PURPOSE: Liver abscess occurs in most patients with biliary stents or bypass undergoing chemoembolization despite the use of standard prophylactic antibiotics. The present study was conducted to investigate the efficacy of an aggressive prophylactic regimen to prevent abscess in such patients. MATERIALS AND METHODS: Between November 2002 and July 2005, 16 chemoembolization procedures were performed in seven patients who had undergone biliary intervention. Prophylaxis was initiated with levofloxacin 500 mg daily and metronidazole 500 mg twice daily 2 days before chemoembolization and continued for 2 weeks after discharge. A bowel preparation regimen was given with neomycin 1 g plus erythromycin base 1 g orally at 1 p.m., 2 p.m., and 11 p. m. the day before chemoembolization. With the Fisher exact test, the incidence of infectious complications was compared with previously reported data for patients with and without earlier biliary intervention who had received standard prophylaxis. RESULTS: Liver abscess occurred in two of seven patients after two of 16 procedures. Previously reported incidences were six of seven patients (P=.103) and six of 14 procedures (P=.101) among patients with previous biliary intervention receiving standard prophylaxis and one of 150 patients (P=.005) and one of 383 procedures (P=.004) among patients with no previous biliary intervention. CONCLUSIONS: There was a trend toward a lower rate of abscess formation among patients at high risk who received more aggressive antibiotic prophylaxis, but the difference did not reach statistical significance. The rate of infection remained significantly higher than among patients without previous biliary intervention.
