Sampling at ERCP may be performed at the level of the papilla or of the biliopancreatic ducts. Samples collected at the level of the biliopancreatic ducts allow for diagnosing malignancy with a specificity close to 100% but present a moderate sensitivity in most studies. In this article, the different aspects of sampling at ERCP are discussed, and a special focus is placed on the means that are routinely available to the endoscopist for obtaining a high sensitivity for the diagnosis of malignancy.
内镜逆行胰胆管造影（ERCP）采样可在乳头或胆胰管水平进行。在胆胰管水平采集的样本诊断恶性肿瘤的特异性接近100%，但在大多数研究中敏感性中等。本文讨论了ERCP采样的不同方面，并特别关注内镜医师常规可用的方法，以获得对恶性肿瘤诊断的高敏感性。
