目的: 探讨CT引导下分体活检针穿刺活检技术在肺内占位性病变中的应用价值。方法: 选取2018年1月至2019年6月汕头大学医学院附属肿瘤医院收治肺内占位性病变患者590例为研究对象。记录患者穿刺结果及常规病理检查结果;记录患者术中、术后并发症情况,并分析可能影响并发症发生的因素。结果: 常规病理结果与活检针穿刺结果相符共545例,符合率94.78%。术后70例患者出现气胸,其中62例为单发,8例伴咯血。活检术后气胸的发生与患者年龄、病灶直径、病灶离胸壁的距离及穿刺次数有关(P＜0.05)。活检术后咯血发生与患者病灶直径、病灶离胸壁的距离及穿刺次数有关(P＜0.05)。结论: CT引导下分体活检针穿刺活检技术应用于肺内占位性病变,可提升诊断准确率,值得临床适当推广应用。

Objective: To explore the application value of CT-guided split needle biopsy technique in lung space occupying lesions. Methods: A total of 590 patients with intrapulmonary space-occupying lesions admitted to the Affiliated Tumor Hospital of Shantou University Medical College from January 2018 to June 2019 were enrolled as the study subjects.The results of puncture and routine pathological examination were recorded. The intraoperative and postoperative complications were recorded, and the factors that may affect the occurrence of complications were analyzed. Results: The results of routine pathology were consistent with the results of biopsy needle puncture in 545 cases, with a coincidence rate of 94.78%. Pneumothorax occurred in 70 patients after operation, of which 62 were single and 8 were accompanied by hemoptysis. The occurrence of pneumothorax after biopsy was related to the patient's age, lesion diameter, distance from the chest wall and the number of punctures(P＜0.05). The occurrence of hemoptysis after biopsy was related to the diameter of the lesion, the distance from the lesion to the chest wall and the number of punctures, and the difference was statistically significant(P＜0.05). Conclusion: Ct-guided split biopsy needle puncture biopsy technique can improve the diagnostic accuracy in lung space-occupying lesions, which is worthy of clinical promotion and application.
