Intrahepatic pyogenic abscesses: treatment by percutaneous drainage

Abstract

During a 6 year period, 18 liver abscesses in 12 patients were identified by computerized tomography. Five patients had presumed hematogenous seeding. Five patients previously had bilioenteric anastomoses, stents, or both to relieve obstructive jaundice. Four patients with abscesses had recent abdominal operations. Diagnosis was established by guided needle aspiration and treatment was provided by percutaneous catheter drainage. Organism-specific antibiotics were administered to all patients. Patients were evaluated for recurrence by serial computerized tomographic studies and were clinically followed up for a minimum of 15 months. Ten of 12 patients (83 percent) and 16 of 18 abscesses (89 percent) were successfully treated by percutaneous catheter drainage. Two failures required operative intervention. In summary, the low morbidity and high success rate in treating hepatic abscesses by percutaneous drainage suggests that this therapy be tried before operative intervention is considered.
