Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	A complete common bile duct accessing rate	To test the device's feasibility	1 day
Primary	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).	1 day
Secondary	Number of complications (ablation, bleeding, perforation in percentage) or system malfunction	To test the device's safety	1 day
Secondary	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)	1 day
Secondary	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.	1 day
