Amoebic liver abscess: clinical presentation and diagnosis
The Australian and New Zealand Journal of Surgery
|October 1, 1980
Summary
Amoebic liver abscess should be suspected in travelers to endemic areas presenting with fever and abdominal pain. Early diagnosis via imaging and antibody tests, coupled with metronidazole treatment, minimizes surgical intervention.
Area of Science:
- Infectious Diseases
- Hepatology
- Clinical Medicine
Background:
- Amoebic liver abscess (ALA) is a significant health concern, particularly in travelers and migrants from endemic regions.
- Prompt diagnosis and effective treatment are crucial to prevent complications and reduce morbidity.
Purpose of the Study:
- To assess the clinical profiles of patients with amoebic liver abscess.
- To identify key diagnostic indicators and evaluate current treatment strategies.
Main Methods:
- Retrospective analysis of clinical data from 16 patients with ALA over a ten-year period.
- Review of patient demographics, presenting symptoms, physical examination findings, laboratory results, and diagnostic imaging.
- Assessment of treatment outcomes, including response to metronidazole and need for surgical intervention.
Main Results:
- High-risk groups include Asian migrants, farmers, and individuals with travel history to endemic areas.
- Common symptoms: fever, anorexia, weight loss, abdominal pain; physical signs: tenderness, hepatomegaly.
- Diagnostic clues: anemia, leukocytosis, elevated ESR, moderate alkaline phosphatase; confirmed by imaging (liver scan, ultrasound) and Entamoeba histolytica antibody titre.
Conclusions:
- ALA should be suspected in patients with relevant risk factors and characteristic clinical and laboratory findings.
- Radionuclide liver scan, ultrasound, and serological tests are valuable for diagnosis.
- Metronidazole is an effective treatment, significantly reducing the need for surgery.

01:30Acute Pancreatitis II: Clinical Manifestations and Management
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
