N2 - Background: Successful cannulation of the common bile duct (CBD) remains the benchmark for ERCP. Use of a pancreatic duct (PD) stent to facilitate biliary cannulation has been described, although the majority of patients require precut sphincterotomy to achieve CBD cannulation. Objective: To report the performance characteristics of using a PD stent in conjunction with physician-controlled wire-guided cannulation (WGC) to facilitate bile duct cannulation. Design: Retrospective cohort. Setting: Two tertiary care, academic medical centers. Patients: All undergoing ERCP with native papillae. Intervention: In cases of difficult biliary access in which the PD is cannulated, a pancreatic stent is placed. After this, physician-controlled WGC is attempted by using the PD stent to direct the sphincterotome into the biliary orifice. If cannulation is unsuccessful after several minutes, a precut sphincterotomy is performed over the PD stent or the procedure is terminated. Main Outcome Measurements: Frequency of successful bile duct cannulation and precut sphincterotomy. Results: A total of 2345 ERCPs were identified, 1544 with native papillae. Among these, CBD and PD cannulation failed in 16 (1.0%) patients, whereas 76 (4.9%) patients received a PD stent to facilitate biliary cannulation. Successful cannulation was achieved in 71 (93.4%) of 76 patients, 60 (78.9%) of whom did not require precut sphincterotomy. Complications included mild post-ERCP pancreatitis in 4 (5.3%) and aspiration in 1 (1.3%). Precut sphincterotomy was complicated by hemorrhage, controlled during the procedure in 2 (13.3%) of 15. Conclusions: Physician-controlled WGC over a PD stent facilitates biliary cannulation while maintaining a low rate of precut sphincterotomy.
