Abstract
Background: Liver is the second largest organ next to skin and located in right hypochondrium, epigastrium and may extend to left hypochondrium in upper abdominal cavity. It accounts 2% to 3% of total body weight of individual. Land marking for interpreting different diagnostic image and localizing lesions in the liver is commonly done by major fssures. Sound knowledge about different morphological variations which are found on the surface of liver is mandatory to have safe surgical outcome. Segments of liver were extensively researched but there are only few studies dealt with the surface variation of the liver. Therefore, this study aims to assess morphological variations and its specifc location on the surface of adult human liver in Ethiopian cadaver. Methodology: Institutional based cross sectional descriptive study design was conducted in 33 formalin fxed Ethiopian cadaveric livers in the Anatomy department of University of Gondar, Bahir Dar University, Addis Ababa University, St. Paulos Medical School and Hawassa University. Results: 45.45% of the liver was normal but 54.55% showed one or more variations. Additional fssures and very small left lobe with deep costal impressions were seen 27.27% and 21.21% cases respectively. Pons hepatis connecting left lobe with quadrate lobe and very deep renal impression with corset constriction were noted in 9.09% cases each. Additional lobes and absence of quadrate lobes were found in 6.06% cases each. Conclusion and Recommendation: Morphological variations on the liver surface were accessory fssure, very small left lobe with deep costal impressions, pons hepatis, shape variation and absence of quadrate lobe. The most common one among the variations was accessory fssure on the visceral and diaphragmatic surface.
