Endoprosthetics for Malignant Esophageal Disease

Currently used stents for malignant esophageal strictures are include self-expanding metal (SEMS), plastic (SEPS) and biodegradable stents. For the palliative treatment of malignant dysphagia both SEMS and SEPS effectively provide rapid relief of dysphagia. SEMS are preferred over SEPS, as randomized controlled trials (RCT) have shown more technical difficulties and late migration with plastic stents. Despite specific characteristics of recently developed stents, recurrent dysphagia due to food impaction, stent migration and both tumoral and non-tumoral tissue overgrowth are common.
