Comparison of treatment outcomes between grasping forceps assisted endoscopic resection and endoscopic submucosal dissection groups

	GF-ER	ESD	P value
Procedure time, min
Median (IQR)	4.0 (3.0-5.0)	55.0 (30-105)	< 0.01
En bloc resection, n (%)	9 (100)	63 (100)	1.0
R0 resection, n (%)	9 (100)	62 (98.4)	1.0
Curative resection, n (%)	9 (100)	55 (87.3)	0.54
Perforation, n (%)	0 (0)	5 (8.0)	1.0
Delayed bleeding, n (%)	0 (0)	1 (1.6)	1.0

P values were calculated using Fisher’s exact test for categorical data and Mann-Whitney U test for continuous data. GF-ER: Grasping forceps assisted endoscopic resection; ESD: Endoscopic submucosal dissection; IQR: Interquartile range.
