Morphometry of biliar tree

Abstract

Anatomic variations of extrahepatic bile ducts may be problematic during surgical procedures. The aim of this study was to evaluate frequency of anatomic variations of the biliary tree. Morphometric characteristics of the biliary tree segments and angles between them are described in this paper. The investigation was carried out on 120 cadaveric human livers. The main methods were anatomic macro-disection and morphometry. Very high variability of length of the biliary tree segments was noticed: ductus hepaticus communis (0-39,75 mm), ductus cysticus (6,25-46,25 mm) and ductus choledochus (66,75-120,50 mm).
