做手术为什么要用电刀高频电刀在乳腺癌手术皮瓣游离中的临床应用

摘要:目的：探讨高频电刀在乳腺癌手术皮瓣游离中的临床应用及其功率大小对术后皮瓣坏死的影响。方法：回顾性分析2003年1月至2008年9月,在我院154例行乳腺癌改良根治术患者的临床资料,其中乳腺刀组（A组）37例,小功率电刀组（B组）60例,大功率电刀组（C组）57例,对比分析各组皮瓣坏死情况。结果：共发生皮瓣坏死35例,其中A组用乳腺刀游离皮瓣6例（6/37）,B组用小功率电刀（18～22W）游离皮瓣9例（9/60）,C组用大功率（≥28W）电刀游离皮瓣20例(20/57),B组与A组比较差异无显著意义(Ｐ＞005),C组与A、B组比较差异有显著意义(Ｐ＜005);而B、C组与A组比较,游离皮瓣时出血量明显减少,差异有显著性意义（Ｐ＜005）。结论：合理应用高频电刀游离皮瓣具有术中出血少,术后恢复快的优势,但若功率过高,则会增加皮瓣坏死率。
Abstract: Objective: To Analyse influence of Skin Flap Necrosis after Operation of Breast Cancer with different power of radioknife. Methods：The clinical data of 154 breast cancer patients received surgery operation trea tment was analysed retrospectively, among them there are 37 patients operation with lancet (group A), there were 60 patients operation with littlepower radioknife (group B) and there were 57 patients operation with highpower radioknife (group C). Results：There were 35 cases (22.73％) suffured from skin flap necrosis among 154 breast cancer cases received surgery operation. There were 6 cases（6/37）in group A, 9 cases（9/60）in group B and 20 cases（20/57）in group C. Group B and group C has littler hemorrhage in operation compare with group C (Ｐ＜005) . Conclusion： Radioknife for skin flap decoherence in operation of breast cancer can decrease hemorrhage but highpower radioknife will increase necrosis of skin flap.
