There are ample data indicating that use of CO2 insufflation during many types of endoscopic procedures is associated with less postprocedural pain compared with air insufflation. CO2 insufflation offers clear benefits to patients undergoing advanced endoscopic procedures, lengthy endoscopic procedures, and unsedated procedures. In addition, CO2 insufflation offers significant potential benefit to patients undergoing endoscopic procedures associated with higher risks of perforation or of gas embolism. Standard endoscopy systems marketed by all major manufacturers support air insufflation. Development of endoscopy systems with integrated CO2 insufflators may decrease the barriers to more widespread adoption of CO2 as an insufflation agent during endoscopy.
