Abstract
|
|
|
The usefulness of microscopic examination of pure bile directly collected from the biliary tract during endoscopic retrograde cholangiography and without hormonal stimulation was evaluated in 86 patients. Cholesterol monohydrate crystal and/or
calcium
bilirubinate granule were observed in the bile of 64% of GB stones, 88% of CBD stones and 100% of IHD stones. But only 4% of non stone control group were positive crystals examinations. According to this results, microscopic examinations of bile
samples
collected during endoscopic retrograde cholangiography exhibited a sensitivity and a specificity for cholelithiasis recognition of 82.3% and 95.8%, respectively, with a positive and negative predictive value of 98.1% and 67.6%, respectively. We
conclude
that microscopic bile examinations of bile samples collected during ERC is useful to investigate in patients with suspected cholelithiasis.
