  1. LOS, length of hospital stay
  2. Group A: ligation; Group B: clamping; Group C: ligation combined with suturing; Group D: ligation combined with clamping groups; Group E: device group. One-way analysis of variance test for continuous variables (with the statistic F). Multiple comparisons of data was performed Bonferroni test: aGroup A versus Group E; bGroup B versus Group E; cGroup C versus Group E; dGroup D versus Group E. P < 0.001. There was no significant difference between Group A, B, C, D, with all P > 0.05
