Ultrasound guided automatic biopsy in diagnosis of splenic space-occupying lesions

Objective:To evaluate ultrasound guided aspiration biopsy (USGAB) in diagnosis of splenic space-occupying lesion.Methods:Twenty-two patients with or combined with metastatic carcinoma of the spleen were detected by USGAB,and the tissues underwent pathologic examination.Results:Twenty cases were punctured once,and the rest twice.The average needle pass was (2.28±0.46) times,and the average length of the core organization was (14.7±1.3) mm.The puncture success rate was 100%,and the pathological diagnosis rate was 100%.Among the 22 cases,17 were malignant lesions and 5 benign lesions.No serious complications occurred.Conclusions:USGAB technology is safe,accurate and rapid in pathological diagnosis of splenic space-occupying lesion.It is an effective diagnostic method.
