目的

研究血清CA199在阻塞性胆道疾病中的诊断价值。

方法

回顾分析278例阻塞性胆道疾病患者的血清CA199水平，分析不同疾病之间的差异，以及和胆红素水平之间的相关性。

结果

胆管癌中血清CA199水平明显高于胰腺癌和胆总管结石（P＜0.05），而胰腺癌和胆总管结石之间无明显差异；血清CA199水平在胰腺癌和胆总管结石病例中与血清胆红素水平存在明显相关(P＜0.01)，但是胆管癌病例中无相关。

结论

血清CA199水平有助于胆管癌的术前诊断。

Objective

To study the diagnosis interpretation of serum CA199 level in obstructive bile duct diseases.

Methods

278 patients of obstructive bile duct diseases had been analyzed the difference of serum CA199 level and clinical diagnosis, and the correlation between serum CA199 level and serum bilirubin level.

Results

The serum CA199 level was higher in cholangiocarcinoma than in pancreatic carcinoma and common bile duct stones（P＜0.05），but there were no difference between pancreatic carcinoma and common bile ductstones.SerumCA199 levelwas correlate with serumbilirubin levelin pancreatic carcinoma and common bile ductstones(P＜0.01).Conclusion SerumCA199 level has idealvalue in diagnosis of cholangiocarcinomapre-opration.
