In recent years, studies have shown that early recovery of enteral nutrition has significant benefits for patients. Early recovery of oral feeding and drinking as well as early oral supplementary nutrition after surgery can promote the recovery of intestinal motor function, help maintain intestinal mucosal function, prevent postoperative flora disorder and diarrhea, shorten postoperative hospital stay, and improve postoperative anxiety of patients.This study mainly evaluated the safety of feeding 6 hours after ESWL, including the risk of post-ESWL pancreatitis and other adverse events, as well as the length of hospital stay, medical expenses, pain, etc. This research conclusion is helpful to provide more scientific and reasonable fasting time for patients after ESWL, improve patient comfort, reduce the risk of adverse events, shorten hospital stay, save medical expenses, and guide clinical practice.
The purpose of this study is to evaluate the safety of eating 6 hours after Extracorporeal Shock Wave Lithotripsy (ESWL). At present, ESWL and Endoscopic Retrograde Cholangiopancreatography (ERCP) are the routine ways to treat pancreatic duct stones. For large stones (diameter > 5mm) , ESWL often needs to be performed many times. In clinical practice, fasting for 24 hours after surgery is often used, but long-term fasting brings strong discomfort to patients. However, the consensus for initiation timing of oral nutrition has not yet been established after ESWL. Thus, we design this trial to evaluate the safety of early feeding based on 6 hours parameter instead of the consensus definition.
