Chemical composition of gallbladder sludge in patients after marrow transplantation.

Abstract

We conclude that gallbladder sludge in patients after marrow transplantation consists primarily of "unmeasurable residue," calcium bilirubinate, and a calcium-binding protein. Cholesterol crystals are almost absent. We conclude that formation of gallbladder sludge in these patients could serve as a model for studying the pathogenesis of pigment gallstones.
