Association between enteral nutrition formula types and initial time with prognosis in moderately severe and severe acute pancreatitis: A 5-year retrospective multi-center study

Therefore, an optimal EN strategy can be summarized. First, the selection of the EN formula should be based on the patients' basic conditions, especially glucose level, rather than on the pancreatic rest theory. Second, the conversion from SP to IP made it easier for patients to tolerate the EN and decreased insulin use. Finally, the proper opportunity to commence EN was considered to be 3-5 days after SAP onset.
