The incidence of gastroesophageal reflux was evaluated with the use of a pH probe in 12 patients with cirrhosis and recent variceal hemorrhage and in 15 healthy control subjects. Short episodes of reflux occurred in 42% of the patients and in 47% of the controls. During an observation period of 1 hr, the cumulative duration of reflux was similar in patients (2.5 +/- 1.3 min) and controls (3.1 +/- 1.4 min). Mean lower esophageal sphincter pressures were normal in both groups but did not show a significant correlation with the duration of reflux. These data support previous observations that gastroesophageal reflux dose not appear to be a contributing factor in the development of variceal hemorrhage.
使用pH探头对12例肝硬化伴近期静脉曲张出血患者和15名健康对照者进行胃食管反流发生率评估。42%的患者和47%的对照者出现短暂反流发作。在1小时的观察期内,患者(2.5±1.3分钟)和对照者(3.1±1.4分钟)的反流累计持续时间相似。两组的平均食管下括约肌压力均正常,但与反流持续时间无显著相关性。这些数据支持了先前的观察结果,即胃食管反流似乎不是静脉曲张出血发生的一个促成因素。
