摘要： 摘要： 目的 探讨超声内镜（EUS）在逆行胆胰管造影术（ERCP）前对不明原因胆总管扩张的诊断价值。方法 60 例不明原因胆总管扩张患者， 经腹部超声（TUS）、 CT 和（或）磁共振胰胆管造影（MRCP）检查提示胆总管扩张、 可疑胆胰病变但原因不明， ERCP 术前行 EUS 检查诊断， 并以 ERCP、 手术病理及随访确诊的结果为最终诊断。结果经 ERCP 确诊为胆总管下端结石者 39 例， EUS 诊断 38 例， 另 1 例 EUS 诊为胆总管下端肿瘤。ERCP 及手术病理确诊为胆总管下端肿瘤 10 例、 胆管内乳头状瘤 2 例、 壶腹部肿瘤 2 例； EUS 诊断结果分别为 11 例、 0 例及 3 例， 其中 1 例确诊为胆总管下端结石者 EUS 提示为胆总管下端肿瘤， 2 例确诊为胆管内乳头状瘤患者 EUS 将其中 1 例诊断为炎性狭窄， 另 1 例诊断为壶腹部肿瘤。术后随访确诊为十二指肠乳头炎性狭窄 7 例， EUS 诊断结果为 8 例， 其中 1 例术后随访并经 ERCP 病理确诊为胆管内乳头状瘤。诊断正确率 95% （57/60）。结论 EUS 对不明原因胆总管扩张的定位及定性诊断均有很高的诊断价值， 特别是能提高胆总管下端结石确诊率， 高于 MRCP 检查， 并能指导选择性地进行 ERCP， 提高治疗效果， 减少风险。

Abstract: ponding Abstract： Objective To evaluate the diagnostic value of endoscopic ultrasonography (EUS) for unexplained bile duct expansion in patients before retrograde cholangiopancreatography (ERCP). Methods Sixty patients with unknown causes of bile duct dilatation were included in this study. Patients were examined by abdominal ultrasound (TUS), CT and (or) magnetic resonance imaging (MRCP) suggesting the dilatation of common bile duct, suspecting biliary pancreatic disease with unknown cause. EUS diagnosis was performed before ERCP surgery. The final diagnosis was confirmed by ERCP, pathology and follow-up diagnosis. Results Thirty-nine patients were diagnosed as distal bile duct stone by ERCP, 38 were diagnosed by EUS, and one case was diagnosed as common bile duct bottom tumors by EUS. There were 10 cases were diagnosed as common bile duct bottom tumors by ERCP and surgical pathology, 2 cases were diagnosed as biliary papillomatosis, 2 cases were diagnosed as periampullary carcinoma. There were 11, 0 and 3 cases were diagnosed by EUS. One case was diagnosed as distal bile duct stone, which was diagnosed as common bile duct bottom tumor by EUS. Two cases were diagnosed as papillary tumor of the bile duct, one of which was diagnosed as inflammatory stenosis, another one was diagnosed as periampullary carcinoma by EUS. Results of postoperative follow- up confirmed that 7 cases were duodenal papilla inflammatory stenosis. Eight cases were diagnosed by EUS, one of them was followed up and pathologically diagnosed as biliary papillomatosis by ERCP. The diagnostic accuray was 95% (57/60). Conclusion EUS has higher value in the diagnosis of unexplained bile duct expansion, which especially can improve the diagnostic rate of distal bile duct stone compared with that of MRCP detection, and can guide selectively ERCP, improve the therapeutic effect, and reduce its risk．
