Magnetic anchor technique assisted endoscopic submucosal dissection for early esophageal cancer

Table 1 Comparison of results of the two groups

	Operational group (n = 10)	Control group (n = 10)	P value
Total operative time (min)	17.04 ± 0.22	21.94 ± 0.23	< 0.001
Perforation rate (%)	90	60	0.302
Rate of whole mucosal resection (%)	90	80	-
Diameters of the peering mucosa (cm)	2.13 ± 0.06	2.15 ± 0.06	0.822
Scores of convenience1	9.22 ± 0.19	8.34 ± 0.15	0.002
Scores of mucosal surface exposure degree1	9.11 ± 0.15	8.25 ± 0.12	< 0.001
Scores of tissue tension1	9.35 ± 0.13	8.02 ± 0.17	< 0.001

¹Endoscopist’s operational feeling scores which were limited from 0 to 10 reflect their feelings about convenience, mucosal surface exposure degree, and tissue tension with the surgical procedure. Higher scores indicate greater satisfaction.
