[Microbiological and histologic correlations in inflammatory gallbladder disease (author's transl)]

In a hospital population of 243 patients undergoing surgery for gallstones, inflammatory alterations were seen in 177 cases. The search for bacteria was positive in 33 cases. Thus, more than 80 per cent of the cholecystitis cases were abacterial. Under the age of 50, micro-organisms were found in 4.5 per cent only, and in 37 per cent of patients above fifty. In 11 cases of acute cholecystits no bacteria were found at all. Antibiotic treatment is justified in high-risk patients.
