Abstract
Here, we report a case of an amoebic liver abscess (ALA) successfully treated with endoscopic ultrasound (EUS)-guided liver abscess drainage (EUS-LAD). A 37-year-old male with a liver abscess was referred to our hospital due to disease progression despite receiving antibiotic therapy. Computed tomography showed an intrahepatic abscess extending into the hepatic subcapsular space. The abscess could not be punctured through the hepatic parenchyma percutaneously due to the presence of hepatic subcapsular lesions. Hence, EUS-LAD was performed via the transhepatic approach through the stomach. A 5-Fr pigtail-type nasocystic tube was inserted into the abscess through the hepatic parenchyma, with no procedure-related complications. The contents of the abscess had the appearance of anchovy paste which made us suspect an amoebic abscess; therefore, we started antibiotic therapy with metronidazole. Afterwards, serum anti-amoebic antibodies were found to be positive and the diagnosis of ALA was confirmed. Two weeks later, the size of the abscess decreased, and the patient’s clinical symptoms disappeared. Hence, the tube was removed. There were no signs of recurrence during the follow-up period. The use of EUS-LAD for pyogenic or tuberculous abscesses has been reported previously. EUS-LAD for an ALA, similar to that for other liver abscesses, is an effective alternative to percutaneous transhepatic abscess drainage or surgical treatment.
