Objective To explore the efficacy and safety of microwave hemostatic device in laparoscopic microwave ablation for exogenic hepatic hemagioma.Methods The clinic data of 62 patients with exogenic hepatic hemagioma who performed with laparoscopic microwave ablation between May 2015 and May 2017 were retrospectively analyzed.According to the different surgical technique,the patients were assigned into microwave hemostatic device combined with microwave ablation group (combination group,29 patients) and microwave ablation group (microwave group,33 patients).The microwave group was performed laparoscopic microwave ablation,and the combination group was pretreated the surface of hemagioma with microwave hemostatic device before laparoscopic microwave ablation.The intraoperative and postoperative conditions of the patients were recorded and analyzed.Results All patients were performed successfully under laparoscope without conversion to laparotomy.The average time of microwave ablation was significantly shorter in combination group than in microwave group [(10.69 ±3.54) min vs.(13.18 ± 4.31) min,P＜0.05].Compared with microwave group,the average bleeding amount of operation was significantly lower in combination group[(48.79±20.30) mL vs.(95.76±90.16) mL,P＜0.05].All patients from both groups recovered uneventfully without any complications such as abdominal bleeding or bile leakage.Conclusion For exogenic hepatic hemagioma,the microwave hemostatic device is used to solidify the surface of hemagioma before microwave ablation,which can improve the safety of the operation,reduce the time of microwave ablation,and avoid tumor hemorrhage caused by puncture.
