Objective:

To evaluate the diagnostic value and safety of peroral cholangioscopy (POCS) combined with modified biopsy forceps for malignant biliary strictures (MBS).

Approach:
    Key Findings:
    • Biliary strictures can be benign or malignant, with misdiagnosis leading to unnecessary surgical interventions.
    • POCS allows for direct visualization and targeted biopsy, improving diagnostic accuracy for MBS.
    • Modified biopsy forceps were developed to enhance access and sampling capability during POCS.
    Interpretation:

    Limitations:
    • Retrospective design may introduce bias.
    • Single-center studies may limit generalizability.
    Conclusion:
