Randomized Controlled Trial
Carbon dioxide insufflation improves the intubation depth and total enteroscopy rate in single-balloon enteroscopy: a randomised, controlled, double-blind trial.
The total enteroscopy rate of single-balloon enteroscopy (SBE) using air insufflation is not satisfactory, and whether carbon dioxide (CO2) insufflation increases the total enteroscopy rate of SBE is unknown. This randomised controlled trial aimed to determine whether CO2 insufflation facilitates the intubation depth and total enteroscopy rate of SBE. ⋯ CO2 insufflation improves the intubation depth and total enteroscopy rate in SBE with a good safety profile and acceptability compared with that of air, and thus is recommended for clinical utilisation.
