Diagnostic Accuracy of Contrast-Enhanced Computed Tomography (CECT) and Ultrasonography (USG) in Diagnosing Carcinoma Gallbladder keeping Histopathology the Gold Standard

Objective: To evaluate the comparative role of ultrasonography and contrast-enhanced computed tomographyin diagnosis carcinoma gallbladder. Early experience at a hepatobiliary unit in tertiary care hospitalStudy Design: Cross sectional study.Place Duration Study: The study was carried out Hepatobiliary Unit Pak Emirates MilitaryHospital, Rawalpindi from July 2021 to June 2022.Materials Methods: USG CECT scans were used assess diagnostic accuracy CarcinomaGallbladder. 30 patients, with an average age 54 years, part this study. Patients included thestudy based on radiological findings pertinent gallbladder cancer which include fossa massreplacing gallbladder, focal/intraluminal/polypoidal growth asymmetrical/diffuse thickness ofgallbladder. All resected specimens sent for histological investigation after operation, histopathologyserving as Gold standard.Results: On examination, 13.3% gallbladders contracted reduced size, while70% large distended. has sensitivity specificity 96% 80%, respectively, identifyingGB carcinoma. scan had 92% 60%. There test agreement isexcellent (Kappa value 0.819) between two techniques, indicating that modalities arenearly equivalent terms diagnosing Gallbladder.Conclusion: indicate both are ideal, non-invasive, safe imagingmodalities additional advantage defining theextension disease involvement surrounding structures including lymph nodes hepatoduodenal ligament.
