内镜逆行胰胆管造影(ERCP)显示导管病变行细胞刷诊断恶性病变是可靠的方法。可是,以往报道病例数少。本文报道69例 ERCP 细胞刷诊断结果。其中62例(90%)患者取得满意标本.确诊的总敏感度为44%,而特异性达100%。胆总管刷高于胰腺刷的敏感性。36%的患者鉴定有显著的非典型细胞,但细胞刷诊断呈假阴性结果,而良性病变患者无此发现。检查后有2例患者发生轻度胰腺炎,另1例发生胆管炎,但细胞刷对导致这些并发 Endoscopic retrograde cholangiopancreatography (ERCP) is a reliable method for diagnosing malignant lesions by catheter brushing. However, there have been few reported cases. This article reported 69 cases of ERCP cell brush diagnosis. Of these, 62 (90%) patients had satisfactory specimens. The total sensitivity of diagnosis was 44%, and the specificity was 100%. Common bile duct brush is more sensitive than pancreatic brush. Thirty-six percent of patients identified significant atypical cells, but cytobrush diagnosis showed false negative results, whereas patients with benign lesions did not have this finding. There were 2 cases of mild pancreatitis and 1 case of cholangitis after the examination, but the cell brush resulted in these concurrent
