Risk factors of stent migration in esophageal cancer patients who underwent fully-covered self-expanding metal stents for malignant dysphagia or tracheoesophageal fistula

More than 50% of esophageal cancer patients are diagnosed with advanced diseases and commonly experience dysphagia, some of whom even have tracheoesophageal fistula. Self-expandable metal stent (SEMS) is one of the recommended palliative methods, although complications such as chest pain and stent migration are not uncommon. The goal of this study was to examine the predictors of stent migration.
