BACKGROUND:ERCP can be associated with serious complications. Difficulty in common bile duct (CBD) cannulation is one of the main risk factors for post-ERCP pancreatitis. The double-guidewire technique (DGT) has been considered a promising alternative approach in difficult cannulation situations. OBJECTIVE: To compare the performance of DGT with the standard cannulation technique (SCT) in patients in whom CBD cannulation is difficult to perform. DESIGN: Multicenter randomized, controlled trial. SETTING:Six tertiary referral centers. PATIENTS: A total of 188 patients with difficult CBD cannulation defined by completion of 5 unsuccessful cannulation attempts were enrolled. INTERVENTIONS:Ninety-seven patients were assigned to the DGT group and 91 to the SCT group. Both techniques were compared for an extra 10 cannulation attempts. MAIN OUTCOME MEASUREMENTS: CBD cannulation rate, number of attempts required to cannulate, and ERCP-related complications. RESULTS:Successful CBD cannulation was achieved in 46 of 97 (47%) patients in the DGT group compared with 51 of 91 (56%) in the SCT group (OR 0.85; 95% CI, 0.64-1.12). The median number of attempts required for each group was 9 and 7, respectively (P = .128). The incidence of post-ERCP pancreatitis was 17% in the DGT group and 8% in the SCT group (OR 2.13; 95% CI, 0.89-5.05). LIMITATIONS: Reduced number of enrolled subjects and a lack of detailed information regarding the number and extent of pancreatic duct contrast injections. CONCLUSIONS: In patients with difficult CBD cannulation, DGT was not superior to SCT in achieving CBD cannulation. DGT might be associated with a higher risk of post-ERCP pancreatitis.
