Clinical Trial Summary

Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication with high costs, significant morbidity and even mortality. The major mechanisms of PEP is the papillary edema which is caused by manipulations during cannulation or endoscopic treatment. The papillary edema may cause temporary outflow obstruction of pancreatic juice, and then increase ductal pressure, resulting in the occurrence of pancreatitis. Nitroglycerin can reduce the Oddis sphincter tension, the internal pressure of the biliary tract and the pancreatic duct. Therefore, it is widely used in clinical to prevent and treat pancreatitis. Many studies found nitroglycerin might be effective in preventing PEP. And topical application of epinephrine on the papilla may reduce papillary edema by decreasing capillary permeability or by relaxing the sphincter of Oddi. There are reports that epinephrine sprayed on the papilla may be effective to prevent PEP.

The investigators therefore designed a prospective randomized trial to determine whether routine using papillary epinephrine spraying in patients received octreotide can reduce post-ERCP pancreatitis.
