| Single port | 15 (75) | 9 (45) | |
| Procedure (N (%)) | |||
| Lobotomy | 3 (15) | 8 (40) | >0.05 |
| Segmentectomy | 9 (45) | 3 (15) | |

| Volume of drainage fluid∗∗, mean ± SD, ml | 137.50 ± 64.68 | 119.75 ± 88.62 | >0.05 |
| Chest tube insertion, mean ± SD, d | 3.35 ± 1.09 | 3.40 ± 1.64 | >0.05 |

Values in this term are presented as mean ± standard deviations, median (interquartile range), or numbers (percentage). Length of incision∗: the central operation hole for multiple port VATS in both two groups. Volume of drainage fluid∗∗: the fluid in the first 24 h in each group has been collected.
