Arms Assigned Interventions
experienced assistant group
experienced endoscopist with an experienced assistant.
Procedure: Team 1
experienced endoscopist with a experienced assistant
Other Name: experienced
new trained assistant group
same experienced endoscopist with a new trained assistant
Procedure: Team 2
same experienced endoscopist with a new trained assistant
Other Name: new trained

Detailed Description:
A new single-operator wire-guided cannulation technique was performed on all patients. All procedures were performed by the same experienced endoscopist, but with different assistants in two groups (with an experienced one in Group A, and a new trained one in Group B). The number of attempts at cannulation, cannulation time, success rate, and procedure-related complications were compared between the two groups.
