Carbon Dioxide Versus Air Insufflation in Oesophago-gastro-duodenoscopy (OGD)
Carbon Dioxide Versus Air Insufflation in Oesophago-gastro-duodenoscopy (OGD)
Comparison on the effect on patient pain and discomfort by using CO2 instead of air for
 insufflation during gastroscopy.
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.
