A 67-year-old man with pancreatic head cancer developed acute pancreatitis due to obstruction of the main pancreatic duct. He subsequently developed an infected walled-off necrosis (WON) (▶Fig. 1). Endoscopic ultrasound-guided transluminal drainage (EUS-TD) was performed using a 6-Fr endoscopic nasobiliary drainage catheter (SilkyPass; Boston Scientific, Tokyo, Japan) as an external drainage tube and a 7-Fr/7-cm doublepigtail plastic stent (DPS) (Zimmon biliary stent; Cook Medical, Tokyo, Japan) as an internal drainage tube (▶Fig. 2). Subsequently, the patient’s condition improved, and the external drainage tube was removed. Computed tomography (CT) performed 4 months after EUS-TD revealed that the WON had disappeared. The DPS was in place until pancreaticoduodenectomy after neoadjuvant chemotherapy and was removed endoscopically 8 months after EUS-TD because of the risk that the DPS could cause infection during adjuvant chemotherapy. At the time the stent was removed, massive arterial bleeding occurred from the fisE-Videos
