Core Tip
Core tip: Pancreatitis is one of the most common and severe complications after endoscopic retrograde cholangiopancreatography (ERCP). The reported incidence of post-ERCP pancreatitis (PEP) varies between 2% and 7% in prospective trials and may be as high as 30%-50% in high-risk patients. Although a previous meta-analysis has indicated that pancreatic duct stent placement can prevent PEP, particularly in high-risk patients, there is a lack of high-quality evidence-based studies based on appropriate numbers of well-validated publications. Therefore, an updated meta-analysis was conducted to investigate stents in preventing PEP.
