Safety of 6 Hours Feeding After Extracorporeal Shock Wave Lithotripsy of Pancreatic Stone

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.

Inclusion Criteria:Patients with chronic pancreatitis who completed ESWL.Exclusion Criteria:Readmitted to the hospital during enrollment of the study;Cannot eat or rely on jejunal nutrition tube to give total parenteral nutrition for various reasons;With acute pancreatitis, perforation, infection, bleeding, steinstrasse and other complications and other serious clinical adverse events within 6 hours after ESWL;Suspected or confirmed malignancyPancreatic ascites;Coagulation dysfunction;Taking chemotherapy drugs and immunosuppressants for a long time;Acute pancreatitis exacerbation or acute exacerbation of chronic pancreatitis (including biliary pancreatitis);Pregnant or breastfeeding women;Patients who refused to participate in the study.
