The risks associated with the ERCP procedure will be explained to patients who meets the eligibility criteria. Consenting patients will be randomized to undergo Endoscopic retrograde cholangiopancreatography (ERCP) using either (1) a duodenoscope with a Single-use distal cover or (2) a conventional reusable duodenoscope. Assessments will be made during, and immediately after the procedure, then patients will be called after 1 week, 1 month, and 3 months after the procedure to get information about adverse events.
