When electrocautery is used through the colonoscope, there is a risk of gases normally present in the colon causing an explosion. These gases, such as methane and hydrogen, can be ignited by the electrical current used in electrocautery. Therefore, it is important to have carbon dioxide available to flush out the colon and replace these potentially explosive gases. This ensures safety during the procedure. Additionally, good visibility is important during the procedure, but the main reason for having carbon dioxide available is to prevent the risk of explosion.Rate this question:
