In ERCP, precutting is used when biliary cannulation is challenging. Precutting is a high-risk procedure that can lead to adverse events. TeXture and color enhancement Imaging (TXI) enhances texture, brightness, and color to define subtle tissue differences clearly and may be helpful in precutting. Nevertheless, there are limited video case reports demonstrating precutting using TXI. Here, we review the techniques of TXI-assisted precutting.
This video article describes TXI-assisted precutting in 3 patients with obstructive jaundice resulting from cancer of the pancreatic head. The existing literature on TXI for biliopancreatic endoscopy also is reviewed.
In all cases, TXI helped in biliary cannulation using precutting. No adverse events were observed in any of the cases.
Despite the roughness of the precut incision surface, TXI was found to improve visibility and significantly helped achieve biliary cannulation.
在经内镜逆行胰胆管造影（ERCP）中，当胆管插管困难时会采用预切开术。预切开术是一种高风险操作，可能导致不良事件。组织纹理和色彩增强成像（TXI）可增强纹理、亮度和色彩，从而清晰界定细微的组织差异，可能有助于预切开术。然而，仅有有限的视频病例报告展示了使用TXI进行预切开术的情况。在此，我们回顾TXI辅助预切开术的技术。
本文通过视频介绍了3例因胰头癌导致梗阻性黄疸患者的TXI辅助预切开术。同时也回顾了关于TXI用于胆胰内镜检查的现有文献。
在所有病例中，TXI均有助于通过预切开术实现胆管插管。所有病例均未观察到不良事件。
尽管预切开的切口表面粗糙，但TXI仍能提高视野清晰度，并显著有助于实现胆管插管。
