Variations of the gallbladder in sudanese subjects with literature review

Background: Advances in the use of laparoscopic surgery, especially in the biliary apparatus interference makes the need to revise the anatomical data of the gallbladder (GB) more important. Variations of the extra-hepatic biliary apparatus are characterized by large varieties of configurations. Objective: The aim of this article was to study the morphology of the GB in Sudanese subjects and review the common variations. Materials and Methods: Dissection of formalin-fixed cadavers' abdomens. Results: GB is larger in Sudanese subjects than what is described in the standard text books. Conclusion: Congenital anomalies and anatomical variations of the extra-hepatic biliary tree, although not uncommon, can be of clinical importance. There are some differences in the only size of GB in Sudanese.
