Burns of the esophagus by corrosive substances lead to the progress of post-burn scar strictures of this organ in 40–75 % patients. The results in cicatricial stenosis of the esophagus occurs in less than 10 % cases with timely taking of preventive measures. 433 patients with chemical burns of the esophagus were treated at the Department of Clinical Toxicology in the Penza’s Emergency Hospital Care of a name G.A. Zakharyina for the period 2005 to 2008. We have done the analysis of the cases history of these patients and have identifi ed factors that conducive to the formation of post-burn cicatricial strictures of the esophagus. Based on these data, we have created the neural network of prediction scars stricture of the esophagus after chemical burn. Based on neural network model, it was predicted a high risk of developing post-burn scar stricture of the esophagus in 5 patients (4.5 %) in the early and late period. Medical and preventive intraluminal dilatations manipulations were carried out to these patients for 30–40 days after the burn in the surgical hospital. The maximum period of survey was 12 months – esophageal stenosis in 5 patients were not found.
