BACKGROUND AND STUDY AIMS: In difficult cases of selective bile duct cannulation, several expanded techniques are available which have only been partially evaluated in randomized studies. This study describes a prospective, randomized trial investigating a further technique for obtaining selective biliary access--pancreatic duct wire placement.
PATIENTS AND METHODS: During a six-month study period, 107 consecutive patients required deep selective biliary cannulation. Accessing the bile duct using a catheter failed within 10 min in 53 of the patients, who were randomly assigned to either pre-insertion of a guide wire into the pancreatic duct or persistence with a conventional catheter. The success rate and complication rate were compared between these two groups.
RESULTS: In the pancreatic duct-guide wire group (n=27), the success rate was significantly greater than in the conventional group (93% vs 58%). No pancreatitis complications occurred within either group.
CONCLUSIONS: Inserting a guide wire into the pancreatic duct to facilitate deep selective bile duct cannulation is better than persisting with a conventional catheter. Further studies will be needed to confirm these results and to compare this method with other sophisticated techniques for obtaining selective access to the bile duct.
