Wire-guided cannulation (WGC) during endoscopic retrograde cholangiopancreatography (ERCP) is a selective biliary cannulation technique aimed at improving the successful selective biliary cannulation rate and reducing the rate of post-ERCP pancreatitis (PEP) incidence. This study aimed to evaluate the effectiveness of angled-tip guidewires (AGW) vs. straight-tip guidewires (SGW) for biliary cannulation via WGC by a trainee.
We conducted a prospective, single-center, open-labeled, randomized, and controlled trial. Fifty-seven patients were enrolled in this study and assigned randomly to two groups (Group A to S and Group S to A). In this study, we started selective biliary cannulation via WGC with an AGW or an SGW for 7 min. If cannulation was unsuccessful, the other guidewire was used, and cannulation was continued for another 7 min (cross-over method).
The selective biliary cannulation success rate over 14 min was significantly higher with an AGW compared with an SGW over 14 min (57.8% vs. 34.3%, = 0.04) and for the second 7-min segment (36.4% vs. 0%, = 0.04). No significant difference was found for adverse events such as pancreatitis between the two guidewires.
Our results suggest that an AGW is recommended for WGC performed by a trainee.
内镜逆行胰胆管造影术（ERCP）期间的导丝引导插管（WGC）是一种选择性胆管插管技术，旨在提高选择性胆管插管成功率并降低ERCP术后胰腺炎（PEP）的发生率。本研究旨在评估新手通过WGC使用弯头导丝（AGW）与直头导丝（SGW）进行胆管插管的有效性。
我们进行了一项前瞻性、单中心、开放标签、随机对照试验。57例患者纳入本研究并随机分为两组（A至S组和S至A组）。在本研究中，我们通过WGC使用AGW或SGW开始选择性胆管插管7分钟。如果插管不成功，则使用另一根导丝，并继续插管7分钟（交叉法）。
与14分钟内使用SGW相比，14分钟内使用AGW的选择性胆管插管成功率显著更高（57.8%对34.3%，P = 0.04），且在第二个7分钟时间段内也是如此（36.4%对0%，P = 0.04）。两种导丝在胰腺炎等不良事件方面未发现显著差异。
我们的结果表明，推荐新手在WGC中使用AGW。
