Diagnosis
To differentiate pyogenic liver abscess from amoebic liver abscess, several features such as subjects with age more than 50 years with lungs involvement, multiple liver abscesses, with amoebic serologic titres less than 1:256 can help to pin down the diagnosis of pyogenic liver abscess.[1]
- Blood CP (no leucocytosis)
- Haemoglobin estimation (anaemia)
- Serum albumin levels (falls rapidly)
- USG and CT scanning
- Guided aspiration to confirm the diagnosis
Treatment
- Antibiotics
- Percutaneous drainage under USG or CT control
- Laparotomy in intra-abdominal disease
