VALIDITY OF COMPUTED TOMOGRAPHY IN DIAGNOSING GALLBLADDER MASSES AND THEIR CORRELATION WITH FINENEEDLE ASPIRATION CYTOLOGY AND HISTOPATHOLOGICAL EXAMINATION IN A TEACHING HOSPITAL IN NORTH-EAST INDIA.

Introduction: Gallbladder carcinoma (CA) is the most common primary biliary carcinoma and fth most common malignancy of the gastrointestinal tract. Incidence of gall bladder carcinoma is highest in Asian countries and this had increased recently due to improved detection rates. Approximately 90% of Gall Bladder cancers have accompanying cholelithiasis. Adenocarcinoma is the most common histologic type, accounting for 98% of all gallbladder tumors with almost a third of cases presenting with distant metastasis. 1.To study various features of CT in GB masses. 2.To detect the sensitivity, spe Objectives: cicity, positive predictive value and negative predictive value of CT in diagnosing gall bladder masses by comparing with ndings ne-needle aspiration cytology (FNAC) and histopathological examination. Materials and Method: Total 50 patients are included in this study who have presented to Surgery OPD, Agartala government medical college and GBP hospital with symptoms related to GB masses. All the patients subsequently undergo MDCT and subsequently CT guided FNAC for cytological correlation and followed up to post operative histopathological examination Results: In our study, age of the GB mass patients was ranged from 30 to 90 years. Maximum number of patients were in the age group between 51 and 60 years, about 29%, and age group between 61 and 70 years, about 27%. Minimum number of patients were in the group between -30-40 years and 81–90 years. The average age of the patients presented was 58 years. Of 50 patients of the GB masses, 65% were detected in females and 35% were detected in males. Female predominance is seen. Conclusion: The overall mean age of the patients presented was 58 year, and the overall female-to-male ratio was 1.9:1. The most common presenting symptom was jaundice which was seen in 87% of cases. In our study, overall detection of GB carcinoma CT could detect 93% of cases same as FNAC detection of GB carcinoma.
