“T”型针线在肺部磨玻璃影结节术前定位中的应用

The application of CT-guided localization with a “T” type stitch in treatment of ground-glass opacity with video-assisted thoracoscopic surgery

目的:探讨“T”型针线与hook-wire在术前肺小结节定位中的应用。方法:选取我院64例肺部磨玻璃影患者,随机分为两组进行术前定位,实验组采用“T”型针线定位(32例),对照组采用hook-wire定位(32例),两组患者定位后行电视辅助胸腔镜(VATS)下肺楔形切除术,根据术中冰冻结果采取楔形切除、肺段或肺叶切除术等。记录和分析定位时间、定位准确率,统计并发症发生率、病理结果及住院时间等数据。结果:实验组和对照组资料进行对比,定位成功率分别为100.00%和87.50%,两组患者均无明显并发症并且住院时间无统计学差异。结论:“T”型针线可降低手术风险,是值得继续研究和推广的定位方法。

Objective:To discuss the application of "T" type stitch and hook-wire in pre-opertion CT-guided localization in small pulmonary nodules.Methods: All patients with ground-glass opacity were randomly divided into the experimental group(n=32) and the control group(n=32).The experimental group was given "T" type stitch location,and the control group was given hook-wire location.Then they underwent video-assisted thoracic surgery(VATS) wedge resection.Further operations including segmentectomy or lobectomy were executed according to the intraoperative frozen section.Time of localization,accuracy rate,complications,pathology and hospital stay were analysed.Results: The experimental group(100.00%) had more localization success rate than the control group(87.50%),and there was no obvious complications occurred in both groups.Conclusion: "T" type stitch is able to reduce the operative risk,which is worthy of further res earch and introduce.
