目的 探讨微波止血分离器在腹腔镜外生型血管瘤微波消融中应用的疗效和安全性。方法 回顾性分析2015年5月至2017年5月在该院进行微波消融的62例外生型血管瘤患者的临床资料。根据术中治疗方式的不同分为微波止血分离器联合微波消融组（联合组,29例）和单纯微波消融组（微波组,33例）,微波组在腹腔镜下直接行肝血管瘤微波消融,联合组在腹腔镜下先使用微波止血分离器行血管瘤表面固化,再行微波消融。观察患者术中及术后情况。结果 所有患者均在腹腔镜下顺利完成手术,无中转开腹,联合组微波消融时间[（10.69±3.54）min]低于微波组[（13.18±4.31）min,P〈0.05]。联合组[（48.79±20.30）mL]低于微波组[（95.76±90.16）mL,P〈0.05]。两组患者术后均顺利恢复,无腹腔出血、胆漏等并发症。结论 肝外生型血管瘤进行微波穿刺消融前,使用微波止血分离器进行瘤体表面固化,可提高手术安全性,减少消融所需时间,避免穿刺引起的瘤体出血。

英文摘要：

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 lap- aroscopic 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 micro- wave 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.
