A CASE OF AN INFECTED HEPATIC CYST TREATED WITH ENDOSCOPIC ULTRASOUND-GUIDED TRANSLUMINAL DRAINAGE USING A LUMEN-APPOSING METAL STENT(WITH A VIDEO)

Abstract

A 77-year-old man undergoing percutaneous endoscopic gastrostomy (PEG) for Parkinsonʼs disease developed an infected hepatic cyst (IHC), and percutaneous drainage was performed repeatedly. In this case, the enlarged and recurrent IHC caused fever and reflux from the PEG owing to compression of the gastric antrum. Because the inside of IHC was suspected to be mucinous, we determined that lumen-apposing metal stent (LAMS), which is a one-step procedure and has a large diameter, is the most suitable stent for the IHC drainage instead of conventional percutaneous drainage.

After LAMS placement using endoscopic ultrasound, purulent contents from the IHC into the stomach were confirmed, symptoms improved, and no adverse events were observed.
