CT引导下经皮穿刺活检对肺部疾病的诊断价值研究

The value of CT guided percutaneous biopsy in the diagnose of lung disease

目的研究CT引导下经皮穿刺活检对肺部疾病的诊断价值。方法选取2011年7月至2016年7月我院收治的经CT或胸片证实为肺部疾病患者80例,随机将其平均分为对照组和观察组,每组40例。对照组采用超声仪来进行穿刺活检,观察组利用CT扫描机来进行定位引导,并基于此选定穿刺体位与穿刺点,比较两组的诊断结果。结果观察组利用CT引导进行穿刺,一次性穿刺成功率为100.00%;而对照组采用超声进行引导,一次性穿刺成功率为82.50%。观察组的综合确诊率为92.50%,高于对照组的80.00%,差异具有统计学意义(P>0.05);观察组利用CT引导进行穿刺,整体的并发症发生率为7.50%;对照组采用超声进行引导穿刺,整体的并发症发生率为12.50%,两组比较,差异具有统计学意义(P<0.05)。结论在CT引导下经皮穿刺活检,具有确诊的准确性高、对患者造成的创伤小及并发症发生率低等优点,在临床上具有较高的应用价值。

Objective To explore the value of CT guided percutaneous biopsy in the diagnose of lung disease. Methods Eighty cases of patients with pulmonary disease confirmed by CT or chest X-ray in our hospital from July 2011 to July 2016 were selected and randomly divided into control group and observation group, with 40 cases in each group. The control group used ultrasound for biopsy, while the observation group chose puncture position and puncture point based on CT scanner for positioning and guiding. The diagnostic results of the two groups were compared. Results With CT guided puncture, the success rate of one-time puncture of the observation group was 100.00%. With guided by ultrasound, the success rate of one-time puncture of the control group was 82.50%. The diagnosis rate of the observation group was 92.50%, which was higher than 80.00% of the control group, and the difference between the two groups was statistically significant （P〈0.05）. The observation group was treated with CT guided puncture, and the overall complication rate was 7.50%. The control group was treated with ultrasound guided puncture, and the overall complication rate was 12.50%. The difference between the two groups was statistically significant （P〈0.05）. Conclusion CT guided percutaneous biopsy possess the advantage of high diagnostic accuracy, small trauma, low incidence of complications, which has high application value in clinic.
