肝硬化患者胃动力多因素相关性研究

目的 进一步了解肝硬化患者消化道运动功能紊乱的机理及各因素间的相互关系。 方法 对46例肝硬化患者行血浆血管活性肠肽(VIP)、胃泌素、胃动素(MTL)检测;胃电图、24 h胃内pH监测;同位素核素闪烁法检测胃排空,并与正常组对照。 结果 肝硬化组与正常组,血浆VIP分别为(14.5±4.8)pmol/L和(9.7±3.4)pmol/L,t=5.181,P<0.05;胃泌素分别为(58.6±29.8)pg/ml和(38.1±14.6)pg/ml,t=3.871,P<0.01;MTL分别为(360.0±54.2)pg/ml和(422.0±48.5)pg/ml,t=5.529,P<0.05。胃电图主频、主功率进餐前后均降低,正常慢波节律减少,胃动过缓增加。胃内2 4 h pH监测反流积分增加,胃排空延迟。多元线性回归分析,相互间有显著性相关。 结论 肝硬化患者存在食管胃运动功能紊乱,表现为胃电节律紊乱、胃排空延迟。血浆胃肠激素的异常。肝硬化患者胃内pH异常,存在胃十二指肠反流。

Multiple analysis on the gastric impetus associated factors in patients with liver cirrhosis

OBJECTIVE: To investigate mechanism and relation of some disorder motive forces of digest system in patients with liver cirrhosis. METHODS: Plasma vasoactive intestinal peptide (VIP), gastrin and motilin (MTL), electrogastrogram (EGG) and pH value of gastric juice in 24 hours; gastric elimination time by isotope. All above factors have been determined in patients with liver cirrhosis and analyzed with multiple linear regressions. While a group of normal cases has been observed as control. RESULTS: Compared to the control group, higher level of VIP and Gastrin and lower MTL down were observed in liver cirrhosis group (Plasma VIP, Gastrin and MTL are 14.8+/-4.8, 58.6+/-29.8 and 360+/-54.2 separately, t=5.181, 0.05, t=3.871, 0.01 and t=5.529, 0.05 separately). The EGG dominant frequency (DF) and dominant power (DP) decreased around diet; normal slow wave number (N%) decreased and gastric excretion time prolonged, lower bradygastrias (B%) and pH value of 24 hours gastric juice denoted the incline of return movement, there are remarked different with 0.05 or 0.01 separately. Throughout analyzing these factors with multiple linear regressions, there are remarkable relationship between liver cirrhosis and pH value of gastric juice; gastrointestinal hormone and EGG with 0.05 or 0.01. CONCLUSION: (1) There are remarkable gastro esophageal function abnormal which has been conveyed by disorder gastric electric physiology and gastric elimination time in patients with liver cirrhosis. It is suggested that unusual gastrointestinal hormone played an important role during these abnormal process. (2) There is remarkable changing of pH value of 24 hours gastric juice denoted the opposite movement of gastroduodenal juice in patients with liver cirrhosis.
