Human Liver Morphology: Anatomical Study about the External Aspects

Abstract

Knowledge of the anatomy of liver is a prerequisite for a complete understanding of the mechanics ofdiagnostic imaging and minimally invasive surgical approaches. So the aim of the study is to carry outthe morphological feature of right lobe, left lobe, caudate lobe, quadrate lobe and surfaces of liver. Thisis retrospective observational study done on 75 human livers irrespective of age and sex in Department ofanatomy, Smt. B.K. Shah Medical Institute and Research Center, Vadodara, Gujarat. The livers were studiedfor morphological variationsuch as accessory fissure, accessory mini lobe, Quadrant lobe with tongue likeprojection, Pons hepatis connecting left lobe with quadrate lobe, Riedel’s lobe present, Narrow and elngatedleft lobe, Absence of quadrant lobe, Absence of fissure for ligamentum teres, Bilobed caudate lobe andclassified according to Netter’s classification.Out of 75 embalmed human liver 23 (30.67%) livers werenormal and 52 (69.33%) livers shown one or more than one morphological variation of liver. Out of 52 liverfound abnormal fissures were in 23 (30.67), pons hepatis in 2 (2.66%), riedel’s lobe in 3 (4%), absence ofquadrant lobe in 1(1.33%) deep renal impression and corset constriction observed in 15 (20%) specimensof liver, diaphragmatic deep groove were observed in 1 (1.33%) specimen. The presence of knowing extralobes and fissure lies in the fact that might help to interpretation during imaging of hepatobilliary system andmay intern lead to surgical implication in operation theater.
