title: Recent evaluation of prognostic risk factors in esophageal atresia--a multicenter review of 223 cases.
abstract: In this study, 223 cases of esophageal atresia (Type IIIb: 85.7%; Type II: 5.8%; Type IIIc: 4.0%; Type IIIa: 2.2%; Type IV: 2.2%) from 6 pediatric surgery centers of Austria, were retrospectively examined for the following parameters and their influence on the prognosis: Birth weight (2494.7 +/- 702.0 g), gestation week (range 27-42 weeks; mean 37.3 +/- 3.1 weeks), sex (male: n = 128; female: n = 95), long-gap atresia (> or = 2 cm: n = 33), Tracheomalacia (n = 16), associated malformations (n = 122; cardiac 27.4%, renal 17.9%, skeletal 17.0%, anal: 10.3%, intestinal 9.9%, mediastinal 7.6%, chromosomal 2.2%), preoperative aspiration (n = 92), pneumonia (n = 96), anastomotic insufficiency (n = 45), empyema (n = 5), mediastinitis (n = 8), sepsis (n = 32), other medical complications (n = 122, in 80 infants), other surgical complications (n = 57). The mortality rate was 41.3% overall, from 1975 to 1991; however, it was 25% from 1987 to 1991 and 0% in 1991. A statistically significant correlation was found between prognosis and the following factors: Cardiac malformations (p = 0.0001), medical complications except aspiration and pneumonia (p = 0.0001), empyema (p = 0.0081), mediastinitis (p = 0.0214), and sepsis (p = 0.0295). These 5 significant factors were given different points and a prognostic score was calculated by the addition of these points. This score was predictive for survival in 90.6% of cases and for mortality in 94% of cases.(ABSTRACT TRUNCATED AT 250 WORDS)
