[Infection as a risk factor in biliary system surgery].

Infection of the biliary system in which one of the signs is the presence of bacteria in bile is connected with an increase of incidence of postoperative complications especially in elderly people. Therefore, early diagnosis of infections and their prophylaxis and treatment are an important aspect of surgical management which is particularly significant in view of large number of patients with acute and chronic cholangitis. Proper selection of the operation time and the use of antibiotic therapy with adequate utilization of even broader spectrum of antibiotics may be of decisive importance for effective treatment.
