    Abstract:
    BACKGROUND AND AIM: Looping is a major problem in colonoscopy, and it prolongs procedure time. We evaluated the efficacy and safety of an external abdominal compression device (back brace support belt; Maxbelt) with respect to cecal insertion time and other outcomes. METHODS: We performed a prospective study on outpatients undergoing elective colonoscopy in Toyoshima Endoscopy Clinic. Subjects were randomly assigned to groups and were subjected to either Maxbelt (n = 39) or no device (control, n = 38) during colonoscopy. The colonoscopist was blinded to the study. The primary outcome that was observed was insertion time. RESULTS: The intubation time of the Maxbelt group was shorter than that of the no device group, but the difference was not significant (3.29 vs 4.49 min, P = 0.069). After stratifying by age, the use of Maxbelt significantly decreased cecal intubation time in elderly participants (age ≥ 45) compared to no device group (3.27 vs 5.00 min, P = 0.032). The use of the Maxbelt significantly decreased insertion difficulty encountered by the colonoscopist (P = 0.01). There was no difference in adenoma detection rate, manual pressure, position change, and adverse event. CONCLUSIONS: The use of a back brace support belt could be a viable approach for colonoscopy in elderly patients. (University Hospital Medical Information Network: UMIN000029361).
