TABLE 2.
Outcome measures of the 4318 patients submitted to laparoscopic liver resection at 41 Italian surgical centers between November 2014 and January 2021
| Outcome | Weighted values (95%C.I.) | Heterogeneity (I2)* |
|---|---|---|
| Conversion | 8.1% (6.5–10.) | 73.4% |
| Any complication | 21.8% (18.5–25.5) | 84.9% |
| Major complications | 5.9% (4.9–7.1) | 46.5% |
| Mortality | 0.7% (0.5–1.1) | 0.0% |
| LOS (days) | 6.0 (5.6–6.3) | 88.5% |
| >6 days† | 27.1% (23.2–31.3) | 86.9% |
Values are weighted proportions estimated through random effect model. Continuity correction of 0.5 in studies with zero cell frequencies was adopted.
*I2 statistic can be interpreted as follows: values of <25% = low heterogeneity; 25% ‐ 50% = medium, 51% ‐ 75% = substantial and > 75% = considerable heterogeneity.
†Based on the 75th percentile of the median values of each center.
