Biliary tree variations as viewed by intra-operative cholangiography - Comparing Egyptian versus international data

In our small scale study (n = 248); the more common typical biliary anatomy is observed here in Egypt at percentages nearly similar to that reported in the international literature. On the other hand, the less common variation types, show prevalence here in Egypt that are different from those reported in the international literature; a finding that could cause a higher number of bile duct injuries in laparoscopic cholecystectomies if not recognized.
