|Abstract:||The structure of people and organs in people vary considerably. The course and relations of the extrahepatic biliary system are highly variable. Frequency of variations often differs among various human groups, and variations seen in one population can not be assumed to apply to members of another population. Hence, this study was intended to investigate the types of variations commonly encountered among Ethiopians and analyse whether there might be sex difference in the variations. The study was carried out on 110 autopsy specimens ( 57 males and 53 females) collected from Ethiopians. The specimens containing the whole liver, stomach, duodenum, with intact lesser omentum and great vessels were meticulously dissected and any ductal or arterial variations around hepatic pedicle were recorded. One or more types of arterial or ductal variations were observed in 83 out of 110 specimens (75.5%). Ductal variations were found in 29 specimens (26.4%) and arterial variationswere encountered in 70 specimens (63.6%). Presence of Hartmann's pouch, kinking of gallbladder, long cystic duct, and accessory hepatic ducts were commonly observed surgically significant variations. The presence of aberrant hepatic and cystic arteries, abnormal origin and course of these arteries were found to be common arterial variations. Higher percentage of ductal and arterial variations were found in females than in males. Whether or not these differences have some contributions to higher rate of biliary tract diseases in females than in males has to be further investigated.|
