Clinical analysis of computed tomographic-guided lung biopsy with coaxial technique for 63 cases / 中国基层医药

ABSTRACT

Objective To evaluate diagnostic value and analyze the complications of the lung nodules by 64 slice CT guided percutaneous thoracic biopsy(PTB)with coaxial technique.Methods The clinical data of 63 patients with lung placeholder in coaxial line casing biopsy under CT guidance were retrospectively analyzed.After CT positioning,16G coaxial trocar rapidly passed through the pleura,the tip to the edge of the tumor or pathological lesions,pulled out the needle core,the coaxial sleeve in 18G semi automatic biopsy needle,the materials were multi-angle cuted and sent to the pathology examination,the positive rate and the incidence of complications were analyzed.Results In 63 cases of lesions under CT guidance,the success rate of drawing materials was 100.0%,the pathological diagnosis rate was 88.9%.Intraoperative and postoperative complications occurred in 18 cases,the incidence rate was 28.6%,among them 9 cases of pneumothorax(14.3%),pulmonary hemorrhage in 8 cases(12.7%),hemoptysis in 1 case(1.6%),no severe adverse reaction was observed.Conclusion Multi slice CT guided percutaneous coaxial biopsy has the advantages of simple operation,high diagnosis rate,less complications,low risk,it can be promoted in hospitals.
