Factors affecting completion of laparoscopic myomectomy.

PURPOSES: This study aimed to elucidate the factors affecting completion of laparoscopic myomectomy without unintended surgery. MATERIALS AND METHODS: The medical records of 143 patients who underwent laparoscopic myomectomy desiring to retain their uterus were retrospectively reviewed. Unintended surgery was defined as the need for conversion to other surgical methods including laparotomy or laparoscopic hysterectomy at any time during the procedures. All variables associated with completion of laparoscopic myomectomy in the univariate analysis were selected at the threshold ofp < 0.25 and then tested in a multiple-logistic regression model. RESULTS: The rate of unintended surgery was 13.3%. Univariate analysis revealed that age, previous abdomino-pelvic surgery, current medical disease, transfusion, > five myomas, myoma size > 8.2 cm, posterior wall location of myoma, intramural type of myoma, and the presence of adenomyosis were statistically significant risk factors for unintended surgery. Multivariate logistic regression analysis demonstrated that completion of laparoscopic myomectomy was significantly influenced by a history of previous abdomino-pelvic surgery (odds ratio; 6.46, 95% CI, 0.03-0.41; p value 0.04). CONCLUSION: The risk of unintended surgery during laparoscopic myomectomy is associated with a history of previous abdomino-pelvic surgery.
