[Use of infrared spectrophotometry of bile for diagnosis of cholelithiasis and predicting the chemical composition of the concrements].
Infrared spectrophotometry was applied in bile investigation from 47 cholelithiasis, 53 acalculous chronic cholecystitis and 23 control subjects. A cholelithiasis--specific shift in the absorption band appeared in the range of 900-1150 cm-1. Bile calculi removed at surgery from 110 relevant patients and bile from them were exposed to infrared spectrophotometry. The authors derived a correlation between the shape of the absorption band for bile in the range of 1500-1800 cm-1 and chemical composition of the concrement.
