Abstract: Objective: To explore the clinical effect and surgical technique of modified laparoscopic hysteromyomectomy(LM).Methods: Forty-five cases of hysteromyoma were treated using modified LM.The myoma matrix was sutured continuously with deep muscular layer and shallow muscular layer at intervals;the big myoma was resected at first,and then part of the tumor body was removed by potary cutting.Results: The LM was successful in all the 45 cases,and no case was converted to open surgery.Intraoperative blood loss was 20-180 ml,and the operation time was 50-140 min.No complications occurred.Conclusions: Modified LM is safe and effective for treatment of hysteromyoma with minimal invasion.Proper indication and suture technique are essential.
