Serum amylase, pancreatic stents, and pancreatitis after sphincter of Oddi manometry.

Background: Serum amylase levels 2 hours after ERCP predict postprocedure pancreatitis. The value of serum amylase measurements after sphincter of Oddi manometry (SOM) and the effect of pancreatic-duct stent placement on serum amylase are unknown.

Methods: Records were reviewed for 88 SOM patients who had serum amylase measured 2 hours after the procedure.
