A case of endoscopic ultrasound-guided drainage of pelvic absess

Diagnostic and therapeutic procedures under ultrasound endoscopy (EUS), which began with EUS-FNA, have expanded its realms. Recently, endoscopic ultrasound-guided cyst drainage (EUS-CD) are increasing its applications to various infected cavities that originated from causes other than pancreatitis. We experienced a case of EUS-CD to abscess that was not caused by pancreatitis. The improvement was seen with EUS-CD, and open surgery was avoided.
