Self-expanding removable stents are used for the treatment of esophageal strictures. Partially covered metal stents become embedded in the esophageal wall due to mucosal tissue reaction providing good anchorage. This can also lead to extreme difficulty in the removal of such stents. Several different individual techniques have been used in literature for removal of these esophageal stents. Ours is the first case using a combination of cryoablation and stent-in-stent technique for removal of an extremely difficult case of embedded esophageal stent.
自膨胀可移除支架用于治疗食管狭窄。部分覆膜金属支架由于黏膜组织反应会嵌入食管壁，从而提供良好的固定效果。这也可能导致此类支架移除极为困难。文献中已使用多种不同的个体技术来移除这些食管支架。我们的病例是首例采用冷冻消融和支架内置支架技术相结合的方法来移除嵌入性食管支架这一极其困难病例。
