Abstract. The results of endoscopic treatment of 199 patients with stenosing malignant tumors of the esophagus with the use of endoscopic self-expanding stents, treated in the Nizhny Novgorod Regional Clinical Oncology Center in the period from 2014 to 2018. The average age was 66.6 years, the number of men ― 146, women ― 53. Stenting was used in patients with various degrees of dysphagia: 1 degree ― 0 (0%), 2 degree ― 15 (7.6%), 3 degree ― 122 (61.4%), 4 degree ― 52 (26.2%). In addition, patients with a relapse of malignant tumors in the zone of anastomoses after previous operative treatment were included. Localization of the stenosing tumor: the upper third of the esophagus ―16 (8.0%), the middle third of the esophagus ― 52 (26.1%), the lower third of the esophagus ― 100 (50.2%), the EGJ ― 19 (9.5%), relapse after surgical treatment ― 11 (5.5%). Relapse of dysphagia was observed in 22 patients (11.0%). Complications took place in 41 patients (20.7%), 67 patients (33.7%) had pain syndrome, as well as signs of reflux-esophagitis. Early chemoradiotherapy was in most cases associated with complications. Pain syndrome was the most common undesirable phenomenon.
