Randomized Controlled Trial Multicenter Study
CO2 insufflation during single-balloon enteroscopy: a multicenter randomized controlled trial.
Carbon dioxide (CO2) insufflation has previously been shown to have advantages over air insufflation in terms of procedure-related pain and oral insertion depth during double-balloon enteroscopy. The aim of this prospective study was to evaluate the performance of CO2 vs. air insufflation during single-balloon enteroscopy. ⋯ This study demonstrated an advantage of using CO2 insufflation during single-balloon enteroscopy in patients with a history of previous abdominal surgery. Overall, single-balloon enteroscopy was a well-tolerated procedure that may benefit from the use of CO2 insufflation to reduce post-procedural pain.
