Study of the variations of extra-hepatic biliary apparatus among the population of West Bengal
Abstract
Background: Cholecystectomy, both open and laparoscopic, are the major operations done upon upper abdomen. It is evident that, anomalies of the biliary tract are of sufficient importance to surgeons, radiologists and the gastroenterologists as well as to the anatomists from the gross anatomical and developmental point of view. Objectives: To note the various anomalies or variations in the biliary tract and their incidences. As most of the cadavers used in the present study are received from Kolkata this can be a regional study. Methodologies: Formalin-hardened specimens of liver with gall bladder from 100 adult cadavers, aged between 20-60 years were collected in the Department of Anatomy, with the help of the Department of Forensic Medicine, R.G. Kar Medical College, Kolkata between 2012-2015. Results: The average lengths of various parts of biliary apparatus was measured. A statistically significant difference between the means of lengths of common hepatic ducts in males and females was found. The mode of formation of duct system, the course and arrangement of the ducts, the mode of termination along with the related vessels were studied. Variations are more common in females than that of the males. Conclusion: Incidence of each anomaly/variations was compared with the findings of other authors. Clinical significance of anomalies/variations of extra-hepatic biliary apparatus has been discussed.
