经内镜逆行胰胆管造影术后胰腺炎预防策略研究进展

经内镜逆行胰胆管造影术（endoscopic retrograde cholangiopancreatography，ERCP）已成为诊治胆胰系统疾病的主要手段。在ERCP介入治疗越来越多的趋势下，术后不良事件发生率也呈上升趋势。其中，ERCP术后胰腺炎（post-ERCP pancreatitis，PEP）是最常见的术后并发症，严重时甚至会威胁患者生命，并使得ERCP广泛开展受到一定困扰。如何有效预防和降低该并发症发生是目前临床研究的热点和难点。本文对PEP的定义、发病机制、危险因素和预防措施的研究现状进行综述，并对其优化的预防策略进行概括和总结。

Research advances in prevention strategy for post endoscopic retrograde cholangiopancreatography pancreatitis

Endoscopic retrograde cholangiopancreatography (ERCP) has been a mainstay examination to clarify the biliary and pancreatic system. Under the trend of more and more procedures about ERCP being interventional, the rate of adverse events after the procedure is increasing. Among them, post-ERCP pancreatitis (PEP) is the most common and sometimes tremendous complication, which limits the wide use of ERCP. This mini-review will overview the PEP from definition, pathogenesis, risk factors to prevention, and summarized the optimal prevention strategy.
