In 20 patients treated on account of advanced cholecystitis, inflammations of the biliary pathways and liver a cephalosporin of the third generation, cefoperazone, was administered within the framework of antimicrobial treatment after surgery or after endoscopic intervention. In the laboratory investigation of the study in isolated bacteria minimal inhibitory concentrations and serum, biliary and tissue levels of cefoperazone were assessed.
The minimal inhibitory concentrations in the assessed bacteria were several times lower than the levels assessed in serum, bile and the wall of the gallbladder. The infection was eradicated in 20 patients.
Seventeen patients were cured (85%).
