Abstrakt: Background: The anatomy of the biliary tree is complex with anatomical variations which can be found in ~50% of the patients. Purpose: Existing research on these variations primarily stems from studies in developed countries, with uncertain applicability to the Ugandan population due to noted ethnic differences in incidence rates. Objective: The study was aimed at describing the anatomical variations of the gallbladder and bile ducts. Methods: This retrospective cross-sectional study conducted at Kampala MRI Centre from January 2017 to December 2022 analyzed MRCP images and reports from 231 patients to document gallbladder and bile duct variations. Results: 53.2% of patients exhibited typical cystic duct anatomy, and 51% had Type 1 variations in intrahepatic ducts. Importantly, the study identified a significant correlation between age and common bile duct diameter. Conclusion: The findings showed various anatomical variations that were slightly higher in the study population than those reported in the literature. This study emphasizes the critical need for comprehensive knowledge to enhance surgical safety, minimize iatrogenic trauma, and improve the accuracy of diagnostic imaging and hepatobiliary procedures.
