Abstract
Background:
Image-guided fine-needle aspiration cytology (FNAC) serves as first-line diagnostic modalities for the assessment of mural thickening of the gallbladder (GB).
Aim:
The main objective of the present study was to correlate the diagnostic accuracy of preoperative image-guided FNAC of the thickened GB wall based on imaging findings to arrive at a final diagnosis in a tertiary care center.
Materials and Methods:
Fifty-seven image-guided fine-needle aspirations (FNAs) were performed from mural thickening of the GB over a period of 4 years and the smears prepared were stained with Leishman and Papanicolaou (Pap) stain. Out of 57 cases, 51 were included in the study for which follow-up histopathology was performed.
Result:
Out of 51 aspirations, 43 (84.3%) were adequate, 5 (9.8%) were inconclusive, and 3 (5.9%) were inadequate. Among the adequate aspirations, the most common was adenocarcinoma—36 (70.5%). The correlation between confirmatory cytological diagnosis and adequacy was significantly high (P = 0.0001). The overall diagnostic accuracy for adequate aspiration was 95.3%. The common diagnostic pitfalls were necrotic areas, aspiration of reactive hepatocytes adjacent to the GB mass, and mucus islands. No procedural complication was observed in any patient.
Conclusions:
Image-guided FNAC can be used as a safe, rapid, and successful diagnostic procedure with high sensitivity, specifically for supporting and confirming ultrasonography(USG)/computed tomography (CT) diagnosis of GB mass or mural thickening of the wall.
