ABSTRACT
Objective To evaluate the clinical application value of a new type of Bard Max-Core coaxial biopsy system and com-pare the effectiveness and safety of different diameter biopsy guns.Methods This retrospective study included 286 patients who re-ceived CT-guided percutaneous lung biopsy using Bard MC disposable biopsy system.We divided patients into three groups1 6G, 18G,and 20G group.Then,we evaluated the biopsy effectiveness,histological diagnosis rate and complication incidence of this new type of Bard Max-Core coaxial biopsy system.Results All lung biopsy specimens were successfully obtained.The total histological diagnosis rate was 80.8%.Patients with malignant lesions had higher histological diagnosis rate than patients with benign lesions. The histological diagnosis rate in 1 6G group was the highest among three groups.There was no significant difference among three groups regarding to the rate of diagnosis of malignant lesions.Group with 1 6G had the highest histological diagnosis rate among three groups in diagnosing begin lesions.The incidences of pneumothorax in three groups had no significant difference.The incidence of bleeding in 1 6G group was the highest among three groups.Conclusion The new Bard MC disposable coaxial biopsy system is a safe and effective instrument for lung biopsy.We should select the biopsy needles with appropriate diameter according to the fully as-sessment of patients'preoperative conditions.
