不同程度胆道感染的压力变化

INTRABILIARY PRESSURE AND ITS CLINICAL SIGNIFICANCE IN BILIARY TRACT INFECTION

本文对64例不同程度胆道感染的病例进行了胆道压力测定及肝组织扫描电镜观察。其中重症急性胆管炎24例,急性胆管炎20例,前组胆总管压力明显高于后组,两组病例肝脏病理变化亦有显著的差异。急性胆囊炎10例,细菌培养仅2例阳性,可见梗阻是其最主要的病因。同时测定10例胆囊壁无炎症改变的胆囊压,证明正常状态人胆道各部位之间亦是有压力梯度的。

The prospective study performod in 64 patients with biliary tract infectionstudied the pressure, hepatic changes and the correlation between them in diffe-rent degrees of infection. There were 24 cases of acute obstructive suppurativecholangitis (AOSC), 20 acute cholangitis (AC) and 10 acute cholecystitis. InAOSC, the hepatic demage was more severe than trat in AC. The positive rateof bacterial culture was 20 percent in AC,so we believed that the more importantfactor was obstruction rather than bacterial infection. The intraluminal pressureof the gallbladder in eight cases of gallstone and two cases of polyp was alsomeasured, that was lower than that of common bile duct. The result confirmsthat the pressure step of biliary tract also exists in the human race.
