Placement of a gastroduodenal self-expandable metallic stent (SEMS) is a safe and well-established procedure for the palliative care of malignant gastric outlet obstruction. There have been reported complications related to the SEMS procedure such as stent occlusion, migration of the stent, biliary obstruction, bleeding, and bowel perforation. Early detection and proper management of the complications are crucial to maintain the quality of life and prolong the life expectancy of the patients. In this article, we will discuss the diagnosis and treatment of SEMS-related complications.
