Early Enteral Nutrition in Severe Acute Pancreatitis

Early Enteral Nutrition in Severe Acute Pancreatitis

to compare different time points for enteral nutrition in SAP patients

There is increasing evidence that indicates Early Enteral Nutrition（EEN） may be associated with improved outcome in acute pancreatitis patients. However, some SAP patients failed to EEN. The researchers of this study aim to investigate the opportunity of EEN on the clinical outcomes of SAP patients.
