- Brief Summary
Recurrent acute pancreatitis (RAP) was defined as two or more occurrences of acute pancreatitis, which was associated with higher percentages of morbidities and mortalities, lower patients' life quality and increased health-care costs. Current interventions, including cholecystectomy and abstain from drinking were reported to be effective methods for preventing the recurrences of biliary and alcoholic etiologies, respectively. However, there were no effective preventions for other etiologies, such as idiopathic etiologies. Non-steroid anti-inflammatory drugs (NSAIDs), including indomethacin, diclofenac and aspirin could inhibiting the inflammatory cascade of pancreatitis. In this study, we aimed at exploring the effects of 100mg aspirin on reducing the occurrences of recurrent acute pancreatitis.

- Primary Outcome Measures
Name Time Method The mean interval between two consecutive occurrences of acute pancreatitis during follow-up 2 years Acute pancreatitis was defined as meeting two or three following items: (1) acute onset of a persistent, severe, epigastric pain often radiating to the back. (2) Serum amylase and/or lipase concentrations at least three times higher than upper limit of normal value. (3) Abdominal imaging examination results showed pancreatic inflammation.
- Secondary Outcome Measures
Name Time Method The numbers of acute pancreatitis during follow-up 2 years The numbers of pancreatitis with different severity evaluated by revised Atlanta criteria 2 years Mild acute pancreatitis, no organ failure and no local or systemic complications; Moderately severe acute pancreatitis, organ failure that resolves within 48 h (transient organ failure) and/or Local or systemic complications without persistent organ failure.
Severe acute pancreatitis, Persistent organ failure (\>48 h).The hospitalization days due to acute pancreatitis 2 years The rate of patients with chronic pancreatitis. 2 years chronic pancreatitis was defined according to the Asia\&Pacific consensus report, when meeting one of the following conditions: (1) pancreatic calcification on cross-sectional imaging; (2) pancreatic ductal changes on endoscopic retrograde cholangiopancreatography (ERCP); (3) abnormal pancreatic function test results; (d) confirmed CP on endoscopic ultrasound; and (4) histological evidence of CP.
The rate of patients with new-onset diabetes 2 years The numbers of aspirin tablets the patients actually take 2 years The mortality rate 2 years The rate of patients who had adverse events due to oral aspirin 2 years
