Clinical Outcome of Endoscopic Ultrasound-Guided Liver Abscess Drainage Using Self-Expandable Covered Metallic Stent (with Video)

Background Percutaneous drainage (PCD) is now the first-line drainage method for liver abscess because of its minimal invasiveness and high technical success rate. However, this procedure has several disadvantages, such as extra-drainage and self-tube removal. Recently, EUS-guided liver abscess drainage (EUS-AD) has been developed. However, only a few reports of EUS-AD have been reported. In addition, the clinical benefits of PCD and EUS-AD have not been reported.
