Abstract: Abstract: Endoscopic retrograde cholangiopancreatography (ERCP) is the most challenging technique of gastrointestinal endoscopy. Patients are most likely to benefit from this mini invasive treatment, meanwhile they bear high risk of complications, which might be life-threatening. Standard operation, standardized training, quality control and whole-process management of perioperative period are critical factors for ERCP training, and should be popularized in medical centers, where ERCP are performed. This paper has illustrated the whole-process management of perioperative period for ERCP, including preoperative preparation, decision-making during operation, postoperative management, as well as prevention and treatment of complications. By performing whole-process management of ERCP, patient can benefit more from ERCP operation, and which will serve more patients

Key words: cholangiopancreatography, endoscopic retrograde, intraoperative period, whole-process management
