Context: In case of gall bladder disease the surgeon can efficiently handle the case if he is aware of the variations of the extra hepatic biliary apparatus without which the prognosis is unwelcome. Aims: The aim of the study is to study the volume, periotoneal relations & variations in the external morphology of the gall bladder, the knowledge of which is important for imaging of gall bladder and surgical procedures on gall bladder such as cholecystectomy and laproscopy surgery. Settings and Design: It was an observational study. The observations were made on following parameters – Capacity (Volume), morphological variations, peritoneal investment of the gall bladder, Relation of the fundus of gall bladder to the anterior margin of the liver. Methods and Material: The study was conducted on 100 gall bladders obtained from dissection of abdomen of formalin fixed cadavers . The specimen of gall bladder was observed for morphological variations on the visceral surface of the liver in the gall bladder fossa. Statistical Analysis used: Percentage for various parameters was calculated. Results: In 80% of the cases the capacity of gall bladder was ranging from 40 to 75ml. In 75% of cases the peritoneal investment on the non hepatic surface was 2/3rd to 3/4th. In 57% of cases the fundus was inframarginal & one case of bilobed gall bladder was observed. Conclusions: The gall bladder shows variations which the radiologists and the operating surgeons should keep at the back of their mind while imaging and operating for good surgical outcomes.
