BACKGROUND
Self-expanding metal stents are widely used in the palliation of esophageal diseases (Todd, N Engl J Med 344(22):1681-1687, 2001). The majority are inserted for end-stage malignancy and are not designed to be removed.
METHODS
We report the first recorded successful endoscopic removal of an "irremovable" stent by laser fragmentation after its placement became redundant. A 72-year-old man who had persistent dysphagia after esophageal stent insertion for Boerhaave's syndrome had his stent removed by Nd-YAG laser fragmentation at staged endoscopies.
RESULTS
The stent was removed in its entirety and the patients' symptoms resolved.
CONCLUSIONS
We describe a successful technique for the removal of a nonretrievable stent using laser fracture and endoscopic retrieval. This method of stent removal has not been previously reported.
背景
自膨式金属支架广泛用于食管疾病的姑息治疗（Todd，N Engl J Med 344（22）：1681-1687，2001）。大多数支架用于终末期恶性肿瘤，且设计上不能取出。
方法
我们报告首例记录在案的经内镜激光切割成功取出“不可取出”支架的病例。一名 72 岁男性，因 Boerhaave 综合征行食管支架置入后持续出现吞咽困难，支架变得多余，在分期内镜检查时采用钕-钇铝石榴石（Nd-YAG）激光切割将其取出。
结果
支架完整取出，患者症状缓解。
结论
我们描述了一种使用激光断裂和内镜取出成功取出不可回收支架的技术。这种支架取出方法以前尚未报道过。
