Interventional radiology-guided percutaneous drainage of liver abscesses with concomitant use of antibiotics has been the conventional approach for the treatment of liver abscesses. Hepatic abscesses refractory or not amenable to percutaneous drainage have been treated with surgical drainage, either via laparoscopic or open laparotomy techniques. The aim of this review was to evaluate the technical feasibility and efficacy of endoscopic ultrasound (EUS)-guided drainage of liver abscesses. A literature review was performed to identify the studies describing the technique. In this review article we have summarized case series or reports describing EUS-guided liver abscess drainage. The indications, techniques, endoprostheses, limitations and complications reported are discussed. A total of seven cases have been described so far in the literature which included patients with failed conventional treatment modalities. The EUS-guided drainage technique involves puncturing the abscess using endosonography to gain access, passing a guidewire followed by tract dilation and placement of an endoprosthesis for drainage. Studies have reported 100% technical and clinical success rates in selected cases. No complications were reported. EUS-guided drainage of liver abscesses can be a safe and effective alternative approach in the management of liver abscesses in selected patients.
