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:


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


  • 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.

Primary Outcome Measures:
  • Patient comfort post ERCP [ Time Frame: 1 hour ] [ Designated as safety issue: No ]
    the pain score measures using Visual Analog scale (VAs - 1 to 10 cm scale )

Secondary Outcome Measures:
  • Abdominal distention prior and post ERCP [ Time Frame: 5 minutes ] [ Designated as safety issue: No ]
    The abdominal girth was measured prior to patient shifted to ERCP table. The immdiately post ERCP the abdominal girth measured. A fixed point is marked at the umblical regiem to maintain the site of abdominal girth.
