“…For many years clinicians have examined bile collected from patients by a tube passed perorally into the duodenum (the Meltzer-Lyon test) (13,(19)(20)(21)(22)(23)(24)(25)(26)(27). When gallbladder bile contains cholesterol crystals or calcium bilirubinate granules in moderate to large amounts, there is a strong correlation with the presence of gallstones in the gallbladder or some other abnormality, such as cholesterolosis (19)(20)(21). Even though supersaturation of bile with cholesterol is very common in humans during fasting (281, cholesterol crystals usually do not develop except in those with gallstone disease 129).…”

To investigate the origin of echoes from "biliary sludge," concentrated bile and bile from 5 patients with ultrasound findings of biliary sludge were examined in a tissue-equivalent phantom before and after filtration through progressively smaller pore sizes. Filtration converted echogenic bile to echo-free bile. Examination of the filtration residue by light microscopy established that the source of echoes in biliary sludge was particles, predominantly pigment granules, with lesser amounts of cholesterol crystals. Partial chemical characterization by determination of vulnerability to different solvents verified that the sludge was mainly calcium bilirubinate.
