Colonoscopy using back brace support belt: A randomized, prospective trial

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).

Effects of Encircled Abdominal Compression Device in Colonoscopy: A Meta-Analysis

“…However, the subgroup analysis revealed that ColoWrap ® significantly reduced the caecal intubation time in obese patients (body mass index of 30-40). Toyoshima et al reported that the encircling the abdominal compression device (Maxbelt ® ) did not significantly decrease the caecal intubation time [7]. However, the subgroup analysis revealed that the Maxbelt ® significantly reduced the caecal intubation time in patients of higher age (age ≥ 45).…”

“…However, Crockett et al reported inconsistent results [5]. Recently, we conducted an RCT to determine the efficacy and safety of an encircling abdominal compression device (back brace support belt: Maxbelt Ⓡ ) [7]. The intubation time in the Maxbelt group was shorter than that in the control group, but the difference was not significant (3.29 vs. 4.49 min, p = 0.069).…”

“…Alternatively, a corset to encircle the abdomen might exert a well-balanced and effective pressure for the entire duration of the colonoscopy (Figure 1). Several randomized controlled trials (RCTs) have investigated the efficacy of encircling abdominal compression devices in colonoscopies [5][6][7][8][9]. Toros et al and Yu et al showed that encircling abdominal compression devices significantly reduced the caecal intubation time [6,9].…”

“…This systematic review was performed following Cochrane Handbook for Systematic Reviews of Interventions. 12 The study was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 15 …”
