The objective: to evaluate indications and to develop optimal techniques of stenting for obstructing cancer of upper digestive tract, prevention and treatment of complications after stenting.

Material and methods. From 2000 to 2012 endoscopic stenting of esophagus, stomach, duodenum was performed in 488 cancer patients. We placed 546 metallic self-expandable stents, of which 77% was CHOO and HANARO (M.I.Tech), 19% – GIANTURCO Z (Wilson-Cook), other stents – 4%. There were 315 men (64.5%), 173 (35.5%) women, the mean age was 73 y.o. The obstructing esophageal cancer occurred in 250 patients, cardial – in 119, fundal-sited – in 29, gastric outlet – in 19, for recurrence in anastomosis – in 22. In 31 (6%) patients indication for stenting were as follows: а) early anastomosis dehiscence in 12 (2%) patients; б) esophageal-respiratory or esophageal-mediastinal fistulas – in 15 (3%) patients; в/ esophageal perforation – in 4 (1%).

Results. All patients had recovery of nutrition. In the group of obstructing esophageal cancer 13-day mortality rate was 14%, the median survival rate – 5 months, migration or damage of stent – in 31 (11.5%), recurrence of dysphagia – in 22 (8.3%). In the group of obstructing cardial and fundal cancer 13-day mortality rate was 12%, the median survival rate – 7 months, migration or damage of stent – in 18 (12.2%), recurrence of dysphagia – in 15 (10%). Hermetic enclosure and healing of anastomosis dehiscence was achieved in 9 (75%) of 12 patients.

Conclusion. Placement of self-expanding stents in patients with malignant obstruction of esophagus and stomach is optimal option of palliative care improving quality of life and associated with low rate of complications.

KEY WORDS: metallic self-expanding stents, incurable patient, obstructing esophageal cancer, obstructing stomach cancer, anastomosis dehiscence.
