Background:The ingestion of caustic substances constitutes a serious problem in the pediatric age that can cause injuries in the esophagus that may require oral feeding. Gastrostomy nutrition is a safe way to guarantee an adequate evolution of the nutritional status, as well patient's growth and development. Objective: The objective of the study was to evaluate the nutritional status of children with esophageal stenosis, secondary to caustic ingestion, after 6 months of gastrostomy placement as a feeding route. Methods: A descriptive, longitudinal ambispective study was carried out, with a sample of 20 patients. Nutritional status before and after gastrostomy placement; was obtained through anthropometric measurements and pediatric indexes. Statistical analysis: t-test. Results: The anthropometric indexes of W/A and BMI/A reflect a statistically significant improvement in nutritional status over 6 months of gastrostomy treatment, but not for H/A. Conclusion: The nutritional status evolves adequately from gastrostomy management in these patients.
