The authors present their experience in the medical treatment of 1, 296 caustic esophageal injuries in children over the last 20 years in two study groups, one comprising the period up to 1989 and the other 1990 to 1996, comparing the different treatments used in each group. The treatment was based fundamentally on dilatations with anterograde mercury bougies, Savary bougies, or retrograde thread-guided bougies with gastrostomy. Pneumatic balloons or stenting procedures have also been employed in the last 3 years. Early fiberendoscopy was used systematically in the second group, which provides a more accurate evaluation of the esophageal lesions. Antibiotic coverage was done systematically during the first 10 days in all serious cases, while steroids were employed routinely only in the last 3 years. The results were similar in both groups, with a dilatation average of 32 in the first and 30 in the second group and an initial dilatation interval of 3 to 4 weeks in both. Using updated exploration and dilatation techniques, we drastically reduced the number of gastrostomies needed for retrograde thread-guided dilatations from 51 in the first group to 5 in the second, consequently improving the patients' life quality. There was no mortality and only five esophageal perforations, which did not require surgical treatment.
