Hepatic Cyst Infection: Next Step When Empirical Antibiotics Fail to Resolve Fever

Clinical Scenario

This protocol applies to patients with hepatic cyst infection who present with clinical signs of infection supported by laboratory and imaging findings, and who have not responded adequately to an initial empirical antibiotic course.

When First-Line Treatment Has Failed

The preceding step used empirical antibiotic therapy — ciprofloxacin and/or a 3rd-generation cephalosporin, alone or in combination, for approximately 4–6 weeks. That approach is considered to have failed when fever does not resolve: specifically, when body temperature persists above 38.5 °C at 48 hours of empirical antibiotic use. The protocol below describes the structured next step taken after this failure.

Next-Step Approach (Partial Overview)

Because empirical antibiotics often fail to treat infected hepatic cysts, a drainage-based intervention becomes the central next consideration — with either percutaneous or surgical options evaluated based on culture results and clinical progress.

Full selection criteria, procedural sequencing, and decision points are contained in the complete structured protocol.
