Immediate Oral Refeeding in Patients With Mild and Moderate Acute Pancreatitis: A Multicenter, Randomized Controlled Trial (PADI trial).

Objective: To establish the optimal time to start oral refeeding in mild and moderate acute pancreatitis (AP) to reduce hospital length-of-stay (LOS) and complications.

Summary Background Data: Oral diet is essential in mild and moderate AP. The greatest benefits are obtained if refeeding starts early; however, the definition of "early" remains controversial.
