Amebic liver abscess. The surgeon's role in management

Area of Science:

• Hepatology
• Infectious Diseases
• Surgical Gastroenterology

Background:

• Hepatic amebic abscess is a significant cause of acute abdominal illness.
• Diagnosis and management can be challenging, especially in metropolitan populations.
• Understanding patient demographics and abscess characteristics is crucial for effective treatment.

Purpose of the Study:

• To review the clinical presentation, diagnosis, and management of hepatic amebic abscesses.
• To identify demographic and clinical factors associated with amebic liver abscess.
• To evaluate the efficacy of medical and surgical interventions.

Main Methods:

• Retrospective case series of 71 patients with hepatic amebic abscess.
• Analysis of diagnostic modalities including ultrasonography, radionuclide scan, and laparotomy.
• Review of treatment outcomes with metronidazole and surgical intervention.

Main Results:

• Most patients were young, male, and of Mexican origin, with half having coexistent medical diseases.
• Diagnostic imaging (ultrasonography, radionuclide scan) achieved accurate diagnosis within 24 hours in most cases.
• Metronidazole was effective initial therapy for 64 patients; 20% required surgery for ruptured abscesses or coexistent conditions.

Conclusions:

• Amebic liver abscess should be considered in febrile patients with right upper quadrant pain in metropolitan areas.
• Rapid diagnosis is achievable with imaging techniques.
• While medical therapy is often successful, surgical intervention remains necessary for a subset of patients, particularly those with complications.
