Pancreatic Duct Stone

The goal of this clinical trial is to learn if a low-power holmium laser works to treat large and/or difficult bile duct or pancreatic duct stones in adults. It will also learn about the safety of the low-wattage holmium laser. The main questions it aims to answer are: Is the low-power holmium laser effective at treating large and/or difficult bile duct or pancreatic duct stones? Is the low-power holmium laser effective safe to use in adults? How does the low-power holmium laser compare to electrohydraulic lithotripsy for the management of large and/or difficult bile duct or pancreatic duct stones. Participants will: Undergo ERCP procedure and their bile duct or pancreatic duct stone will either be broken up with the low-power holmium laser lithotripsy device or the electrohydraulic lithotripsy lithotripsy device. Answer a call 30 days after the procedure to document symptoms and/or any side effects.
