Core Tip
Core Tip: Endoscopic drainage of walled-off necrosis (WON) is still a challenge due to stent-associated problems. Endoscopic gastric fenestration may be an innovative alternative intervention for WON adherent to the gastric wall, and might outperform lumen-apposing metal stent drainage, with lower cost and no stent-related complications. The challenge is to select appropriate fenestration. We established some characteristics for suitable fenestration sites: Computed tomography: Intimate contact between the stomach and encapsulated WON without clear layers; endoscopy: Intense inflammation (edema, erosion or ulceration) of gastric mucosa; endoscopic ultrasound: Modest abutment (generally < 1 cm) of the stomach and WON without clear layers.
