Clinical characteristic of amoebic liver abscesses in the North of Iraq.
OBJECTIVE
The purpose of the study was to find out the clinical characteristic of amoebic liver abscesses in this area, the simplest method for diagnosis and to determine the effectiveness of treatment by metronidazole therapy proved by disappearance of symptoms and regression in the size of the abscesses by ultrasound.


METHODS
We studied prospectively all cases of suspected liver abscesses admitted to our unit over 2 years (1990 & 1991). A special case sheet was prepared. Daily follow up of patients was carried out in hospital for at least 10 days. Patients were later followed up by ultrasound after discharge. We compared the rate of infection from the hospital records over the last 9 years up to the end of 1998.


RESULTS
We found the clinical features of the disease similar to those mentioned in essential text books of medicine, except that pain is not always epigastric while fever may be absent and hepatomegaly is not marked. Ultrasound is a simple, cheap diagnostic test, which is available. Metronidazole is an effective treatment and none of the patients required an invasive method for diagnosis or treatment. None had secondary bacterial infection.


CONCLUSIONS
Amoebic liver abscess if untreated is a grave disorder. We concluded that recognizing the disorder clinically and proving it by ultrasound is the main method for diagnostic confirmation. Following the hospital records of the last 9 years, it seems that the rate of infection is declining in this area.
