目的为了治疗及预防门脉高压后引起的食道、胃底静脉曲张破裂出血。方法胃镜前端安装静脉套扎器材，插入胃镜于食管腔，至贲门上２５～３ｃｍ处开始对曲张静脉套扎，套扎器前孔对准靶静脉，负压抽吸。靶静脉进入套扎器前孔内，视野为红色拉套扎牵引线。套扎器材上的胶圈脱下，套在被抽吸的静脉上。形成静脉球，依次至下而上多点套扎。结果本组４６例病人中，套扎后食管内无曲张静脉残留者２９例（６３％）；静脉曲线变细、变短，红蓝色征消失者１７例（３９％），总有效率１００％。结论食管静脉套扎能使曲张的静脉消失或减轻，达到治疗及预防食管静脉曲张破裂出血的目的 Objective To treat and prevent portal hypertension caused by esophageal and gastric variceal bleeding. Methods The front end of gastroscope was equipped with intravenous ligation equipment. The gastroscope was inserted into the esophageal lumen and the varicose veins were ligated at 2 ~ 5 ~ 3cm on the cardia. The anterior orifice of the ligation device was aligned with the target vein and suctioned with negative pressure. Target vein into the front hole of the ligation device, the vision of the red pull ligation pull line. Ringe on the ligation device off, set in the vein was aspirated. Formation of venous ball, followed by multi-point bottom-up ligation. Results Among the 46 patients, there were 29 cases (63%) in the esophagus after ligation without esophageal varicose veins. The venous curve became thinner and shorter, and 17 cases (39%) disappeared in the red and blue signs. The total effective rate was 100 %. Conclusion Ligation of esophageal varicose vein varicose veins can disappear or reduce, to achieve the purpose of treatment and prevention of esophageal variceal bleeding
