[A microbiological validation and criteria for the efficacy of the use of CO2 and YAG lasers in the surgical treatment of cholecystitis].

A considerable frequency of infected bed of the gallbladder in different forms of cholecystitis was established, the anaerobic microflora being inoculated more often. A direct dependence of the frequency of infecting the bile and gallbladder bed on the patient's age and duration of having chronic cholecystitis was shown. The sterilization and prevention of reinfection of the gallbladder bed after the removal of it can be achieved by the laser irradiation of the total bed surface inspite of the absence of clear symptoms of acute inflammation of the bladder and the surrounding tissues, and the cleansing should be performed after the manipulations on extrahepatic bile ducts are completed.
