Endoscopic variceal ligation (EVL) is a promising new method for controlling actively bleeding oesophageal varices as well as for their eradication. Compared to conventional endoscopic injection sclerotherapy, EVL has a lower rebleeding rate, fewer complications and can achieve faster variceal obliteration. Disadvantages of EVL include overtube trauma and possibly longer procedure time. However, recent development of newer devices such as the multiple banding ligator may overcome these shortcomings and improve results.
内镜下静脉曲张套扎术（EVL）是一种很有前景的控制食管静脉曲张活动性出血以及消除静脉曲张的新方法。与传统内镜注射硬化疗法相比，EVL的再出血率更低、并发症更少，并且能更快地实现静脉曲张闭塞。EVL的缺点包括外套管创伤以及手术时间可能更长。然而，诸如多环套扎器等新型设备的最新发展可能会克服这些缺点并改善治疗效果。
