  • Title: Percutaneous drainage of hepatic abscesses: therapy does not differ for those with identifiable biliary fistula.
    Author: Bayraktar Y, Arslan S, Sivri B, Eryilmaz M, Akova M, Van Thiel DH, Kayhan B.
    Journal: Hepatogastroenterology; 1996; 43(9):620-6. PubMed ID: 8799406.
    Abstract:
    BACKGROUND/AIMS: Surgical drainage of pyogenic and amoebic hepatic abscesses has been an accepted therapy for decades. Modern imaging modalities have changed both the diagnostic and therapeutic management of many hepatic lesions, particularly abscesses. Specifically, percutaneous aspiration and drainage with either ultrasound or computed tomography guidance has been reported as an alternative treatment for hepatic abscesses in recent years. Little is known about aspiration of hepatic abscesses that communicate with the biliary tree. MATERIAL AND METHODS: Fifteen patients with hepatic abscesses treated by percutaneous aspiration and drainage are herein reported. Six had a demonstrable fistulous communication between the abscess and the biliary tree. RESULTS: During a four year period of follow-up, only two of these 15 patients experienced a recurrence. Neither had a biliary fistula complicating their abscess initially. CONCLUSIONS: Based upon this experience, it is suggested that percutaneous aspiration and drainage should be the initial treatment of choice of both pyogenic and amoebic liver abscesses even when large. Abscesses with demonstratable biliary fistulas have a larger mean volume than do those without fistulous involvement. The finding of a communication between the abscess and the biliary tree should not change this treatment approach.
