RESUMO
Objective To explore the risk factors related to postoperative recurrence of uterine fibroid following myomectomy.Methods Four hundred and seventy-three uterine fibroid patients underwent myomectomy were recruited in the case-control study.Leiomyoma characteristics,surgical approach,pathological type and follow-up information were collected by questionnaire.Data were analyzed by correlation analysis and multivariate conditional logistic regression analysis.The calculation of the risk factors associated with the degree of the recurrence after myomectomy was OR and its 95％ confidence interval (95％ CI).Results Among patients,194 cases with recurrence were detected after the 2-7 years follow-up.The number of fibroid removed was the risk factor of postoperative recurrence (OR =2.31,95％ CI:1.57-3.40,P =0.000).Compared with the single fibroid,the risk of recurrence increased 2.31 times in those patients who removed more than two fibroids.Preoperative parity was the protective factor for recurrence (OR =0.63,95％ CI:0.48-0.84,P =0.002).Neither age nor surgical approach or pathological type was associated with the risk of postoperative recurrence related to uterine fibroid following myomectomy.Conlcusion Fibroid number was the risk factor of postoperative recurrence while the preoperative parity was the protective factor.Laparoscopic myomectomy,cellular leiomyoma and muscle intramural leiomyoma did not increase the risk of recurrence.
