The investigators are interested in performing a detailed examination of the pancreas via EUS (Endoscopic Ultra Sound)for patients referred for a non-pancreatic condition. The hypothesis is to make a statistical determination of how many pancreatic cysts the investigators discover incidentally.

The prevalence of incidental pancreatic cysts discovered during EUS. (see data tables)

Inclusion Criteria:

Exclusion Criteria:

• Any known history or evidence of the following from any previous imaging study: pancreatic cyst, solid mass, suspected pancreatic mass, dilated main pancreatic duct
• Previous surgical resection of any portion of the upper GI tract such as Billroth II that would not permit complete EUS exam of the pancreas
• Laboratory and/or clinical evidence of ongoing acute pancreatitis
• Previous pancreatic surgical resection
• Pregnancy
• Incarceration
• High risk for sedation
• Coagulopathy and/or thrombocytopenia
• The patients underwent a complete EUS examination of the pancreas.
