The use of self-expanding metal stents for palliation of malignant dysphagia is increasing. Experience in 70 patients was reviewed with respect to the value of stenting and management of the complications encountered.
Oesophageal stents were inserted in 70 patients (42 men) of mean age 73 years with malignant oesophageal obstruction. Data regarding stent insertion and degree of dysphagia were gathered prospectively.
Seventy-six stents were placed in 70 patients. By the end of the study 57 patients had died and 13 were still alive. Three patients died within 3 days of stent insertion and dysphagia was relieved in 64 of the 67 patients remaining. Stent migration, tumour ingrowth and overgrowth, and food impaction were encountered during follow-up in eight patients.
Insertion of self-expanding metal stents for the palliation of malignant oesophageal obstruction is a successful therapy which can be carried out with relative ease. Palliation of dysphagia with an appropriate stent can be expected in up to 95 per cent of patients.
自膨式金属支架用于缓解恶性吞咽困难的情况日益增多。回顾了70例患者的治疗经验，探讨了支架置入的价值及并发症的处理。
对70例平均年龄73岁的恶性食管梗阻患者（42例男性）置入食管支架。前瞻性收集有关支架置入及吞咽困难程度的数据。
70例患者共置入76枚支架。研究结束时，57例患者死亡，13例仍存活。3例患者在支架置入后3天内死亡，其余67例患者中有64例吞咽困难得到缓解。随访期间，8例患者出现支架移位、肿瘤长入和过度生长以及食物嵌塞。
置入自膨式金属支架缓解恶性食管梗阻是一种成功的治疗方法，操作相对简便。使用合适的支架，预计高达95%的患者吞咽困难可得到缓解。
