[Solving of complications arising during and after application self-expandible metallic stents in palliation of malignant dysphagia].

ABSTRACT

INTRODUCTION: During palliative treatment of malignant disphagia in inoperabile patients various and serious complications may occur and compromite the method of treatment if there were not solved. AIM: Goal is to present the most frequent complications due to esophageal stenting and the way of their solving. MATERIALS AND METHOD: From 1996. to 2009. in 237 patients (164 esophageal carcinoma, 33 carcinoma of the esophagogastric junction, 14 bronchial carcinoma, 7 esophagojejunal anastomosis, 9 esophageal fistulas) 245 stents have been placed (54 uncovered and 191 covered). Mean survival period was 14.7 months (ranged from 1 do 33 months). Esophageal perforation (1), stent migration (9), malignant tissue ingrowth (31) and overgrowth (24) have been revealed by barium contrast study during follow up. Perforation was solved by placing covered stent, migration by removing migrated stent endoscopically or surgically, ingrowth and overgrowth by balon dilating or restenting under the fluoroscopically guidance and control. CONCLUSION: One can expect and recognize complications regarding esophageal stenting because it is the only way for their sucsessfull treatment.
