PURPOSE
The authors describe their experience with expanding metallic stents for the palliation of malignant dysphagia.
MATERIALS AND METHODS
During a 52-month period, 138 stents were inserted in 121 patients with malignant esophageal obstruction. The average age was 74 years; there were 78 men and 43 women. Data regarding the degree of initial dysphagia, presence of an esophago-respiratory fistula, effect of stent placement on swallowing ability, complications at the time of stent placement, and long-term survival were obtained.
RESULTS
An improvement in dysphagia symptoms was recorded in more than 95% of patients. The average survival after stent placement was 24 weeks. Complications necessitating further intervention occurred in 26 patients.
CONCLUSION
Insertion of self-expanding metallic endoprostheses for the palliation of malignant esophageal obstruction is an effective therapy that can be carried out with relative ease. Successful palliation of symptoms can be expected in more than 95% of cases.
目的
作者描述了他们使用可扩张金属支架缓解恶性吞咽困难的经验。
材料与方法
在52个月的时间里，为121例恶性食管梗阻患者插入了138个支架。平均年龄为74岁；男性78例，女性43例。获取了有关初始吞咽困难程度、食管气管瘘的存在情况、支架置入对吞咽能力的影响、支架置入时的并发症以及长期生存的数据。
结果
超过95%的患者吞咽困难症状得到改善。支架置入后的平均生存期为24周。26例患者出现需要进一步干预的并发症。
结论
插入自膨式金属内支架缓解恶性食管梗阻是一种有效的治疗方法，操作相对简便。超过95%的病例有望成功缓解症状。
