Ruptured amebic liver abscess
Abstract:
Fifteen cases of extrahepatic rupture of amebic liver abscess have been reviewed. Five patients had thoracic rupture and ten had intra-abdominal rupture. Celiotomies were performed in five patients, with a preoperative diagnosis of acute appendicitis with perforation in four patients and generalized peritonitis of unknown origin in one patient. All 15 patients were treated with amebicides, including three patients with documented free intraperitoneal perforation who were not treated surgically. Twelve patients recovered uneventfully. Two patients with thoracic rupture developed secondary bacterial complications and in one case of free intraperitoneal rupture, a mistaken diagnosis of ruptured pyogenic abscess was made. Amebicidal therapy was delayed for four days. The patient died of multisystem organ failure. Amebicidal therapy is effective in the treatment of both unruptured and extrahepatic rupture of amebic liver abscess. Surgery should be required only for secondary bacterial complications.
Insights
Amebicidal therapy effectively treats extrahepatic rupture of amebic liver abscesses. Surgery is typically only needed for secondary bacterial infections, not the rupture itself.
Area of Science:
- Hepatology
- Infectious Diseases
- Surgical Gastroenterology
Background:
- Amebic liver abscess (ALA) is a common parasitic infection, particularly in tropical regions.
- Extrahepatic rupture of ALA, though less common, presents significant diagnostic and management challenges.
- Understanding rupture patterns and treatment outcomes is crucial for patient survival.
Observation:
- This review analyzed 15 cases of extrahepatic ALA rupture.
- Ruptures were categorized as thoracic (5 cases) or intra-abdominal (10 cases).
- Five patients underwent celiotomy, often with misdiagnoses like appendicitis or generalized peritonitis.
Findings:
- All 15 patients received amebicidal therapy.
- Three patients with free intraperitoneal perforation were managed non-surgically with amebicides alone.
- Twelve patients recovered without complications; two with thoracic rupture developed bacterial issues, and one patient with delayed amebicidal therapy died.
Implications:
- Amebicidal therapy is highly effective for both unruptured and ruptured ALA.
- Surgical intervention should be reserved for managing secondary bacterial complications.
- Accurate diagnosis and timely amebicidal treatment are paramount for favorable outcomes in ruptured ALA.
