of 126 cases who underwent sug:ical procedure, experienced one or more complications such as respiratory complication (65%), leak(22%), stricture(21%) and so on. The survival rates related to the Waterston risk categories were 90.2% in grpup A, 71.4-75% in BI, B2, and C groups, and 28% in group C2 and the overall survival rate was 71.4%. Thirty six(28.6%) of 126 cases died of pneumonia/ sepsis(12 cases), respiratory failure(l2 cases), and con genital heart disease(4 cases). With short term follow-up, 69% of patients have been excellent whereas remainders of the cases have suffered from some sort of morbidi ty related to gastroesophageal reflux, recurrent respiratory infection, and esophageal stricure.
