Spontaneous intra-gastric rupture of walled-off pancreatic necrosis: Endoscopic ultrasound features

Walled-off necrosis (WON) is a delayed local complication of acute pancreatitis. It is usually associated with acute necrotizing pancreatitis. It requires drainage if it is infected, associated with gastric or biliary obstruction or is painful. Asymptomatic WON are usually managed conservatively. Occasionally, WON may spontaneously fistulize into gastrointestinal lumen or may rupture into the peritoneum. We describe the endoscopic demonstration of a case of spontaneous rupture of WON into the stomach and its subsequent uncomplicated resolution. Spontaneous rupture of WON into gastrointestinal tract with uncomplicated resolution is a rare event.
