Experience with aspiration in cases of amebic liver abscess in an endemic area.
The study presented here was performed to evaluate the need for aspiration in patients with amebic liver abscess (ALA). Patients older than 12 years with a diagnosis of ALA based on clinical features, ultrasound results, and positive amebic serology were included in the study (n=144). Serological testing was performed to detect the presence of immunoglobin G antibody against Entamoeba histolytica, and a value of more than 0.4 optical density units was considered positive. All patients were given intravenous metronidazole (500 mg every 8 h) and their clinical progress and need for abscess aspiration was documented. Fever, pain in the upper abdomen, and tender hepatomegaly was seen in 133 (92.3%), 128 (88.8%), and 144 (100%) patients, respectively. Multiple abscesses were seen in 40 (27.7%) patients. Six (4.1%) patients died. Seventy-one (49.3%) patients responded to metronidazole alone. A total of 73 (50.69%) patients required aspiration of the abscess. This study shows that almost 50% of the patients with amebic liver abscess failed to respond to metronidazole and required aspiration.
