Brief Summary:
Comparison on the effect on patient pain and discomfort by using CO2 instead of air for insufflation during gastroscopy.

Condition or disease Intervention/treatment Phase
Pain Procedure: CO2 insufflation Not Applicable

Detailed Description:

To achieve a satisfactory examination of the GI tract it needs to be distended during endoscopic procedures. After the examinations many patients complain of abdominal pain and discomfort. This pain has been substantially reduced by substituting room air with CO2 in both colonoscopies and ERCPs. The use of CO2 during colonoscopy has become routine practice at many endoscopy centers.

In our study we will test the hypothesis that abdominal pain after gastroscopies also can be reduced by substituting room air with CO2.

Arm Intervention/treatment
No Intervention: Room air insufflation
Air used for insufflation during gastroscopy to expand the lumen for inspection of the mucosal lining. This is current standard procedure, i.e. no experimental intervention.
Experimental: CO2 insufflation
CO2 used for insufflation during gastroscopy to expand the lumen for inspection of the mucosal lining. This is not standard procedure and therefore experimental intervention.
Procedure: CO2 insufflation
From the CO2 rack through the endoscopy rack CO2 will be insufflated to visualize the mucosa during oesophagogastroduodenoscopy.

Primary Outcome Measures :
  1. Pain after OGD [ Time Frame: 0-48 hours ]

Secondary Outcome Measures :
  1. Pain during OGD [ Time Frame: 24 hours ]
