Abstract

Background: Guidewire (GW) cannulation can reduce the risk of post-ERCP pancreatitis (PEP) by avoiding the opacification of the main pancreatic duct. Objective: To compare the effects of conventional contrast ERCP and GW cannulation of the common bile duct on the rate of PEP in low- and high-risk patients. Design: Prospective, comparative-intervention single-center study. Setting: Tertiary referral center. Patients: Patients with biliary disease with an intact papilla were prospectively examined by ERCP. Interventions: Biliary cannulation using a sphincterotome with contrast injection (ConI) or a hydrophilic GW without contrast injection. Main Outcome Measurements: Pancreatitis rate in the GW group and the contrast injection (ConI) group. Results: PEP occurred in 60 of 1249 patients (4.8%), 35 of 678 (5.2%) in the GW group and 25 of 571 (4.4%) in the ConI group (not significant). The overall rate of PEP was significantly higher in high-risk patients (12.2%) than in low-risk patients (3.5%) (P
