Laparoscopic Myomectomy with Temporary Bilateral Uterine Artery and Utero-Ovarian Vessels Occlusion Compared with Traditional Surgery for Uterine Fibroids: Blood Loss and Recurrence.

AIM: To determine the optimal hemostatic technique for laparoscopic myomectomy (LM) by comparing temporary uterine artery blockage alone or combined with blockage of the utero-ovarian vessels.

PATIENTS: Women with symptomatic uterine myoma attending the Department of Obstetrics and Gynecology in Jinhua Municipal Central Hospital.

METHOD: A total of 200 patients with symptomatic uterine fibroids were randomly divided into Group A (n = 65), Group B (n = 67) and Group C (n = 68). At the beginning of the procedure, 6 U of vasopressin was injected into the myometrium of all women. LM was performed in Group A; temporary bilateral uterine artery occlusion and myomectomy were performed in Group B and temporary bilateral uterine artery and utero-ovarian vessel occlusion was performed in Group C. We then evaluated operative time, perioperative bleeding, follow-up relief of menorrhagia, and the recurrence of fibroids.

RESULTS: General characteristics of the patients were similar across all 3 groups. All patients underwent successful laparoscopic operation and none of the cases needed to be converted to laparotomy; there were no intraoperative complications. There was no significant difference in the operative time between groups (p = 0.332 and p = 0.346 for single-myoma and multiple-myoma respectively), and for both single and multiple-myoma groups, the blood loss was significantly lower in Group C than Groups A and B (p < 0.001). There were no differences in the recurrence rate and menorrhagia symptom relief outcomes when -compared across the 3 groups at the 30-month follow-up (p = 0.953 and p = 0.841, respectively). At final follow-up, the pregnancy rate of the sexually active patients without contraception was not statistically significant (p = 0.958). The fertility index of anti-Mullerian hormone showed no statistical difference between groups preoperatively or at 2 days, 3 months, 6 months, and 1 year postoperatively (p = 0.998, p = 0.965, p = 0.999, p = 0.994 and p = 0.993, respectively).

CONCLUSION: LM with temporary bilateral uterine artery and utero-ovarian vessels occlusion has the advantages of less intraoperative bleeding compared with LM and laparoscopic transient uterine artery ligation and does not increase the mean operative time.
