Core Tip

Core Tip: Infected acute necrotic collection (ANC) is a potentially fatal disease. Endoscopic ultrasound (EUS)-guided fine-needle aspiration is recommended when the diagnosis is unclear. Endoscopic drainage is the optimal treatment for infected necrosis and is generally performed 4 wk after onset. Herein, we present a case in which an infected ANC was misdiagnosed as a pancreatic pseudocyst and was successfully treated by early EUS-guided aspiration and lavage combined with late endoscopic retrograde cholangiopancreatography catheter drainage. EUS-guided aspiration and lavage may be used as a bridge while waiting for the necrotic collection to be fully encapsulated before draining.
