Dissection time per cm² of each group

	Device not used (min/cm2)	Device used (min/cm2)	Significant (p)
Overall	6.3 ± 3.6	3.18 ± 2.29	<0.01
	n = 37	n = 37
Group A	5.8 ± 4.34	2.1 ± 1.54	<0.01
	n = 12	n = 12
Group B	6.1 ± 3.44	3.8 ± 2.64	<0.05
	n = 19	n = 19
Group C	7.9 ± 2.39	3.6 ± 1.72	<0.01
	n = 6	n = 6

Group A, easy: anterior wall, posterior wall, greater curvature of antrum; Group B, intermediate: front view of antrum, lesion over an angle, lesser curvature of corpus; Group C, difficult: greater curvature of corpus, fornix. Data are mean ± SD unless otherwise indicated
