A new interventional technique for percutaneous treatment of drainage-resistant liver abscess.
The objective of this case report is to describe a device that can be used as a minimally invasive alternative for the treatment of drainage-resistant liver abscess. The device uses pulse lavage to fragment and evacuate the semi-solid contents of a liver abscess. The treatment of liver abscesses consists of percutaneous drainage, antibiotics and treatment of the underlying cause. This approach can be ineffective if the contents of the abscess cavity are not liquid, and in those cases open surgery is often needed. Here, we describe for the first time a new minimally invasive technique for treating persistent liver abscesses. A patient developed a liver abscess after a hepatico-jejunostomy performed as a palliative treatment for an unresectable pancreatic head carcinoma. Simple drainage by a percutaneously placed pig-tail catheter was insufficient because of inadequate removal of the contents of the abscess cavity. After dilatation of the drain tract the persistent semi-solid necrotic contents were fragmented by a pulsed lavage device, after which the abscess healed uneventfully. The application of pulsed lavage for debridement of drainage-resistant liver abscesses proved to be an effective and minimally invasive alternative to open surgery.
