CO2 Insufflation vs. Air Insufflation in Enteroscopy

Share on Facebook
In a recent study published in the journal Gut, researchers compared insufflation rates using air and carbon dioxide. The study was designed to determine whether or not carbon dioxide increases the total enteroscopy rate and intubation rate of single-balloon enteroscopy.

The study found intubation in the CO2 group was superior in both the oral and anal routes. The total enteroscopy rate in the CO2 group was 34.9 percent, compared to 17.6 percent in the air group.

The researchers concluded that CO2 insufflation results in improved intubation depth and total enteroscopy rate.
