摘　　要：目的评价CT引导下经皮二次穿刺活检用于明确诊断肺部病变的可行性及安全性。方法回顾性分析40例接受2次肺穿刺活检患者的临床、影像学及随访资料,根据最终诊断结果,比较2次活检的诊断准确率,分析并发症及初次活检误诊的危险因素。结果40例中,17例初次活检诊断结果与最终诊断一致(确诊组)、23例诊断不一致(误诊组),诊断准确率为42.50%(17/40),并发症发生率为27.50%(11/40);39例二次活检诊断结果与最终诊断一致,诊断准确率为97.50%(39/40),并发症发生率为25.00%(10/40)。二次活检诊断准确率明显提高,并发症发生率与初次活检差异无统计学意义(P>0.05)。组间病灶性质和气胸发生率差异均有统计学意义(P均<0.05)。结论CT引导下经皮二次穿刺活检用于明确诊断肺部病变安全、可行。Objective To explore the feasibility and safety of CT-guided percutaneous secondary biopsy of lung lesions.Methods Clinical,imaging and following-up data of 40 patients who underwent twice lung biopsies were retrospectively analyzed.The diagnostic accuracies of 2 times biopsies were compared according to the final diagnostic results,and complications rates and risk factors for misdiagnosis of the initial biopsy were explored.Results The diagnostic results of the initial biopsy were consistent with the final diagnosis in 17 cases(correct diagnosis group)and inconsistent in 23 cases(incorrect diagnosis group),with the diagnostic accuracy rate of 42.50%(17/40)and complication rate of 27.50%(11/40).The diagnostic results of the secondary biopsy were consistent with final diagnosis in 39 cases,with diagnostic accuracy of 97.50%(39/40)and complication rate of 25.00%(10/40).The diagnostic accuracy of the secondary biopsy was significantly improved,while the complication rate was not significantly different with that of the initial biopsy(P>0.05).There were significant differences of the nature of lesions and the incidence of pneumothorax between groups(both P<0.05).Conclusion CT-guided percutaneous secondary biopsy of lung lesions was safe and feasible.
