Summary
Brief summary (as posted)
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.
