Results of TWL determined (Sec).
| Group | Before operation | 1 d after operation | 3 d after operation | 7 d after operation | 14 d after operation |
|---|---|---|---|---|---|
| Group C | 1.83 ± 0.23 | 1.82 ± 0.21 | 1.83 ± 0.20 | 1.82 ± 0.20 | 1.80 ± 0.29 |
| Group PS | 1.81 ± 0.18 | 1.4 ± 0.12a | 1.2 ± 0.13a | 0.8 ± 0.18a | 0.5 ± 0.21a |
| Group PR | 1.82 ± 0.09 | 1.68 ± 0.14b | 1.49 ± 0.10b | 1.25 ± 0.21b | 1.79 ± 0.32b |
Results of TWL determined. Group PS has markedly shorter TWL than group C at 1, 3, 7, and 14 d after operation (p < 0.05), but group PR has obviously longer TWL than group PS (p < 0.05). ap < 0.05 vs. group C; bp < 0.05 vs. group PS.
