[Explosion in rectum].
The article describes a case of gas explosion during diathermy snare resection of a polyp in the rectum, after cleansing with a sorbitol enema. Proximity to anus prevented perforation or other complications. The patient was shown to be a methane producer by a hydrogen-methane breath test. Gas explosion is a rare complication during use of diathermy in lower endoscopy, and usually occurs in patients with sub-optimal bowel cleansing. CO2 insufflation will prevent this and should be the method of choice; first of all because it reduces patient discomfort in the period after colonoscopy.
