Abstract

Introduction: The gall bladder is an important component of the extrahepatic biliary apparatus which presents various morphological variations, the knowledge of which serves to be important during radiological scans and surgeries. The study aims to identify few anatomical variations in the dimensions, shape and position of gall bladder which would serve beneficial in the above mentioned procedures as well as in other anatomical, clinical and research settings. Methodology: The study comprised of 30 thoroughly dissected Liver specimens obtained from 10% formalin fixed cadavers of both genders and 20 ultrasonographic scans of abdomen from the Department of Anatomy and Department of Radiology, AIMS after the requested consent from Institutional Ethics Committee and the Head of Department. The study carried out for a period of four months from February 2025 to June 2025 considered the parameters length, breadth, shape of gall bladders and length of part below or above inferior border of liver for cadaveric specimens. Results: The mean length, breadth of gall bladders in cadaveric and ultrasonographic studies were 7.82±1.29, 3.66±0.81, 6.155±0.84 and 2.39±0.59. 20 gall bladders were below the inferior margin of liver (mean length = 1.76±1.07), 5 gall bladders were above the margin (mean length = 1.68±0.86) and 5 gall bladders were at the margin. The shapes observed were pear (57%), cylindrical (37%), quadrangular (3%) and others (3%). Conclusion: The study would serve important for working surgeons and radiologists treating and scanning cases of gall bladder diseases.
