Endoscopic ultrasound‐guided infectious liver cyst drainage associated with autosomal dominant polycystic kidney disease in which percutaneous approach is impossible

Abstract

AbstractA man in his 70s on maintenance dialysis for autosomal dominant polycystic kidney disease was admitted with epigastralgia and a fever lasting for 1 week. Computed tomography showed a thickened liver cyst measuring 121 mm in the caudate lobe, suggesting infection. Percutaneous drainage was impossible because multiple liver cysts and ascites entered the puncture route. Endoscopic ultrasound (EUS) revealed a huge liver cyst with debris‐like echoes. Transgastric EUS‐guided drainage was performed, and internal and external drainage was performed without adverse events. After the procedure, the symptoms quickly improved, and the external drain was removed after 12 days. The internal drainage stent remained in place, and the patient was discharged from the hospital 53 days after the EUS‐guided drainage. EUS‐guided drainage is an effective alternative treatment for infected liver cysts where a percutaneous approach is impossible.
