RESUMO
OBJECTIVE: The aim of the study was to find out whether patients who underwent esophageal atresia (EA) surgery suffered from nutritional problems, to compare the nutritional status of these patients with a control group, and to determine if there is a relationship between the type of atresia and the nutritional condition. MATERIAL AND METHODS: We selected 25 patients out of a total of 32 who underwent EA surgery in our hospital from 2000 to 2006. A retrospective was conducted study based on the information obtained from the medical histories. A case-control study was also carried out by selecting a control group from a randomized population. RESULTS: The analyses performed showed that the mean weight and height Z-score was always negative, but not below -2 SD. There was a significant decrease in the weight Z-score between 3 and 9 months and in the weight/size Z-score between 3 and 24 months. Significant differences in weight and size Z-score were found between cases and controls, but not in skin-fold thickness. Independently of the type of atresia and the presence or not of congenital heart defects, no significant differences were found. CONCLUSIONS: There are significant differences in the weight and height Z-score between cases and controls. We stress the need to be aware of the nutritional status in order to prevent changes that could lead to a further deterioration of the patient.
