Endoscopic retrograde cholangio-pancreatography (ERCP) is one of the primary procedural techniques used for diagnosing biliary and pancreatic diseases. Post-ERCP pancreatitis (PEP) is the most common complication of ERCP, which resulted in prolonged hospitalization and potential risk of patients' lives, especially in severe cases. Understanding the risk factors associated with PEP is of paramount importance for its prevention. Currently, recognized risk factors for PEP encompass both patient-related factors and ERCP procedure-related factors. By considering these risk factors, implementing appropriate preoperative, intraoperative, and postoperative interventions could effectively reduce the incidence of PEP. In this article, we concisely summarized the common risk factors and preventive methods for PEP, offering valuable insights for healthcare professionals in clinical practice.

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.
