常规钩针法与改良钩针法在肺孤立性小结节微创手术术前定位中的应用

Application of hook wire and spring coil for preoperative localization in minimally invasive treatment of solitary pulmonary nodules

目的比较常规钩针法与改良钩针法在肺孤立性小结节微创手术术前定位中的应用价值。方法选取2017年1月至2019年6月常州市武进人民医院收治的行微创手术治疗的孤立性肺小结节病人134例,采用随机数字表法分为对照组与观察组,每组各67例,术前分别行常规钩针法和改良钩针法定位。比较两组定位成功率、定位操作时间及术后并发症发生率。结果观察组定位成功率为100.00%,显著高于对照组的84.62%(P<0.05);观察组定位操作时间为(16.25±3.61)min,显著少于对照组的(20.33±4.55)min(P<0.05);观察组移位脱落发生率0.00%显著低于对照组的11.94%(8/67)(P<0.05)。结论相较于常规钩针法,改良钩针法可有效提高孤立性肺小结节微创治疗术前定位的定位成功率,减少定位操作时间,并有助于预防相关并发症发生风险。

Objective To compare the clinical value of hook wire and spring coil for preoperative localization in minimally invasive treatment of solitary pulmonary nodules.Methods A total of 134 patients with solitary pulmonary nodules by minimally invasive surgery admitted to Changzhou Wujin People's Hospital from January 2017 to June 2019 were chosen and divided into control group and experiment group by random number table method,with 67 cases in each group.Conventional crochet method and modified crochet method were performed before surgery respectively.The location accuracy,location operation time and postoperative complications inci⁃dence of the two groups were compared.Results The location accuracy of the experiment group was 100%,which was significantly higher than 84.62%in the control group(P<0.05).The location operation time of the experiment group was(16.25±3.61)min,which was significantly shorter than(20.33±4.55)min of the control group(P<0.05).The incidence of transposing drop of the experiment group was 0%,which was significantly lower than 11.94%in the control group(P<0.05).Conclusion Compared with conventional crochet,spring coil for preoperative localization on solitary pulmonary nodules by minimally invasive surgery can efficiently improve the positioning accuracy,reduce the location operation time and help to prevent the related complications risk.
