Abstract:Objective To evaluate the efficacy and safety of a China‑made disposable peroral cholangioscope in animal cholangioscopy. Methods Six healthy Bama minipigs underwent the domestic disposable peroral cholangioscopy after anesthesia. The operation performance and image quality of the products were evaluated, and intraoperative and postoperative complications were recorded. Results All 6 animals received the domestic disposable peroral cholangioscopy. The cholangioscope showed good operating performance and could smoothly enter the biliary tract through the duodenoscope. The water injection, suction and instrument channels were unobstructed. The cholangioscopic image was clear, the color resolution was good, and there was no image distortion. The lumen and the mucosal surface could be accurately assessed. During the examination, there was no operative injuries such as bleeding, perforation, or adverse events such as respiratory depression or cardiac arrest. All pigs survived the operation with no adverse reaction. Conclusion The China-made disposable peroral cholangioscope is safe, with good operability and high‑quality image.
