Carbon dioxide is absorbed much more rapidly than air when used for insufflation during colonoscopy, resulting in less postprocedure gas distention and pain. To evaluate whether these benefits translate into fewer postprocedure hospital admissions, investigators conducted a prospective cohort study of patients undergoing resection for sessile colorectal lesions ≥2 cm at a single tertiary center.
Air was used for insufflation during the first few years of the study, followed by a conversion to use of carbon dioxide. Of 524 patients, 334 underwent endoscopic resection of 347 lesions with air insufflation, and 190 patients underwent resection of 228 lesions with carbon dioxide insufflation. The overall rate of postprocedure admission was lower …
