被覆支架成形术在食管癌姑息治疗中的应用

Palliative Treatment of Esophageal Carcinoma with Covered-Stent

为了对中晚期食管癌进行姑息治疗，作者采用涤纶被覆金属支架置入术对１６例食管癌患者进行了治疗，其中合并食管气管瘘者４例。支架的体部直径为１８ｍｍ或１２ｍｍ，支架两端直径是２２ｍｍ，支架体部和端部的连接处成钝角，以防止支架的移位。全部支架置入术均经口腔在Ｘ线监视下进行。所有病人的支架留置均获成功，未出现技术问题。在有食管气管屡的４例中，支架置入后症状均得到缓解，所有病人的摄食能力均有不同程度地改善。食管支架成形术对食管癌进行姑息治疗是提高患者生活质量的一个安全有效的方法。

In order to treat esophageal carcinoma palliatively,a dacron knit fabric-covered modified Gianturco metallic stent was placed in 16 patients.The body of the stent was 18mm or 12mm and the end portions were 22mm in diameter and connected at obtuse angle to prevent the stent from migration. There were four patients complicated with esophagotracheal fistula. All patients were treated by means of peroral intubation of the stent under fluoroscopic guidance. All stents were successfully placed without technical failure. Clinical symptoms of aspiration were relieved in the 4 patients with esophagotracheal fistula,Food intake ability of all patients was improved.Dacron knit fabric covered stent is safe and effective for palliative treatment of esophageal carcinoma.
