Randomized Trial of Wire and Sphincterotome Systems for Biliary Cannulation
Cholestasis, Extrahepatic
About this trial
This is an interventional treatment trial for Cholestasis, Extrahepatic focused on measuring cholangiopancreatography, endoscopic retrograde
Eligibility Criteria
Inclusion Criteria:
- Undergoing ERCP at LAC+USC Medical Centers for standard indications including bile duct stones, bile leak, and biliary obstruction will be included.
Exclusion Criteria:
- Prior ERCP with sphincterotomy
- Prior ERCP with failed bile duct cannulation
- Pregnant, imprisoned, under age 18, unable to give informed consent
- Prior biliary diversion surgery will be excluded
- Those who require ERCP only for pancreatic duct indications will also be excluded as bile duct cannulation is not clinically necessary in this group
