[Bacteriology of the bile in cholecystopathies. Radiological association].

A clinicobacteriological survey was undertaken in 55 patients undergoing biliary surgery, because of chronic and acute cholecystitis. Some radiological preoperative and operative aspects were analised in order to detect any relation of these aspects with biliary tract infection. The bile cultures were positive in 34,5% and 20,0% for aerobes an anaerobes microorganisms respectively. The microorganisms most frequently isolated were Escherichia coli, Pseudomonas aeruginosa, Klebsiella, Bacteroides sp and Clostridium sp, as aerobian and anaerobian. The statistical analysis showed significance between the presence of bacteria in the biliary tract and pathological operative cholangiography. It had not significance with the radiological preoperative aspects.
