Abstract

OBJECTIVE
The objective of this study is to evaluate the safety and the clinical efficacy of the laparoscopic myomectomy through analyzing several operation factors.
METHODS
There were 185 cases of laparoscopic myomectomy between January 2004 and December 2008 at the department of obstetrics and gynecology in Hanyang University Guri Hospital. Retrospectively many factors of the operation were analyzed. The factors include the size, number and type of the myoma, BMI (body mass index), operation method, operation time, and complication and the prognosis of the operation.
RESULTS
For the type of myomas, 115 (62.2%) cases were intramural myomas, 38 (20.5%) cases were subserosal types and 32 (17.3%) cases were mixed types. The average diameter of the biggest myoma was 6.67+/-0.16 cm (range, 2.5~15 cm) and the average number of the myoma was 2.07+/-0.15 (range, 1~15). Previous operation history and pelvic adhesion did not show correlation with the operation time. The size, type and number of myoma and the operation methods showed correlation with the operation time. According to myoma size and number, we divided the cases into two groups, low risk group (122 cases) and high risk group (63 cases). The analysis showed that post-operation hemoglobin drop (2.89+/-0.10 g/dL vs. 4.03+/-0.23 g/dL) and blood transfusion amount (2.89+/-0.10 pints vs. 4.03+/-0.23 pints) as well as the operation time (137.58+/-4.37 min vs. 193.73+/-9.88 min) showed noticeable increase in the high risk group.
CONCLUSION
This statistics show that laparoscopic myomectomy is now being applied to patients with larger and more myomas. Factors affecting operation time were the weight of myomas, number of myomas, type of myomas, number of trocars and methods of resected myomas removal. Also, operation time and post-operative hemoglobin drop increased in the high risk group.
