abstract: Incontinence after colonoscopy - an unrecognized and preventable problem. A cross-sectional study from the Gastronet quality assurance program

 Abstract

"Female patients had a higher risk of incontinence than men."

Background: 
Colonoscopy requires insufflation of gas for visualization of the bowel wall. Worldwide, this is usually done using air. The aim of the present study was to assess the risk of post colonoscopy incontinence, and to investigate whether insufflation of CO₂ instead of air may reduce this risk, since it is easily absorbed through the bowel mucosa.
 

Conclusion:
About every 20th patient undergoing colonoscopy using standard air insufflation experiences post examination incontinence. This proportion can be reduced by 60 % by converting from air insufflation to insufflation with the absorbable CO₂.
