Abstract. The use of new, more gentle methods of eliminating colon strictures in clinical practice is becoming very popular due to the widespread growth of oncological, inflammatory bowel diseases and diverticular disease. The analysis of treatment 17 patients by means of endoscopic high-pressure balloon dilatation was carried out. In 12 (70,6%) patients with malignant neoplasms stenosing the lumen of the organ, the method was performed in combination with tumor stenting. In 10 (83,3%) cases, intestinal obstruction was resolved, and patients received surgical treatment according to national clinical guidelines. Stenting of tumor in one patient was complicated by stent migration in the cranial direction, which led to perforation of the organ. In another case, due to the extent of the tumor exceeding the length of the stent, the manipulation did not lead to the resolution of the obstruction. In both cases urgent surgical treatment was required in the mode of Hartmann’s operation. Balloon dilation was performed as an independent procedure in 5 (29,4%) patients with scarring stricture of anastomosis of non-tumor genesis. At the same time, three-time manipulation and elimination of a preventive stoma in a short period after endoscopic intervention allowed to avoid relapse and surgical removal of the anastomosis stricture. Thus, the initial experience of using the endoscopic high-pressure balloon dilatation of the colon strictures of various etiologies in a multidisciplinary hospital demonstrates its effectiveness.

Key words: endoscopic balloon dilation, stenting of tumor strictures, scaring stricture of anastomosis.
