BACKGROUND: Endoscopic procedures can develop bacteremia. Patients with chronic liver disease are more predisposed to undergo bacteremia and infections because they are immunocompromised. AIMS: The purpose of this study was to determine the incidence of bacteremia in cirrhotics submitted to endoscopic variceal ligation. METHODS: Three groups of 40 patients each were studied. One group was made up of patients with cirrhosis who were submitted to ligation, a second group was composed of cirrhotics who underwent esophagogastroduodenoscopy only, and a third group was composed of patients without liver disease who underwent esophagogastroduodenoscopy. Blood was sampled from all patients for culture, both in aerobic and in anaerobic mediums, immediately before endoscopy and at 5 and 30 minutes after its completion. RESULTS: Blood culture was positive in 6 samples. In 4 of these, the bacteria (Staphylococcus hominis hominis, Staphylococcus auricularis, Acinetobacter lwoffii, and coagulase-negative staphylococcus) were isolated before the endoscopic procedure and thus were considered as contamination. In the ligation group, a streptococcus of the viridans group was isolated 5 minutes after the procedure, and in the cirrhosis without ligation group, a Staphylococcus epidermidis was isolated at 30 minutes. None of the patients showed clinical evidence of infection. CONCLUSIONS: The bacteremia incidence in cirrhotic patients submitted to variceal ligation was 2.5%, showing no difference from the control groups.
