Description

Acute pancreatitis is one of the most common causes of acute hospital admission, which is unpredictable and contributes to high health-care costs even death. Recurrent acute pancreatitis is defined as two or more discrete episodes of acute pancreatitis, and has an estimated annual incidence of 8-10 per 100 000. Cholelithiasis, alcohol and Hyperglyceremia are the most commonly recognized causes of acute pancreatitis. About 80% of RAP patients can be identified through routine investigations identify (include proper history, physical examination, CT, MRI, endoscopic ultrasound); however, in up to 20% of cases whose cause remains unclear are known as idiopathic RAP. For RAP patients with clear cause, removal of the cause can effectively reduce or prevent recurrence. For patients with idiopathic RAP, the treatment options are not clear and have been subject to debate. At present, the natural course, outcome and therapeutic effect of RAP is still not clear. Therefore, the prospective cohort can clarify the clinical characteristics of RAP more comprehensively and deeply and to accumulate evidence for treatment.
