[Retrospective analysis of morbidity and mortality of intestinal atresias in newborns].

Objective: Intestinal atresia (IA) is the most common obstructive congenital malformation in the gastrointestinal tract. The aim is to describe the morbidity and mortality of AI in our series.
Methods: Retrospective study in infants with AI who underwent surgery in our hospital in the past 15 years. Descriptive analysis was performed by collecting clinical and epidemiological variables. Qualitative and quantitative statistical analysis were performed.
Results: A total of 32 patients, 40.6% (13) women and 59.4% (19) males, maternal age 31 ± 5 years. Prenatal care in 96.8% (30) and prenatal diagnosis in 68.8% (22). Gestational age 35 ± 3 (SG 25-41), birth weight 2,506 ± 516 g (920-3,470 g). 53% (17/32) were localized in duodenum (65% extrinsic, 35% type I); 37.5% (12/32) jejunoileal (16.6% type I, 25% type II, 16.6% type IIIa, 16.6% type IIIb and 25% type IV); 6.5% (2/32) were colonic and 3% (1/32) pyloric. In 65.6% (21/32) it was associated with other congenital malformation. 81.3% (26) were operated within the first 48 hours of life. 15.6% (5/32) required enterostomy. 21.8% (7/32) had complications requiring reoperation in 71% (5/7) with 1 case of short bowel syndrome. Median time to enteral nutrition onset was 10 days (IQR 7-15), higher in patients with ileal atresia. Hospital stay was 33 days (interquartile range 23-66 days) and overall mortality of 9.3%.
Conclusion: In our series the congenital malformations associated with intestinal atresia were determinant in the prognosis and mortality of these patients.
