Abstract
This Expression of Concern is issued in regards to the article by Ladas et al, titled “Colonic gas explosion during therapeutic colonoscopy with electrocautery”, published in the World Journal of Gastroenterology (WJG) in 2007 (https://dx.doi.org/10.3748/wjg.v13.i40.5295). Concerns have been raised about whether the article’s recommendation to avoid bowel preparation agents containing poorly absorbed carbohydrates, such as mannitol or sorbitol, was adequately supported by the cited evidence. Following an editorial review of the concerns and the relevant references, the WJG Editorial Office found that some of the cited cases do not appear to involve mannitol- or sorbitol-containing preparations in the manner stated or implied in the article. Because these issues may affect readers’ interpretation of the article’s conclusions regarding bowel preparation and colonic gas explosion risk, this Expression of Concern is published as an alert to readers.
Core Tip: A reader raised concerns that the conclusion of the article “Colonic gas explosion during therapeutic colonoscopy with electrocautery”, published in the World Journal of Gastroenterology in 2007, may not have been supported adequately by the cited evidence, and may affect readers’ interpretation of bowel preparation risks. After reviewing the relevant references, the Editorial Office found that some cited cases do not appear to support this conclusion as presented. Therefore, this Expression of Concern is issued to alert readers and to recommend cautious interpretation of the relevant conclusions.
