本文报道镜检胆囊胆汁对确定胆石症和区别胆固醇结石与色素性结石的敏感性和特异性。对象与方法:两组病人,一组为胆石症77例(66例有症状,11例无症状);一组为因不同疾病剖腹探查的无胆石病人39例(11例有总胆管狭窄)。所有病例均在术中直接穿刺胆囊抽取胆汁,并接受胆囊切除术。取1～4ml 胆汁离心,上清液分别测定胆酸、胆固醇及磷脂含量,计算胆固醇饱和指致,以胆汁及其离心沉淀镜检胆固醇与胆红素盐晶体。胆石则肉眼观察并测定胆固醇及胆红素含量。胆固醇含量>40%干重且大于胆红素含量者定为胆固醇结石,余为色素性结石。
This article reports the microscopic examination of gallbladder gallbladder to determine the cholelithiasis and distinguish between cholesterol stones and pigmented stones sensitivity and specificity. PARTICIPANTS AND METHODS: Two groups of patients, one group consisted of 77 cholelithiasis (66 symptomatic and 11 asymptomatic); one group consisted of 39 patients without choledocholithiasis (laparotomy of 11 cases) undergoing laparotomy due to different diseases. In all cases, gallbladder was directly punctured during operation and cholecystectomy was performed. Take 1 ~ 4ml bile centrifugation, respectively, the determination of bile acids, cholesterol and phospholipid content of the supernatant to calculate the saturated cholesterol-induced, with bile and its centrifugal sedimentation microscopy of cholesterol and bilirubin salt crystals. Gallstones were visually observed and measured cholesterol and bilirubin content. Cholesterol content> 40% dry weight and greater than the bilirubin content as cholesterol stones, the rest is pigmented stones.
