目的探讨微波固化在肝脏手术中的止血效果。方法100例肝癌切除手术患者随机分为两组,微波止血组63例,应用针型微波发射极对肝脏做植入式微波固化,结合分步阻断肝血流法切肝。对照组37例,用传统的肝血流阻断法切肝。结果微波固化后的肝脏在切割时几乎处于无渗血状态。不规则性肝切除术中,微波止血组39例,术中出血(13692±4227)ml;对照组22例,术中出血(27636±6807)ml,两组间差异有显著意义(P<001)。规则性肝段肝叶切除术中,微波止血24例,术中出血(30354±8055)ml;对照组15例,术中出血(49067±11310)ml,两组间差异有显著意义(P<001)。结论微波固化在肝癌切除术中止血效果显著,结合分步阻断肝血流法切肝,可缩短肝缺血时间,减轻术后肝功能损害,提高肝癌切除率。
Objective To investigate the hemostatic effect of microwave curing in liver surgery. Methods 100 cases of liver cancer resection were randomly divided into two groups, microwave hemostasis group of 63 cases, the application of pin microwave emitters on the liver to do implantable microwave curing, combined with the step-by-step blocking of hepatic blood flow method to cut the liver. Control group, 37 cases, with the traditional method of hepatic blood flow blocking liver. The results of microwave-cured liver almost no bleeding in the cutting state. In the irregular hepatectomy group, there were 39 cases in the microwave hemostasis group and 13692 ± 4227 ml in the operation group, 22 cases in the control group and 27636 ± 6807 ml in the operation group (P <0.001) ). Hepatectomy in the regular liver segment, microwave hemostasis in 24 cases, intraoperative bleeding (30354 ± 8055) ml; control group of 15 patients, intraoperative bleeding (49067 ± 11310) ml, the difference between the two groups was significant (P < 001). Conclusion Microwave curing has a significant effect on hemostasis during the resection of liver cancer. Combined with the stepwise blocking of hepatic blood flow, the time of hepatic ischemia can be shortened, the postoperative liver damage can be alleviated, and the resection rate of liver cancer can be increased.
