Risks associated with use of anesthesia during colonoscopy

By: Judy Mathias

Editor's Note

The overall risk of complications after colonoscopy increases when patients receive anesthesia, this study finds.

The use of anesthesia was associated with a 13% increase in complications within 30 days, including a higher risk of perforation, hemorrhage, and abdominal pain. The risk of perforation was 26% higher in patients who had anesthesia and at least one polyp removed.

Widespread adoption of anesthesia for colonoscopy should be considered within the context of all potential risks, the authors note.
