Comparison of endoscopic band ligation devices used for colonic diverticular bleeding : in vivo animal study
© 2020 The Authors. JGH Open published by Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd..
BACKGROUND AND AIM: Endoscopic band ligation (EBL), used for the treatment of colonic diverticular bleeding, has a lower rebleeding rate than endoscopic clipping. However, different devices are used in Japan and the Western countries; no animal studies have been conducted to elucidate the safety of such devices. We compared two EBL devices, the first used in Japan and the second used in Western countries.
METHODS AND RESULTS: The Japanese and Western EBL devices were compared by assessing the EBL safety at 40 sites in an animal model with a normal colon that is anatomically similar to the human colon. Macroscopic and pathological examinations were performed to evaluate the layer ligated by the band and the presence of perforation. The findings on day 1 and day 7 after EBL were compared. The ligated layer was the muscularis propria at 39 sites; the layer was not evaluated at one site where the band was unintentionally removed during the endoscopic procedure. Pathologically, there was no perforation at any of the assessed sites. There was no statistical difference in any of the pathological variables between the two devices or between days 1 and 7 after EBL. The total procedure time was significantly shorter with the Western EBL device.
CONCLUSIONS: In this animal study, both evaluated devices were safe for EBL, without differences in the macroscopic and pathological variables after EBL. Ligation of the muscularis propria layer did not result in perforation.
