To study variations in dimensions and external morphology of cadaveric gall bladder.Materials and methods: This study was undertaken on 60 cadaveric liver and gall bladder specimens in the Department of Anatomy at Rajarajeswari Medical College and Hospital. The parameters which were measured are length and breadth at the level of neck, body & fundus of Gall bladder using the measuring tape. The shape and external variations were noted.Results: Gall bladder had length ranging between 6 and 10cm, breadth at the level of neck, body & fundus ranging between 1 to 2cm, 2 to 3.5cm, 2.5 to 3.5cm respectively. The commonest shape observed in this study was pear shaped. Conclusion:Variations in morphology of gall bladder are commonly encountered during radiological investigations and in operation theatres. Prior knowledge of morphology and morphometry of gall bladder is of utmost importance to the radiologists & laparoscopic surgeons.
