Diagnostic role of fine needle aspiration cytology (FNAC) in the evaluation of gall bladder lesions: an institutional experience

Carcinoma of the gall bladder is the most common malignancy of the biliary tract. Ultrasonography guided Fine Needle Aspiration Cytology (FNAC) plays a crucial role in early detection of gall bladder (GB) lesions. Early diagnosis of GB lesions is a necessity in view of rising trend in GB carcinoma related mortality in India. The aim of this study is to determine the diagnostic accuracy of pre‐operative ultrasonography guided FNAC in the diagnosis of GB masses.
