Variations In The External Morphology Of Gall Bladder: A Cadaveric Study In South Coastal Population.

Abstract

Background:The extra hepatic biliary apparatus usually presents with some anatomical or embryological variations which go unnoticed and are commonly encountered during some radiological investigations or in operation theaters. Such variations of the morphology of Gall bladder have been well documented in the literature for many years but a detail morphological study of variations of the gall bladder and its incidence is very rare. In this era of quick results, increasing use of diagnostic and interventional procedures makes it important to study variations of gall bladder morphology. Most of the interventional procedures in this modern era are done laparoscopically and there is tremendous increase in the number of laparoscopic cholecystectomies. So, sound knowledge of possible variations in morphology of gall bladder is important. Materials and Methods: This study was undertaken on 100 cadaveric liver and gall bladder specimens in terms of length, maximum transverse diameter, and shape, external variations of gall bladder, Interior and length of gall bladder below the inferior border of the liver. Results: Gall Bladder had length ranging between 3.3 and 10 cm, transverse diameter between 2.0 and 5.0 cm. The commonest shape observed in this study was pear shaped in 80% of cases. The length of gall bladder below the inferior border of liver varied between 0.4 and 2.5 cm. Conclusion:The growing importance of such variations, lie not only from the point of biliary disease but also with respect to the various invasive techniques in the diagnosis and treatment of gall bladder and extra hepatic bile duct disease.

Morphometric Study of Gallbladder in Cadavers

“…With the increasing use of interventional and diagnostic procedures, as well as laparoscopic cholecystectomy, the study of variation in the external morphology of the gallbladder has become increasingly important (6). The present study describes the different anatomic variations of human gallbladder and its clinical importance.…”
