Right Upper Quadrant Pain Following Endoscopic Retrograde Cholangiopancreatography; a Case Report

Endoscopic retrograde cholangiopancreatography (ERCP) is a standard for diagnosing and treating hepato-pancreatico-biliary (HPB) diseases in clinical settings. ERCP-related complications are relatively common, rang-ing from 4 to 30%. The most common one is acute pancreatitis. ERCP-related necrotizing pancreatitis accountsfor 7.7% of ERCP-related pancreatitis cases. This complication may still be misdiagnosed, which might lead toinappropriate treatment with a worse prognosis. Here, we report a 34-year-old case with ERCP-related necrotiz-ing pancreatitis who was successfully managed, but initially misdiagnosed with biliary peritonitis.
