为了解门脉高压食管静脉曲张胃食管返流情况，采用２４小时ｐＨ监测４３例肝硬化食管静脉曲张患者食管ｐＨ动态变化，并对比出血组（２５例）与未出血组（１８例），发现：①门脉高压食管静脉曲张返流阳性率达６２８％（２７／４３）。②出血组（１８／２５）与未出血组（９／１８）比较无显著差别（ｐ＜０１）。③总返流次数出血组（４０３５３±１６２５０），明显多于无出血组（２０４１０±１９７５０）（ｐ＜００５）。④长于５分钟返流次数：出血组（９０±８８１），无出血组（４８±２６５）两组比较（ｐ＜００１）有显著性差异。⑤ｐＨ＜４００的总时间（分钟）：出血组（３７３７５±１８５７０），无出血组（１１３２５±８５８０），两组比较（ｐ＜００５）。⑥不同静脉曲张程度的比较：重度曲张总返流次数明显多于中度曲张（ｐ＜００５）。结论：①肝硬化门脉高压食管静脉曲张存在胃食管酸返流，且与静脉曲张程度呈正相关；②胃食管酸返流在食管静脉破裂出血中起重要作用 In order to understand the situation of gastroesophageal reflux in patients with esophageal varices, 24-hour pH was used to monitor esophageal pH in 43 cases of esophageal varices with cirrhosis and 25 cases with and without hemorrhage (18 cases) : ① The positive rate of portal hypertension in esophageal varices was 628% (27/43). ② There was no significant difference between bleeding group (18/25) and non-bleeding group (9/18) (p <01). ③ The total number of reflux was significantly higher in the bleeding group (40353 ± 16250) than in the non-bleeding group (20410 ± 19750) (p <005). ④ The number of reflux in longer than 5 minutes was significantly different between the two groups (p <001) in the bleeding group (90 ± 881) and no bleeding group (48 ± 265). ⑤pH <400 total time (minutes): bleeding group (37375 ± 18570), no bleeding group (113  25 ± 8580), the two groups (p <0  05). ⑥ Comparison of varicose veins: The total number of severe varices was significantly higher than that of moderate varices (p <005). Conclusions: ① There is gastroesophageal reflux in cirrhotic patients with portal hypertension and positive correlation with varicose veins; ② The gastroesophageal reflux disease plays an important role in the rupture of esophageal varices
