Brief summary

The purpose of this study it to conduct a randomized, controlled, double-blinded trial of carbon dioxide (CO2) versus air insufflation during endoscopic retrograde cholangiopancreatography (ERCP).

Interventions

The bowel lumen will be insufflated with CO2 during the endoscopy (as compared to room air).

During the ERCP, room air will be insufflated (current standard clinical practice) as a placebo comparator.
