Abstract

In this prospective study, the role of experience in obtaining sufficient samples made by fine needle aspiration biopsy (FNAB) was investigated. Three groups were formed (group A, B and C). In group A (n: 100), surgical residents initially performed FNAB under control of an experienced general surgeon. Then, the residents who have gained experienced made this procedure by themselves at 200 patients (group B). In group C (n: 100), that thought as a control group, FNAB was performed by unexperienced surgical residents during routine outpatient clinic working of a training hospital. In all of these groups, dimensions and localization's of breast masses were not taken care off. In ratios of insufficient sampling in group A was lower than group B and C (4% versus 13% and 19%, respectively) and identically lower in group B of experienced residents than the group C (13% versus 19%).
