EVALUATION OF GALL BLADDER CARCINOMA BY ULTRASONOGRAPHY AND COMPUTED TOMOGRAPHY & ITS COMPARISON: A STUDY OF 50 CASES

OBJECTIVE: Gall bladder carcinoma is the fifth most common tumor of gastrointestinal tract. 70 to 80% of gall bladder carcinomas are associated with gall stones. Adenocarcinoma is the most common histological type of gall bladder carcinoma. Ultrasonography and Computed tomography have revolutionized the diagnosis and management of gall bladder carcinoma. METHODS: The cases were selected based on all patients referred to the Department of Radiology, Gauhati Medical College with clinically suspected Gallbladder carcinoma. Ultrasonography and Computed Tomography were done. Histopathological study was done either by fine needle aspiration cytology or from post-operative specimen. Only the FNAC/histologically proven gall bladder carcinoma cases were included in our study. The age group of the patients ranged from 20 yearrs to 90 yrs. RESULTS: 50 cases of gall bladder carcinoma were studied and among 50 cases, 41 were female and 9 were male. Other parameters like type of tumours, pattern of tumours, adjacent organ involvement etc. was evaluated and tabulated. CONCLUSION: Various findings like female predominance with female to male ratio 3:1, 4th-6th decade was the age group with maximum number of cases etc. can be obtained from the present study. Computed Tomography is more sensitive than ultrasonography in detecting adjacent organ involvement, lymph node involvement and distant metastasis especially lung.
