Study summary

A disposable endoscopy system (NCKU-scope-01) was developed for the evaluation of bile duct stone or neoplasm. This system consists of a camera, light sources, a working channel, and a water injection channel. The endoscope could be inserted into the common bile duct via the working channel of a commercial duodenoscope. This study aims to test the feasibility and safety of this system. The efficacy of stone and neoplasm diagnosis will also be analyzed.

What researchers measure

Primary outcomes

  1. A complete common bile duct accessing rate

    To test the device's feasibility

    Time frame: 1 day

  2. Image quality evaluation: the light brightness and the imaging sharpness in Likert scale

    To test the device's feasibility. About Likert scale, it range from 1 to 5 (1 is worse and 5 is better).

    Time frame: 1 day

Secondary outcomes

  1. Number of complications (ablation, bleeding, perforation in percentage) or system malfunction

    To test the device's safety

    Time frame: 1 day

  2. In biliary stone arm: The biggest residual stone size (in cm).

    The ability for residual stones diagnosis after initial ERCP stone extraction, compared with standard x-ray imaging)

    Time frame: 1 day

  3. In biliary stricture arm: Number of the lesions with or without presenting of the specific features for DDx of the benign or malignant stricture

    The ability for differential diagnosis of benign or malignant stricture. The specific features include increased vascularity, irregular mucosa/nodularity, luminal narrowing, tumor vessel, mucosal lesion.

    Time frame: 1 day
