Outcome of Carbon Dioxide Versus Air Insufflations During Endoscopic Retrograde Cholangiopancreatography (ERCP)

A Double-blind, Randomized, Controlled Trial of Air Insufflation Versus Carbon Dioxide Insufflation During Endoscopic Retrograde Cholangiopancreatography (ERCP).

To assess the safety and efficacy of CO2 insufflations during ERCP

1. Primary objective:

   To assess the patient's symptoms, abdominal pain and abdominal distension post procedure (ERCP) in the study group.

2. Secondary objective:

Endoscopist:

• To assess the adequacy of bowel distension for adequate luminal visualization
• To assess the peristaltic movement during the ERCP

Anesthetist:

• To measure the PCO2 level in patient post procedure.
• To assess the amount of sedation required during the procedure.
• To assess saturation and vital signs through out the procedure.
• To assess requirement of buscopan.
