Abstract
- Aim: To investigated the hemostatic ability of the S and F1-10 methods in clinical and ex vivo studies.<br />Methods: The hemostatic abilities of the two methods were analyzed retrospectively in all six gastric endoscopic submucosal dissection cases. The treated vessel diameter, compressed vessel frequency, and bleeding frequency after cutting the vessels were noted by the recorded videos. The coagulation mechanism of the two power settings was evaluated using the data recording program and histological examination on macro- and microscopic levels in the ex vivo experiments using porcine tissues.<br />Results: F1-10 method showed a significantly better hemostatic ability for vessels ≥ 2 mm in diameter and a trend of overall better coagulation effect, evaluated by the bleeding rate after cutting the vessels. F1-10 method could sustain electrical current longer and effectively coagulate the tissue wider and deeper than the S method in the porcine model.<br />Conclusion: F1-10 method is suggested to achieve a stronger hemostatic effect than the S method in clinical procedures and ex vivo models.<br />Competing Interests: Conflict-of-interest statement: Toyonaga T invented the FlushKnife-BT in conjunction with Fujifilm and received royalties from its sale; Ishida T, Ohara Y, Nakashige T, Kitamura Y, Ariyoshi R, Takihara H, Baba S, Yoshizaki T, Kawara F, Tanaka S, Morita Y, Umegaki E, Hoshi N, and Azuma T have no conflicts of interest or financial ties to disclose.
