It will also learn about the safety of the low-wattage holmium laser. The main questions it aims to answer are:\n\nIs the low-power holmium laser effective at treating large and\u002For 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\u002For difficult bile duct or pancreatic duct stones.\n\nParticipants will:\n\nUndergo 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.\n\nAnswer a call 30 days after the procedure to document symptoms and\u002For any side effects.",[27,28],"Choledocholithiasis","Pancreatic Duct Stone",[30,31,32],"Laser lithotripsy","choledocholithiasis","pancreaticolithiasis","RECRUITING","2026-02-17",{"date":36,"type":37},"2026-02-18","ACTUAL",{"date":39,"type":37},"2026-01-15",{"date":41,"type":21},"2027-12",{"name":43,"class":44},"Rush University Medical Center","OTHER"]
