Table 2. Comparison of surgical outcomes between the two groups.
| Surgical outcomes | Group A (n=21) | Group B (n=17) | P value | OR (95% CI) |
|---|---|---|---|---|
| Operation time (min) | 207±21 | 209±15 | 0.75 | |
| Time for the laparoscopic procedure (min) | 44±5 | 47±6 | 0.09 | |
| Number of successful esophageal mobilizations to the level of the diaphragm | 9 (42.9) | 15 (88.2) | 0.004 | 10 (1.809–55.284) |
| Blood loss (mL) | 15±6 | 14±5 | 0.73 | |
| Number of resected lymph nodes | 19±4 | 20±2 | 0.20 | |
| Lymph node ratio (%) | 4±11 | 4±11 | 0.87 |
Continuous data are presented as the mean ± standard deviation. Categorical data were expressed as counts and percentages. Group A: traditional mediastinoscopy combined with multi-port laparoscopy; Group B, modified secondary mediastinoscopy combined with “SI + 1” laparoscopy. OR, odds ratio; CI, confidence interval; SI + 1, single-incision plus one-port.
