Clinic research of CT guided localization with a hook-wire system for small ground glass opacity pulmo-nary nodules united with single port video-assisted thoracoscopic resection / 国际肿瘤学杂志

ABSTRACT

Objective To evaluate the clinical effect of CT guided localization with a hook-wire system united with single port video-assisted thoracoscopic resection (VATS)for small ground glass opacity (GGO) pulmonary nodules (CT lesion diameter <1 .5 cm and no pleural changes).Methods Fifteen patients with small GGO pulmonary nodules who underwent CT-guided transthoracic localization with a hook-wire system in operation room after anesthesia were performed with single port VATS from August 2009 to March 201 3.The accuracy of puncture location,complications,resection rate and pathological results were evaluated.Results All patients underwent CT-guided hook-wire localization and single port VATS resection.The success rate of localization was 1 00%,and the average procedure time was (1 3.60 ±2.06)min,only 1 patient occurred mini-mal pneumothorax.The resection rate of single port VATS was 1 00%,and lobectomy performed in 1 patient, segmentectomy in 1 ,and local resection in 1 3.Pathological diagnosisadenocarcinoma in situ in 9,atypical adenomatous hyperplasia (AAH)in 5,AAH and adenocarcinoma in situ in 1 .Post-operation follow-up showed all patients survived,and no recurrence and metastasis.Conclusion In operation,use of CT guided localiza-tion with a hook-wire system for small GGO pulmonary nodules (CT lesion diameter <1 .5 cm and no pleural changes)united with video-assisted thoracoscopic resection is accurate,quick and safe,and it has good clinical value.
