Idiopathic Recurrent Acute Pancreatitis (IRAP)
Idiopathic Recurrent Acute Pancreatitis (IRAP)
The purpose of this study is to collect standardized data on the diagnosis and management of
 idiopathic (unknown cause) recurrent acute pancreatitis. The intent is to collect data for at
 least five years to obtain information regarding long-term outcomes and obtain comparative
 effectiveness data.
Inclusion Criteria:

 1. 18 years or older

 2. Able to provide consent

 3. More than one documented episode of pancreatitis (>3 fold elevation of amylase and or
 lipase with abdominal pain or with body imaging consistent with pancreatitis: need two
 of the three)

 4. Subjects with abdominal pain and enzyme elevation which is <3 fold above normal or
 absence of imaging findings: these subjects who are undergoing endoscopic
 interventions but do not fit the "classic criteria" for pancreatitis will be included
 but the analysis of data of these subjects would be done separately.

 Note: subjects with a diagnosis of pancreas divisum and or Sphincter of Oddi dysfunction
 diagnosed prior to or after entry into the study will be included in the study but their
 data will be analyzed separately because of the controversy regarding the association of
 these entities with pancreatitis.

 Exclusion Criteria:

 1. Unable to give informed consent.

 2. Definite evidence of biliary or alcoholic pancreatitis.

 3. Clear evidence of hypertriglyceridemia-induced pancreatitis (triglycerides >1,000
 mg/dl).

 4. Post-ERCP pancreatitis, drug-induced pancreatitis, or any identifiable cause for
 pancreatitis.

 5. History of pancreatic surgery.
