超声与CT引导下经皮肺穿刺活检诊断周围型肺癌的临床应用及对咯血发生率的影响

Clinical application of ultrasound and CT guided percutaneous lung needle biopsy in the diagnosis of peripheral lung cancer and its effect on the incidence rate of hemoptysis

目的探讨超声与CT引导下经皮肺穿刺活检诊断周围型肺癌的临床应用及对咯血发生率的影响。方法选取168例疑似周围型肺癌患者作为研究对象,使用抽签法,随机分为对照组与实验组,分别为51例与117例,给予对照组患者超声引导,给予实验组患者CT引导。对其临床资料进行回顾分析,对比两组患者确诊率与咯血发生率,使用统计学进行分析。结果实验组诊断胰癌71例、鳞癌27例、小细胞癌6例、差分化癌1例;对照组诊断胰癌33例、鳞癌5例、小细胞癌6例、差分化癌0例,对照组患者与实验组患者周围型肺癌确诊率比较差异无统计学意义(P>0.05)。对照组患者的咯血发生率7.84%与气胸发生率3.92%,与实验组患者比较差异无统计学意义(P>0.05)。针对两组的诊断情况进行调查发现,实验组患者的满意率为95.73%,高于对照组(90.20%),组间比较无统计学意义(P>0.05)。结论选超声与CT引导对周围型肺癌患者经皮肺穿刺活检均具有较高的准确率,咯血的发病率较低,均值得临床上推广及使用。

Objective To investigate the clinical application of ultrasound and CT-guided percutaneous lung needle biopsy in the diagnosis of peripheral lung cancer and its effects on the incidence rate of hemoptysis.Methods168patients with suspected peripheral lung cancer were selected as study subjects.The method of drawing lots was used,and the patients were randomly divided into the control group and the experimental group,with51cases and117cases in each group respectively.The control group was given ultrasound guidance,and the experimental group was given CT guidance.The clinical data were retrospectively analyzed.The diagnosis rate and the incidence rate of hemoptysis were compared between the two groups,and statistical analysis was carried out.Results In the experimental group,there were71cases of pancreatic cancer,27cases of squamous cell carcinoma,6cases of small cell carcinoma,and1case of differentiated carcinoma.In the control group,there were33cases of pancreatic cancer,5cases of squamous cell carcinoma,6cases of small cell carcinoma,and0case of differentiated carcinoma.There was no statistically significant difference in the diagnosis rate of peripheral lung cancer between the control group and the experimental group(P>0.05).In the control group,the incidence rate of hemoptysis was7.84%and the incidence rate of pneumothorax was3.92%.There was no statistically significant difference compared with those in the experimental group(P>0.05).According to the investigation of the diagnosis of the two groups,the satisfaction rate in the experimental group was95.73%,which was higher than that in the control group(90.20%).There was no statistically significant difference between the two groups(P>0.05).Conclusion Ultrasound and CT guidance for percutaneous lung needle biopsy have a higher accuracy in the diagnosis of patients with peripheral lung cancer.The incidence rate of hemoptysis is low,and it is worthy of clinical promotion and application.
