Biliary strictures that remain unclassified after cross-sectional imaging and endoscopic retrograde cholangiopancreatography-based tissue sampling are defined as indeterminate biliary strictures (IDBS). A substantial proportion of biliary strictures fall into this category due to low sensitivity of brush cytology and intraductal biopsy. Over last few decades, several modalities have emerged for the evaluation of IDBS. Of these, cholangioscopy and endosonography are the frontrunners and have cemented their place for the evaluation of IDBS. Both of these modalities are widely available, and therefore, biliary strictures that remain uncharacterized after their utilization represent IDBS in the current era.
经影像学检查和内镜逆行胰胆管造影（ERCP）下组织采样后仍无法分类的胆管狭窄被定义为不确定型胆管狭窄（IDBS）。由于刷检细胞学和胆管内活检的敏感性较低，相当一部分胆管狭窄属于这一范畴。在过去几十年中，已经出现了多种方法来评估 IDBS。其中，胆管镜检查和超声内镜检查是领先的方法，已经为 IDBS 的评估奠定了基础。这两种方法都广泛应用，因此，在使用这些方法后仍未明确特征的胆管狭窄在当前时代被认为是 IDBS。
