目的 探讨超声引导普通细针 (2 2G)穿刺抽吸活检与弹射式粗针活检对肝癌诊断与疗效判断的价值。方法 对超声引导介入注射无水酒精等药物治疗的 112例肝癌患者的治疗前后行普通细针抽吸细胞学与组织学活检 ,并与同部位粗针活检对比。所取组织能作出明确的细胞学或 (和 )组织学病理诊断者为取材成功。结果 112例于治疗前后共细针活检 3 2 2例次 ,平均每例次穿刺取样进针 2 .1次 ,同一部位粗针活检 3 8例 ,共 113次 ,平均每例次穿刺取样进针 1.8次 ,治疗前细粗针间活检取材成功率比较差异无显著性意义 (P >0 .0 5 ) ,但治疗后细针活检的取材成功率呈明显的递减改变。结论 普通探头引导普通细针抽吸活检具有“一针两用”、方便、安全与费用相对低廉的优点 ,对肝癌的诊断与疗效判断有较高的临床应用价值 ,弹射式粗针活检于治疗前后均有很高的取材成功率 ,对于细针取材不易成功的病例应改用粗针切割活检为宜
Objective To investigate the value of ultrasound-guided normal fine needle (22G) needle biopsy and ejection-type needle biopsy in diagnosis and therapeutic evaluation of liver cancer. Methods A total of 112 patients with hepatocellular carcinoma who underwent ultrasound-guided interventions such as absolute alcohol were treated with normal fine needle aspiration cytology and histological biopsies before and after treatment, and compared with the same site biopsy. The tissue taken can make a clear cytology or (and) histological pathology diagnosis was successful. Results A total of 321 cases of needle biopsy were performed before and after treatment. The average number of needles per procedure was 2.1 times, and the number of needle biopsy in the same site was 38, a total of 113 cases. 1.8 times, there was no significant difference in the success rate between the fine and coarse needle biopsy before treatment (P > 0.05), but the success rate of the fine needle biopsy after treatment was significantly reduced. Conclusion Ordinary probe-guided conventional fine-needle aspiration biopsy has the advantages of “one-needle dual-use”, convenience, safety and relatively low cost. It has high clinical application value for the diagnosis and curative effect evaluation of liver cancer. Ejection-type needle biopsy is used for treatment. There is a high success rate in both reading and writing, and it is advisable to use a thick needle cutting biopsy in cases where it is difficult to obtain successful results with fine needles.
