Abstract

Introduction: The liver is the largest organ secondary to the skin. It occupies most portion of the upper abdominal space. It accounts approximately 2% to 3% of total body weight for everyone. The liver has four lobes namely right, left, caudate, and quadrate, but based on physiological classification liver has eight segments. The liver is the vital organ without which the tissues of the body die from a lack of energy and nutrients. Major and minor grooves of the liver play a crucial role in hepatectomy as they are significant in the localization of the tumor. So Anatomical evaluation and a better surgical understanding of the liver are essential. Aim: The present study aims to determine the gross anatomical variations of the liver. Materials and Methods: Present morphological study was conducted on 60 formalin-fixed livers which were observed for the study in the Dept. of Anatomy, D.Y. Patil Medical College, Navi Mumbai, Maharashtra, India. Different variations in lobes, fissures, and accessory lobes, decrease in size of lobes, lobar atrophy, and any other variations on the surface of the livers were observed. Results: Out of 60 livers studied; Abnormal fissures were present in-12(20%), absence of quadrate lobe 2(3.3%), Right lobe with projection (tortoise shape) 1(1.6%), saddle like with elongated left lobe of liver 2(3.3%), concavity on anterior surface 1(1.6%), hypertrophied caudate lobe 3(5%), right lobe3(5%), and bilobed quadrate lobe1(1.6%) Conclusion: Knowledge of anatomical and morphological variations of the liver is important for anatomists, radiologists, and surgeons. Awareness of this variation will be helpful during imaging techniques and surgeries.
