Efficacy of forced coagulation with low high-frequency power setting during endoscopic submucosal dissection

Table 2 Results of the vessel diameter, frequency of the compressed vessel, and coagulation time in the vessel-sealing with endoknife compression technique during gastric endoscopic submucosal dissection

	S method	F1-10 method	P1 value
Number of vessels processed by vessel-sealing	49	62
with endoknife compression
Median vessel diameter (mm) (range)	2 (1-3)	1.5 (1-3)	0.68
Median frequency of compressed vessel (times) (range)	2 (1-8)	2 (1-5)	0.11
Median time of coagulation (s) (range)	9 (2-48)	10 (1-58)	0.11

¹Continuous variables were compared using the Wilcoxon's rank-sum test.
