摘　　要：目的:探讨CT引导下新型钩线系统用于孤立性肺小结节胸腔镜(VATS)术前定位的临床应用价值。方法:回顾性分析接受术前CT引导下肺小结节定位的92例患者的临床及影像资料,其中63例患者(63个肺小结节)采用CT引导的带钩钢丝定位(A组),29例患者(29个肺小结节)采用CT引导的新型钩线系统定位(B组)。采用t检验和卡方检验对A、B两组病例的定位手术时间、成功率、并发症发生率进行比较。结果:所有患者均成功完成VATS手术,A组有2例定位器脱落,B组有1例定位器脱落,两组定位成功率比较差异无统计学意义(分别为96.8%和96.6%,P=1.000);B组患者的中重度疼痛发生率明显低于A组,差异有统计学意义(分别为0%和17.5%,P=0.04);两组的平均定位手术时间比较差异无统计学意义(分别为12.5 min和13.2 min,P=0.222),两组其他并发症的发生率差异无统计学意义(P>0.05)。结论:孤立性肺小结节VATS术前应用CT引导新型钩线定位的效果显著,值得临床推广应用。Objective:To explore the clinical application value of the new CT-guided hook-wire system in positioning of solitary pulmonary nodules before video-assisted thoracic surgery(VATS).Methods:The clinical and imaging data of 92 patients who received preoperative CT-guided pulmonary nodule localization were retrospectively analyzed.Among them,63 patients(63 pulmonary nodules)were located by CT-guided hook-wire(group A),and 29 patients(29 pulmonary nodules)were located using the new CT-guided hook-wire system(group B).The t-test and chi-square test were used to compare the positioning operation time,success rate,and complication rate between the two groups.Results:VATS surgery was successfully completed in all patients.There were 2 cases and 1 case of locator falling off in groups A and B,respectively.There was no statistically significant difference in the positioning success rate between the two groups(96.8%vs.96.6%,P=1.000).The rate of moderate to severe pain in group B was significantly lower than that in group A(0%vs.17.5%,P=0.04).There were no statistically significant differences in the average positioning operation time(12.5min vs.13.2min,P=0.222)and in the incidence of other complications(P>0.05)between the two groups.Conclusion:The new CT guided hook-wire positioning system for small solitary pulmonary nodules before VATS has good localization ability and is worthy of clinical application.
