The experience of management of 426 children with chemical burns of the esophagus and the stomach has been analyzed. The necessity of earlier (up to 3 hours) lavage not only of the stomach, but also of the esophagus, is substantiated. It is considered advisable to carry out diagnostic fibrogastroesophagoscopy not later than 1 day after the trauma and to give up early prophylactic bouginage of the esophagus. The latfer rather stimulates sear formation than prevents it. The developed scheme of treatment was used in 256 patients with resultant decrease of postburn stenoses of the esophagus 3 times is the results of conventional methods of treatment.
