S0293 Co2 Insufflation vs Air Insufflation for Elective Colonoscopy at Two Reference Centers in Ecuador

Abstract:

METHODS: Prospective analytical cohort study from July 2018 to February 2020, 876 colonoscopy examinations were randomized into two groups according to the gas insufflation used: Air Group (n= 460) and CO 2 Group (n= 416). RESULTS: The Air and CO 2 Groups were similar in respect to bowel preparation evaluated using the Boston scale, no statistically significant differences related to reasons for examination, presence or intensity of pain at the time of the procedure, age, gender, previous surgery, maneuvers necessary for the advancement of the device, and presence of polyps, tumors or signs of diverticulitis, sedation dosage, complications. The relative risk (RR) of immediate pain is 4.6 times higher when insufflation is done with air instead of CO 2 (RR= 4.6; 95% CI: 3.2–8.1; P< 0.001). The risk of abdominal distension in the air group was 2.4 times higher than that of the group insufflated with CO 2 (RR= 2 …
