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 groups:1 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.
