NCT05320497

Brief Summary

The transparent cap-assisted endoscope has the function of fixing field of view and increasing visual space. It has been widely used in gastrointestinal examination and treatment. In this study, the investigators intend to apply transparent cap-assisted choledochoscopy to endoscopic biliary tract exploration and biopsy to investigate whether transparent cap-assisted choledochoscopy can improve operability, visual field clarity, and biopsy accuracy.

Outcome Measures

Primary Outcomes (2)

  • The clearness of visual field

    The clearness of visual field was evaluated by the operating physician and was rated as "clear" or "not clear."

    Immediately

  • Intubation rates of bile duct ends, cystic duct openings, and left and right hepatic duct bifurcations

    Comparison of intubation rates between transparent cap SpyGlass and standard SpyGlass

    Immediately

Secondary Outcomes (1)

  • Biopsy accuracy

    1 week

Study Arms (1)

Transparent cap-assisted SpyGlass

EXPERIMENTAL

Add a transparent cap to the end of the SpyGlass choledochoscopy

Device: Transparent cap

Interventions

Add a self-made transparent cap (made by cutting a silicone drainage tube) to the end of the SpyGlass choledochoscope, and then perform routine choledochoscopy and biopsy operations
