Abstract: Human pigment gallstones are complicated in both composition and structure. We examined the cross-sectional surface of three typical pigment gallstones with scanning electron microscope, energy dispersive x-ray micro-analysis and FTIR. The results demonstrate that the composition varied with the different gallstones and the different areas in the gallstone and calcium bilirubinate complex present in these gallstones exhibit non-stoichiometric character.
