目的 评价动态持续十二指肠液检查对婴儿持续性黄疸的鉴别诊断价值。方法 应用婴儿十二指肠引流管动态持续收集十二指肠液 ,观察颜色、测定总胆红素值和γ 谷氨酰转肽酶 (γ GT)活性。结果 16 8例婴儿持续性黄疸中 133例十二指肠液呈黄色 ,总胆红素值≥ 8 5 μmol/L ,γ GT≥ 2 0IU/L ,经随访黄疸消退 ,诊断为婴儿肝炎综合征 ;35例十二指肠液无色或呈淡黄色 ,总胆红素值 <8 5 μmol/L ,γ GT <2 0IU/L ,经剖腹探查诊断为先天性肝外胆道闭锁。结论 动态持续十二指肠液检查能早期正确鉴别婴儿肝炎综合征与先天性肝外胆道闭锁
Objective To evaluate the differential diagnosis of persistent persistent jaundice in infants with dynamic continuous duodenal fluid examination. Methods The duodenal drainage tube was used to collect duodenal fluid continuously and observe the color. Total bilirubin and γ-GT activity were determined. Results Among 133 cases of persistent jaundice, 133 cases of duodenal juice were yellow, the total bilirubin value was ≥85 μmol / L, and γ GT≥20 IU / L. The diagnosis of infantile hepatitis syndrome was made after the follow-up of jaundice. 35 cases of duodenal juice colorless or pale yellow, total bilirubin <8 5 μmol / L, γ GT <2IU / L, diagnosed by laparotomy congenital extrahepatic biliary atresia. Conclusions Dynamic continuous duodenal fluid examination can correctly identify infantile hepatitis syndrome and congenital extrahepatic biliary atresia
