Abstract :
Introduction: FNAC after getting popularity in Scandinavia in early 1970, spread to the world. It is a safe and effective technique for diagnosis of intra-abdominal mass before definitive treatment. When added with image guided techniques (CT/USG), its efficacy increases manifold.Material and Methods: This prospective study was conducted in medical college and hospital over one and half years, fifty subjects with clinically or sonologically detected intra-abdominal lumps were included in the study. Ultrasound guided FNAC was performed on each of them and finally results were compared with Histopathological results of the specimen.Results: Total 50 patients with abdominal mass/lump were included in the study. 32% patients were in 51 – 60 years age and 60% were female patients. Right hypochondrium (44%) was the most common site of lump followed by epigastric region. Satisfactory smears could be made in 43(86%) cases after FNAC. 64% lump turned out to be malignant and 36% were benign. The complications of FNAC were pain and discomfort (14%), post aspiration bleeding (4%), and transient hypotension noted in 2% of cases. The sensitivity and specificity for malignant lesion was 90.32% and 100% respectively. For benign lesion sensitivity was 83.33% and specificity was 100%. Accuracy of cytological diagnosis by FNAC was 86% when compared to histopathological diagnosis.Conclusion: FNAC when guided by imaging modality is a useful investigation for diagnosis. Its specificity is 100% for benign as well as malignant lesion. Its Sensitivity for malignant lesion is 90.32%, whereas for benign lesion was 83.3%.FNAC is found to be safe and simple.
