[Non-clostridial anaerobes in the etiopathogenesis of perivesical cholangiogenic abscesses of the liver].

The authors had under observation 318 patients who were subjected to operation and suffered from various inflammatory diseases of the bile tract; perivesical and cholangiogenic abscesses of the liver were found in 33 of them. Bacteriological tests of the contents of the abscesses demonstrated most frequently the presence of Bacteroides fragilis as a monoculture in cholangiogenic abscesses and associations of anaerobic and aerobic bacteria in perivesical abscesses. Early operation with obligatory consideration for the anaerobic component of the microflora is recommended.
