ABSTRACT
Placement of the self-expandable metallic stents for palliative treatment of malignant esophagogastric strictures has been thought to be easy, fast and effective method than conventional methods (bypass procedures, radiation therapy, laser treatment, esophageal intubation, etc.). The expandable metallic stent tubes were found to overcome some of the limitations of nonexpandable conventional tubes.
Their implantation is better tolerated and safer than that of nonexpandable tubes, because the risks of migration and perforation are lower.On our knowledge, there has been no report of pyloric obstruction after this metallic stent insertion.We hereby report a case of pyloric obstruction caused by a migrated self-expandable metallic stent for palliative treatment of malignant esophageal stricture.
