title: Biliary stones and bacteriae in bile study in 211 consecutive cases.
abstract: A retrospective study have been performed to investigate the correlation between stone formation and bacteriae in the bile of 211 consecutive biliary stone patients (133 females and 78 males, age ranged 1.3 to 87.0 years old, 196 cholecystolithiasis, 54 choledocholithiasis and 9 hepatolithiasis). They had undergone surgery since January 1980 to December 1987. Bile was collected to perform bacterial culture from the gallbladder and common bile duct during operation and all stones had been classified according to morphology after surgery and confirmed with component analysis if necessary. Totally 5115 stones had been collected and 20.4% had been classified as pure cholesterol stone, 16.8% as combination stone, 17.2% as mixed stone, 23.6% as calcium bilirubinate stone, 17.6% as black stone, 0.8% as calcium fatty acid stone and 3.6% as unknown. In bile culture, 84 from the gallbladder and 31 from the common bile duct were positive. Streptococci were the most frequent and followed by Klebsiella, Escherichia coli and so on. A higher incidence of positive culture was shown in calcium bilirubinate and lower incidence was shown in cholesterol stones. These results suggest that bacteriae in the bile may play a role in the formation of pigment biliary stones.
