Factor | Number | OR (95% CI) | p-Value |
|---|
Large leiomyoma | 44 | 9.5 (1.1–79.0) | 0.072 |
Multiple leiomyoma | 43 | 4.2 (0.8–21.3) | <0.01 |
Heavy leiomyoma | 28 | 3.4 (0.9–13.3) | 0.68 |
Adhesion | 23 | 3.0 (0.8–11.6) | 0.056 |
Higher BMI | 16 | 5.5 (1.4–22.4) | <0.01 |
- Five factors were defined as follows: (1) “large leiomyoma,” defined as a dominant leiomyoma ≥ 8 cm; (2) “multiple leiomyomas,” defined as two or more leiomyomas; (3) “heavy uterus,” defined as total weight of the resected specimens ≥ 400 g; (4) “higher BMI,” defined as BMI ≥ 25 kg/m2; (5) “adhesion,” diagnosed during operation. The relationship between a difficult operation (DO), which was defined as an operation time exceeding 120 minutes or more than 400 ml of blood loss, and these five factors was assessed by multivariate analysis. In this analysis, both “multiple leiomyoma” and “higher BMI” were associated with a significantly higher probability of DO. In addition, “larger leiomyoma” and “adhesion” trended towards increased DO probability. In contrast, “heavy leiomyoma” showed no impact
