摘要
目的探讨同轴半自动活检枪在肺小结节穿刺活检中的应用价值。方法回顾性分析我院因肺部小结节行CT引导穿刺活检的40例患者资料,以术后病理或影像随访结果为金标准,计算穿刺活检诊断恶性肺小结节的敏感度、特异度和准确率,并分析术中手术相关并发症及穿刺技巧。结果所有患者均完成手术操作,术后病理或影像随访最终诊断为恶性病变29例、良性病变11例。穿刺活检诊断恶性肺小结节的敏感度为89.65%(26/29)、特异度为100%(11/11)、准确率为92.50%(37/40)。手术相关并发症主要为气胸和局部出血。结论采用同轴半自动活检枪对肺小结节患者行穿刺活检,具有较高的准确率、特异度及敏感度,是一种安全有效的诊断方法。
Objective To explore the application value of coaxial semi-automatic biopsy gun in the biopsy of small pulmonary nodules. Methods A retrospective analysis was performed on 40 patients with small pulmonary nodules who underwent CT guided percutaneous pulmonary nodules biopsy. Taking postoperative pathology diagnosis or imaging follow-up results as gold standard, the accuracy, specificity, sensitivity, intraoperative complications and puncture techniques of biopsy were analyzed. Results All operations were successfully completed. There were 29 malignant lesions and 11 benign lesions confirmed by postoperative pathology diagnosis or imaging follow-up results. The sensitivity, specificity, accuracy rate of puncture biopsy in diagnosis of malignant small pulmonary nodules was 89.65% （26/29）, 100% （11/11）, 92.50%（37/40）. The main complications were pneumothorax and local hemorrhage. Conclusion Percutaneous biopsy of small pulmonary nodules using coaxial semi-automatic biopsy gun has high accuracy, specificity and sensitivity, is a safe and effective method.
