Treatment of oesophageal varices by insertion of Murphy's button arrests haemorrhage but in 2/3 of the cases of secondary stenosis occurs between the 4th and 8th week. The use of Blakemore's probe contributes to this. It is a very severe stenosis in 15 p. 100 of the cases and may require insertion of a wire loop. Dilatation should be started as soon as the first symptoms appear.
通过插入墨菲氏钮治疗食管静脉曲张可止血，但在三分之二的病例中，继发性狭窄发生在第4至8周之间。使用布莱克莫尔探针会导致这种情况。在15%的病例中，这是一种非常严重的狭窄，可能需要插入金属丝环。一旦出现最初症状就应开始扩张。
