早在30年代,经内镜注射硬化剂(Endos-copic injection sclerosis,EIS)治疗食管静脉曲张破裂出血,业已应用于临床。此法曾一度冷落,直到1973年,Johnston等报道了EIS治疗食管静脉曲张破裂出血15年的结果,才重新引起人们的重视。近年来,欧美一些国家趋于将EIS作为治疗食管静脉曲张破裂出血的首选方法,长期择期硬化治疗预防再出 As early as the 1930s, Endos-copic injection sclerosis (EIS) for the treatment of esophageal variceal bleeding has been used in clinical practice. This method was once neglected until 1973, Johnston and other reports of EIS treatment of esophageal variceal bleeding after 15 years of results, only to re-attract people’s attention.
