Bedside score predicting retained common bile duct stone in acute biliary pancreatitis

Abstract BACKGROUND: Retained common bile duct (CBD) stone after an acute episode of biliary pancreatitis is of paramount importance since stone extraction is mandatory. AIM: To generate a simple non-invasive score to predict the presence of CBD stone in patients with biliary pancreatitis. METHODS: We performed a retrospective study including patients with a diagnosis of biliary pancreatitis. One hundred and fifty-four patients were included. Thirty-three patients (21.5%) were diagnosed with CBD stone by endoscopic ultrasound (US). RESULTS: In univariate analysis,
