目的 观察与评价内镜下带膜金属支架置入术联合放射治疗 (放疗 )治疗中晚期食管癌的临床可行性及疗效。方法 对 18和 16例中晚期食管癌病人分别行内镜下带膜金属支架置入术和支架联合放疗。观察CES型不锈钢金属支架对放疗射线分布的影响、比较单纯支架治疗和联合放射治疗病人的生存率、临床症状缓解率及并发症发生率。结果 ①CES型不锈钢金属支架对放疗射线分布无影响 ;②单纯支架组与联合治疗组病人在吞咽困难症状缓解及并发症发生率方面无差别 ;③联合治疗组病人的 6、9、12个月的生存率明显高于单纯支架组。结论 内镜下金属支架置入联合放疗是治疗中晚期食管癌的可行方法 ,其临床疗效明显优于单纯支架置入术
Objective To observe and evaluate the clinical feasibility and efficacy of endoscopic advanced metallurgical stenting combined with radiotherapy (radiotherapy) in the treatment of advanced esophageal cancer. Methods 18 and 16 patients with advanced esophageal cancer underwent endoscopic submucosal metal stent placement and stent combined radiotherapy. Observe the effect of CES-type stainless steel metal stent on radiation distribution of radiotherapy, compare the survival rate, clinical symptom remission rate and complication rate of the patients with simple stent treatment and combined radiation therapy. Results 1 The CES type stainless steel stent had no effect on the radiographic distribution of radiation; 2 The patients in the simple stent group and the combined treatment group had no difference in the remission of dysphagia and the incidence of complications; 3 The patients in the combined treatment group had 6, 9 and 12 months The survival rate was significantly higher than that of the simple stent group. Conclusion Endoscopic metal stent placement combined with radiotherapy is a feasible method for the treatment of advanced esophageal cancer. Its clinical efficacy is significantly better than that of simple stenting.
