我国目前食管癌的发病率已高达21.0/10万(男)～12.3/10万(女)。不幸的是,在得以确诊时,50％以上(我国报道为10％～20％)的食管癌患者已丧失了手术机会,对于这些患者,治疗的目的只能是缓解症状。100多年来,医务人员进行了大量的临床实践,以寻求缓解恶性食管狭窄所致吞咽困难的最佳方法。支架置入即其中最重要的方法之一。1977年Arkinson采用内窥镜置入圆柱形塑料管道来治疗不能手术切除的食管肿瘤,但因其操作困难,并发症多,缓解吞咽困难不理想等原因,近10多年来已逐渐被自扩金属支架(SEMS)所取代。现将近年来SEMS的临床应用及进展情况作一简要综述。
The current incidence of esophageal cancer in China has as high as 21.0 / 100,000 (male) to 12.3 / 100,000 (female). Unfortunately, more than 50% of esophageal cancer patients (10% to 20% reported in China) have lost their chance of being operative when diagnosed. For these patients, the goal of treatment is only to relieve the symptoms. For over 100 years, healthcare professionals have conducted extensive clinical practice to find the best way to alleviate dysphagia due to malignant esophageal stenosis. Stent placement is one of the most important methods. 1977 Arkinson use of endoscopic cylindrical plastic pipe to treat unresectable esophageal cancer, but because of its operational difficulties, complications, ease of dysphagia and other reasons, the gradual expansion of the past 10 years has been gradually metal Stent (SEMS) replaced. Now in recent years the clinical application of SEMS and progress made a brief review.
