ERCP联合胆汁肿瘤标志物测定对可疑胰胆管疾病的诊断价值研究

目的探讨胆汁肿瘤标志物测定在ERCP对可疑胰胆管疾病诊断中的辅助作用。方法对经B超、MRCP、生化、血清肿瘤标志物等常规检查未能明确诊断的可疑胰胆管疾病患者，进行ERCP检查或对症治疗，同时行胆汁肿瘤标志物测定，选取29例明确诊断的病例分为良性和恶性组，比较2组在生化、肿瘤标志物上的差别，同时评估和比较B超、EUS、MRCP、ERCP、ERCP＋胆汁肿瘤标志物对可疑胰胆管疾病的诊断价值。结果生化、血清癌胚抗原（CEA）、血清CA19-9、胆汁CA19—9，在2组间差异无统计学意义，而胆汁CEA在恶性组中平均值高于良性组，且差异有统计学意义（P〈0．001），ERCP联合胆汁CEA测定对可疑胰胆管疾病诊断准确率为69．0％（20／29），高于单纯的B超6．9％（2／29）、EUS60．0％（6／10）、MRCP37．9％（11／D）和ERCP41．4％（12／29）。结论ERCP联合胆汁的CEA测定能进一步提高可疑胰胆管疾病诊断的准确性，对良恶性疾病的鉴别诊断有着辅助作用。

Endoscopic retrograde cholangiopancreatography combined with tumor marker measurement in biliary juice in differential diagnosis of biliary-pancreatic diseases

Objective To investigate the diagnostic value of tumor marker measurement in biliary juice obtained during endoscopic retrograde cholangiopancreatography (ERCP) in differential diagnosis of suspected biliary-pancrentic diseases.Methods ERCP was performed in patients with suspected biliarypancreatic lesions that could not be diagnosed by routine methods including ultrasonography,MRCP,blood biochemistry and serum tumor marker test,and biliary juice was obtained to measure tumor markers including CEA and CA199.A total of 29 patients with definitive diagnosis were recruited and divided into benign and malignant groups.Serum biochemical findings and tumor markers were compared between 2 groups.The diagnostic value of uhrasonography,EUS,MRCP,ERCP and ERCP combined with biliary tumor markers were also compared.Results There was no significant difference in serum biochemical findings,serum CEA,serum CA19-9 or biliary CA19-9 between 2 groups,while the average biliary CEA in malignant group was significandy higher than that in benign group (P＜0.001).The accuracy of ERCP combined with biliary tumor markers in diagnosing suspected biliary-pancreatic diseases was 69.0%,which was higher than that of ultrasonography (6.9%),MRCP (37.9%) and ERCP (41.4%),respectively.Conclusion The diagnostic accuracy of suspected biliary-pancreatic diseases can be improved through ERCP combined with biliary CEA test,which is helpful in differential diagnosis between benign and malignant lesions.
