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 7 Fr × 5 cm, 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.
Our case underlines the feasibility of performing endoscopic necrosectomy of an infected WON using a new single-use endoscope, theoretically avoiding the risk of scope infection [4]. Moreover, the large working channel (4.2 mm) may reduce procedure time and avoid multiple endoscopic sessions.
