Duodenal stents are frequently used for palliating malignant gastric outlet obstruction. Successful stent placement relieves obstructive symptoms, is cost effective, and has a relatively low complication rate. However, enteral stents have the potential of migrating distally and rarely, even lead to bowel perforation. We present a rare case of a duodenal stent placed as a palliative measure for gastric outlet obstruction due to unresectable pancreatic cancer that migrated distally after a gastrojejunostomy resulting in small bowel perforation.
十二指肠支架常用于缓解恶性胃出口梗阻。成功放置支架可缓解梗阻症状，具有成本效益，且并发症发生率相对较低。然而，肠内支架有向远端迁移的可能性，甚至很少会导致肠穿孔。我们报告一例罕见病例，因不可切除的胰腺癌导致胃出口梗阻而放置十二指肠支架作为姑息治疗措施，该支架在胃空肠吻合术后向远端迁移，导致小肠穿孔。
