Evaluating the Safety and Efficacy of Ondansetron in the Prevention of Post Endoscopic Retrograde Cholangiopancreatography Pancreatitis

Endoscopic retrograde cholangiopancreatography (ERCP (, a key tool that is used in diagnosis and treatment of pancreato-biliary diseases. Post-ERCP pancreatitis (PEP) is the most common and serious complication that can occur following this procedure and can lead to significant morbidity and mortality. A variety of patient-related and procedure-related factors have been associated with higher rates of PEP.

Briefly in this criteria PEP will be diagnosed if the Patient met two of the three following criteria after ERCP: new onset or increased abdominal pain consistent with acute pancreatitis, pancreatic enzyme elevation to at least 3 times the upper limit of normal at 24 hours after the procedure, and the necessity for new or continued hospitalization for at least 2 nights
