Ultrasound Guided Fine Needle Aspiration Cytology of Gallbladder Lesions Suspected to be Carcinoma Gallbladder: Experience of a Tertiary Care Hospital

ABSTRACT

Gallbladder carcinoma is the most common biliary tract malignancy in the world. Radiologicalinvestigations are helpful in diagnosing the gallbladder diseases especially carcinoma in most of thecases, but confirmation of diagnosis requires cytopathological correlation. We have undertaken astudy on 29 patients, who underwent ultrasound guided FNAC for evaluation of gallbladder lesionssuspected to be carcinoma gallbladder. 82.75% of patients had malignancy or suspicion of malignancyand 10.34% patients had abscesses, while in 6.9 % patients FNAC was inconclusive. Adenocarcinoma(NOS) was the most common diagnosis and was found in 62.6 % of patients. Poorly differentiatedcarcinoma, cytology suspicious of malignancy and abscesses were present in 7 % of patients each.Papillary carcinoma and squamous cell carcinoma were only seen in 3.44 % patients each. None ofthe patients in our study developed any minor or major complications during the procedure. A precisecytological examination is required not only to diagnose or rule out gallbladder malignancy, but alsofor prognostication of these carcinomas.
