Summary
Unruptured amoebic liver abscesses presenting as acute abdomen require emergency surgery. Diagnosis relies on clinical signs, aspirate characteristics, and treatment response, not solely on parasite identification.
Area of Science:
- Hepatology
- Infectious Diseases
- Surgical Gastroenterology
Background:
- Unruptured amoebic liver abscess (ALA) is typically not a surgical emergency.
- Six cases of unruptured ALA presented with acute abdominal symptoms at University College Hospital, Ibadan.
Observation:
- Patients underwent emergency exploratory laparotomy due to acute abdomen presentations.
- Initial diagnoses included perforated duodenal ulcer, intestinal obstruction, cholecystitis, and appendicitis.
- Post-surgery, patients experienced prolonged draining sinuses (1-5 months).
Findings:
- The "abscess" content was necrotic liver tissue, lacking Entamoeba histolytica trophozoites or cysts.
- Diagnosis was confirmed via clinical presentation, characteristic "anchovy" or chocolate-colored liver aspirate, response to anti-amoebic therapy, and serological studies.
Implications:
- Emergency laparotomy for unruptured ALA can lead to complications like persistent draining sinuses.
- Accurate diagnosis of ALA requires a combination of clinical, aspirate, therapeutic, and serological evidence.
- Highlights the importance of considering ALA in differential diagnoses for acute abdomen, even when unruptured.
