目的：研究应用带膜自膨式金属支架治疗食管或贲门癌引起狭窄的支架下口部位的选择及其与疗效的关系。方法：先用Ｓａｖａｒｙ探条将２０例食管或贲门癌性狭窄患者的狭窄部位扩张至１２ｍｍ左右，经引导钢丝置入带膜自膨式金属支架，支架下口悬式架于食管或贲门病灶以下约２～３ｃｍ处（１８例）或同向卧置在胃肠粘膜上（２例）。结果：平均随访８个月，均进食通畅，生活质量明显改善。２例死于肿瘤转移性全身衰竭。未发生出血、穿孔等严重并发症。结论：应用带膜金属自膨式支架治疗食管或贲门癌患者的癌性狭窄，支架下口悬式或同向卧式架设效果理想，可避免架设过短或支架下口抵伸在胃肠粘膜内导致流出道受阻
Objective: To study the application of self-expanding metal stent with stent in the treatment of esophageal or cardiac cancer caused by stenosis of the lower mouth of the site of choice and its relationship with the efficacy. Methods: Savary probe was used to expand the stenosis of esophageal or gastric cardia stenosis to about 12 mm in 20 cases. The guide wire was placed in a self-expanding metal stent with a stent. The stent was hung under the esophagus or cardiac lesions About 2 ~ 3cm Department (18 cases) or in the same direction lying on the gastrointestinal mucosa (2 cases). Results: After an average follow-up of 8 months, all had smooth eating and quality of life improved significantly. 2 patients died of tumor metastatic systemic failure. No bleeding, perforation and other serious complications. Conclusion: The application of self-expanding membrane-covered stent in the treatment of cancerous stenosis in patients with esophageal or gastric cardia cancer, the stent hanging under the mouth hanging or the same horizontal horizontal erection ideal, to avoid short erection or scaffold arrived in the gastrointestinal mucosa Cause the outflow blocked
