Clinical Trial Summary

1. Background

- Advanced guidewires with a U-shaped tip could effectively cross the long or multi-occlusive segment smoothly and go into the distal outflow vessel.

- The guidewire looping technique is a safe and effective method for the recanalization of the occluded lesions in infrapopliteal vessels.

2. Objective - To compare the performance a loop-tipped guidewire with a straight-tipped guidewire in achieving successful deep biliary cannulation.

3. Design

- Prospective randomized trial.

4. Setting:

- Tertiary-care medical center

5. Patients

- This study will involve 192 patients with biliary diseases which require endoscopic retrograde cholangiopancreatography.

6. Intervention - Cannulation of bile duct by using a loop-tipped guidewire or a straight-tipped guidewire

7. Main outcome measurements - Compare the cannulation success rate, the duration of the cannulation, immediate and late complications.
