Question: Question: Is cannulation time a more accurate measure of cannulation difficulty in endoscopic retrograde cholangiopancreatography than the number of attempts?
Answer: The grade of cannulation difficulty for a given ERCP procedure may differ when different methods are used (total cannulation time vs number of attempts); thus, grading by different methods should not be used interchangeably.

Answer:
yes
