ABSTRACT

• A survey on intestinal atresia was made among 34 members of Korean Association of Pediatric Surgeons about the patients who were treated from the January 1, 1994 to December 31, 1996. The response rate was 82.4%. Two hundred and fifteen patients were analyzed. The lesion occurred in 73 cases at duodenum, in 72 cases at jejunum, in 71 cases at ileum and 2 cases at cecum and sigmoid colon each. There were 2 cases of combined anomalies (DA + JA + IA and DA + JA). Male to female ratio was 1:1 in duodenal atresia. and 1.8:1 in jejunoileal atresia. Seventy-four cases (34.3%) were premature babies (DA 35.2%, JA:48.6%, IA:19.2%), and 62 cases (28.7%) had low birth weight (DA:39.4%, JA 33.0%, IA:13.7%). Antenatal diagnosis was made in 92 cases (43.6%). However 22 cases (23.9%) of them were transferred to pediatric surgeon after delivery. Maternal polyhydramnios was observed in 63 cases (28.9%). Seventy-five cases (34.4%) were taken only simple abdominal film for diagnostic studies. The associated malformations were observed in 54 cases (24.8%) of intestinal aresia and more frequently observed in duodenal atresia (35 cases, 47.9%). Meconium peritonitis due to intrauterine bowel perforation was more frequently associated with ileal atresia compared to duodenum and jejunum. The overall mortality rate was 30%.
