Outcome Measures

Primary Outcomes (1)

  • Abdominal pain (VAS).

    pre-procedure and up to 24 hours post-procedure.

Secondary Outcomes (1)

  • The extent of CO2 retention.

    Intra-procedure

Study Arms (2)

I

EXPERIMENTAL
Other: CO2 insufflation

II

PLACEBO COMPARATOR

Room air will be used for insufflation as the placebo comparator arm.

Other: Room air insufflation

Interventions

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

Also known as: Olympus XUCR manufacured by Olympus Medical.
I

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

II
