Mean age (years, ± SD) 45.44 ± 8.97 44.41 ± 9.05 43.65 ± 7.94 0.639
Body mass index (kg/m2, ± SD) 2.22 ± 0.19 2.16 ± 0.18 2.19 ± 0.21 0.426
Resected tumor tissue (g, ± SD) 56.61 ± 11.57 58.41 ± 8.53 58.77 ± 9.90 0.690
Tumor size (cm, ± SD) 1.94 ± 0.48 1.76 ± 0.34 1.92 ± 0.47 0.103
Time of operation (minutes, ± SD) 149.66 ± 14.92 152.17 ± 15.14 152.30 ± 16.36 0.683

  1. Age and operation time were normal distribution and homogeneity of variance, and one-way ANOVA was used. BMI, resected tissue, tumor size, and length of hospital stay were measured by the Kruskal–Wallis test
