Liver abscesses are a risk after hepatic chemoembolization, particularly in patients with prior bilioenteric anastomosis. Standard antibiotic prophylaxis may not prevent abscesses in these high-risk cases.

Area of Science:

  • Hepatology
  • Interventional Radiology
  • Oncology

Background:

  • Hepatic chemoembolization is a common treatment for liver tumors.
  • Liver abscess is a potential complication following this procedure.
  • Understanding risk factors is crucial for patient management.

Purpose of the Study:

  • To determine the incidence of liver abscess after hepatic chemoembolization.
  • To identify risk factors associated with liver abscess formation.

Main Methods:

  • Retrospective analysis of 397 chemoembolization procedures in 157 patients.
  • Patients received standard prophylactic antibiotics.
  • Statistical analysis (chi-squared, Fisher exact test) identified risk factors.

Main Results:

  • Liver abscess occurred in 4.5% of patients (2.0% of procedures).
  • A history of bilioenteric anastomosis significantly increased abscess risk (OR 894, P <.0001).
  • Neuroendocrine tumors and gastrointestinal sarcomas were associated with higher abscess rates.

Conclusions:

  • Bilioenteric anastomosis is the primary risk factor for liver abscess post-chemoembolization.
  • Current antibiotic prophylaxis regimens are insufficient for patients with prior bilioenteric anastomosis.
  • Further strategies are needed to mitigate abscess risk in these patients.
