    Cholangioscopy-assisted ERCP significantly reduced median radiation exposure compared to conventional fluoroscopy-guided ERCP (9.93 vs. 14.64 mGy, p < 0.001).

  • 2

    After IPTW adjustment, cholangioscopy assistance was linked to a lower risk of high radiation exposure (risk ratio 0.301, p = 0.042).

  • 3

    Procedure time and hospitalization costs were higher for cholangioscopy-assisted ERCP, while the length of stay was shorter compared to conventional ERCP.

  • 4

    Complete duct clearance in one session was achieved in 88.0% of cholangioscopy-assisted cases versus 94.0% in the conventional group.

  • 5

    No significant differences in short-term adverse events were observed between cholangioscopy-assisted and conventional ERCP groups.
