Investigate the clinical application value of uterine artery occlusion in long-term effects of laparoscopic adenomyectomy.

A prospective cohort study of patients undergoing laparoscopic adenomyectomy combided with artery occlusion(study group, n=68) was carried out in Beijing Obstetrics and Gynecology Hospital from Jan. 2010 to Jan.2015. 34 patients undergoing simple laparoscopic adenomyectomy in the same period was selected as the control group. For the comparision of the two groups, the operation duration, blood loss during operation, postoperative maximum temperature, the length of postoperative hospitalization, postoperative hemoglobin change, postoperative dysmenorrhea score, menstrual score and recurrence rate were observed.

Compared with control group, the patients of study group show significant less blood loss during operation [(120.30±121.20)ml vs(176.00±149.25)ml] (P<0.05). There was no significant difference in the operation duration, blood loss during operation, postoperative maximum temperature, postoperative hemoglobin change between the two groups (P> 0.05). There was no significant difference in recurrence rate (20.6% vs 23.5%), menstrual score[(1.24±0.45) vs(1.38±0.30)] and dysmenorrhea score[(2.69±1.04) vs(2.78±1.27)] between two groups three years after operation.

Uterine artery occlusion are effective on reducing blood loss during operation, but it may be unuseful in improving long-term clinical outcomes of laparoscopic adenomyectomy.
