Abstract :

Objectives: To determine and analyse clinically significant changes in hepatic lobe morphology. Materials and Methods: An observational study was conducted over 42 adult human livers which were acquired during routine dissections conducted for the first MBBS students over a period of two years (2017- 2019) at Dr. PSIMS & RF. Macroscopic thorough examination of the liver specimens was done through borders, surfaces and changes the in parenchymatous tissue was duly documented and photographed. Results: The common finding was prevalence of accessory fissures(50%) followed by pons hepatis (19%) which was identified as bridging the fissure for ligamentum teres(9.5%) and encapsulating the inferior vena cava in 9.5% of liver specimens. Accessory lobes account for a total of 16.6%,with incidence of Riedel’s lobe being 7.1%. Tongue like process of left lobe were encountered in 9.5% specimens. Unique finding in the present study was of a liver specimen which had multiple variations on visceral, anterior and superior surfaces. Conclusions: Present study comprised of multiple variations in hepatic lobe morphology, which are of great clinical significance and are interest for radiologists and gastroenterologist. Studies on liver morphology would expand the knowledge for surgical inventions and help in preventing diagnostic errors in imaging techniques.
