Abstract

Sixty-four consecutive cases of hepatic abscess diagnosed over a 6-year period and all treated by ultrasound-guided percutaneous needle aspiration and systemic antibiotics were retrospectively reviewed to ascertain factors influencing the outcome in these patients. The 64 patients had in total 101 liver abscesses which averaged 4.7 cm in diameter. Two patients (3.1%) required surgery for associated biliary tract disease. Five patients (7.8%) died from septicaemia and/or serious condition or malignancy. The remaining 57 patients (89.1%) were successfully treated--45 cases (70.3%) showed fully-resolved abscess/es after a mean period of 69.9 days after initial aspiration; 12 patients (18.8%) showed markedly-shrunken abscess cavity size over an average of 30.7 days and all were asymptomatic on discharge from hospital. No correlation was demonstrated between number of abscesses and successful patient recovery--42 of 46 patients (91.3%) with solitary hepatic abscess recovered, 6 of 8 patients (75.0%) with 2 abscesses and 9 of 10 patients (90.0%) with more than 2 abscesses were successfully treated. No correlation was detected between abscess size and number of aspirations required, majority of abscesses (73.3%) requiring no more than...Continue Reading
