title: A new syringe for fine needle aspiration biopsy.
abstract: In order to improve the technique of fine needle aspiration biopsy (FNAB), we developed a disposable syringe that allows one to perform aspiration with one hand while eliminating the need for a classic syringe holder. This study compared the cellularity and diagnostic adequacy of the material obtained with the new syringe and a syringe holder. Moreover, the acceptance of the new technique by physicians in training and by patients was tested. FNAB was performed with a syringe holder and the new syringe on 120 lesions from different body sites. The total number of diagnostic cells and their relative percentage were estimated. The results of the study indicated that the adequacy of a conclusive cytologic diagnosis was similar for both techniques. Moreover, a comparable cellular yield was demonstrated by a linear relationship between the total number of diagnostic cells (r = .84, slope = .83). The new technique was favorably accepted by physicians in training and patients. FNAB with the new syringe can be performed routinely.
