'Pipe-organ'-like retroperitoneal drainage in severe necrotizing pancreatitis.

Infected pancreatic necrosis is a severe complication of acute pancreatitis; this complication is the major cause of death. We used the 'pipe-organ' -like retroperitoneal drainage, which is usually used in the management of open pelvic fracture, successfully in a patient with severe infected pancreatic necrosis. This procedure can avoid gastrointestinal fistula and local bleeding without necessitating surgery.
