Objective: To assess the factors influencing operative time and intraoperative blood loss in patients who had undergone laparoscopic myomectomy (LM). Methods: The study involved 374 patients who had undergone LM at our hospital between May 2009 and April 2011. We examined the relationships between operative time, intraoperative blood loss, maximum myoma diameter, number of resected myomas, and myoma growth patterns (5 groups: intramural, submucosal, subserosal, pedunculated subserosal, and intraligamentous). Results: There was a correlation between maximum myoma diameter, operative time (y = 0.73x + 51.51; r = 0.393), and intraoperative blood loss (y = 3.76x - 121.12; r = 0.456). Furthermore, the number of resected myomas was correlated with operative time (y = 5.06x + 81.71; r = 0.308) and intraoperative blood loss (y = 3.49x + 99.55; r = 0.049). There was a significant difference in operative time between pedunculated subserosal myomas and intraligamentous myomas, but there was no significant difference in intraoperative blood loss between myomas displaying different growth patterns. Conclusions: The maximum myoma diameter was a factor influencing operative time and intraoperative blood loss. In addition, the results suggested that operative time was influenced by the number of resected myomas and the growth patterns of myomas.
