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＞005),C组与A、B组比较差异有显著意义(Ｐ＜005);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＜005）。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 littlepower radioknife (group B) and there were 57 patients operation with highpower 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＜005) . Conclusion： Radioknife for skin flap decoherence in operation of breast cancer can decrease hemorrhage but highpower radioknife will increase necrosis of skin flap.
Obstractive To observe the clinical effects and safety of endobronchial electrocautery treatment for tracheobronchial obstructive lesions in inoperable tracheobronchial squamous cell carcinoma.Methods Ninety-five patients with advanced and inoperable tracheobronchial squamous cell carcinoma were included. Thirty-four patients with central airway obstruction were treated with endobronchial electrocautery plus chemotherapy ( group A) and 61 patients without central airway obstruction were treated with chemotherapy alone ( group B) . The chemotherapy consisted of cisplatin or carboplatin, plus another thirdgeneration chemotherapy agent. Results In groug A, there were mean improvements in FEV1 of 41. 1% and in peak expiratory flow( PEF) of 65. 6% . There was no significant difference in the survival rates of the patients with and without central airway obstruction. Median survival time of group A was 11. 3 months and those of group B was 11. 6 months. 3, 6, and 12-month survival rates in group A were 87% , 68% and 39% respectively, and those in group B were 93% , 76% , and 45% respectively. Conclusion Endobronchial electrocautery is an effective and safe approach for inoperable tracheobronchial obstructive malignancies with few complications.
ObjectiveTo compare the advantages and drawbacks of harmonic scalpel (HS) versus conventional electro-scalpel (ES) in the surgery for carcinoma of uterine cervix. MethodsA total of 126 patients with stage Ⅰ uterine cervix carcinoma who underwent surgery between January 2011 and November 2015 were randomly and averagely divided into HS group and ES group with 63 patients in each. The operation time, intra-operative bleeding volume, the number of lymph nodes detected and operation cost were compared between the two groups of patients. ResultsAll the patients underwent surgery successfully. There were significant differences between the HS and ES groups in terms of operation time[(202.06±11.67) minutes vs.(223.48±18.01) minutes, P<0.001], intra-operative bleeding[(373.97±27.95) mL vs.(458.16±33.18) mL, P<0.001], operation cost[(4 171.43±276.46) yuan vs.(3 101.54±258.59) yuan, P<0.001]. There was no significant difference between the two groups in terms of the number of lymph nodes detected (10.38±2.43 vs.9.76±2.61, P=0.172). ConclusionThe use of harmonic scalpel can reduce operation time and intra-operative bleeding volume effectively, but it cannot increase the number of lymph nodes detected. Moreover, it significantly increases the operation cost and economic burden for the patients.
