Intracolonic explosion

An intracolonic explosion or colonic gas explosion is an explosion inside the colon of a person due to ignition of explosive gases such as methane. This can happen during colonic exploration, as a result of the electrical nature of a colonoscope.

A colonic gas explosion is rare; however, the result can be acute colonic perforation, which can be fatal.

Cause
An explosion is triggered by a combination of combustible gases such as hydrogen or methane, combustive gas such as oxygen, and heat. An explosion can also be caused by Crohn's disease.

Prevention
Careful bowel preparation, such as cleansing the colon before a procedure, is key to preventing an intracolonic explosion.
