Necrosectomy performed by a single-use endoscope with a large operative working channel

Necrosectomy performed by a single-use endoscope with a large operative working channel A 61-year-old man with a large infected peripancreatic walled-off necrosis after acute pancreatitis [1] was managed with endoscopic ultrasound-guided placement of a lumen-apposing metal stent (20 10 mm Hot-Axios; Boston Scientific, Marlborough, Massachusetts, USA) for drainage [2, 3], followed by pneumatic dilation of the stent up to 15 mm and endoscopic necrosectomy ( Fig. 1, Video 1).After necrosectomy, two double-pigtail plastic stents, 7 Fr 7 cm and 7Fr5cm, were placed with a stent-in-stent technique ( Fig. 2).For necrosectomy we used a single-use endoscope with a large operative channel (4.2 mm) ( Fig. 3).After 2 weeks, a computed tomography scan was performed, which confirmed the resolution of WON.The stent was then removed, and the patient was discharged without any complications.
