先天性肝外肝管闭锁的婴儿,在生后70天前进行手术治疗最为理想,早期正确鉴别胆管闭锁和新生儿肝炎,对手术选择或避免不必要的手术都是至关重要的前提。为此目的,曾设计过若干非损伤性的鉴别方法,其中以~(131)碘—孟加拉玫瑰红粪便排泄试验比较准确,但颇不经济,所得结果易受粪便收集不全或污染尿液的影响。本文作者提出,收集24小时十二指肠液,观察有无胆色素,能准确判断胆管是否通畅。方法是在透视下将不透X线的French9号十二指肠管插至十二指肠第二、三段交界处,用玻璃管虹吸法收集十二指肠液,头12小时内每2小时收集一管,用肉跟观察颜色。如果各管均无胆色素,则继续收集12小
Congenital extrahepatic liver atresia in infants, 70 days after birth, the best surgical treatment, the early correct identification of biliary atresia and neonatal hepatitis, the choice of surgery or to avoid unnecessary surgery are crucial prerequisite. To this end, a number of non-invasive identification methods have been designed, in which the excretion of ~ (131) iodine-bengal rose feces is more accurate but less economical and the results are susceptible to incomplete fecal collection or contamination of the urine . The authors propose to collect 24-hour duodenal fluid to observe the presence or absence of bile pigment, can accurately determine whether the bile duct is unobstructed. Method is through the perspective of the radiograph of French9 duodenum inserted duodenal second and third junction, using glass tube siphon method to collect duodenal fluid, the first 12 hours every 2 hours to collect A tube, observe the color with the meat. If the tubes are free of porphin, then continue to collect 12 small
