MR imaging and clinical features associated with intraoperative hemorrhage during laparoscopic myomectomy

This study included 126 patients clinically and pathologically diagnosed as uterine leiomyoma between 2010 and 2015. These findings were statistically compared between significant intraoperative hemorrhage group (greater than 300 ml) and nonsignificant intraoperative hemorrhage group (less than 300 ml). Correlation between the maximum diameter of resected leiomyomas and the maximum diameter leiomyomas on MR imaging were also evaluated. Significant hemorrhage group showed larger maximum diameter of resected leiomyoma (p = 0.01), larger maximum diameter of leiomyoma on MR imaging (p = 0.01) and have cellular leiomyomas on MR imaging more frequently (p = 0.03) than nonsignificant intraoperative hemorrhage group. The maximum diameter of resected leiomyomas significantly correlated with that of leiomyomas on MR imaging (Spearman’s rho = 0.797, p < 0.001). The cutoff value of maximum diameter of uterine leiomyoma on MR imaging between both groups was 7.27 cm. The MR imaging findings of a large uterine leiomyoma (more than about 7.3 cm) may predict significant intraoperative blood loss during laparoscopic myomectomy.
