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

Phase 3

Recruiting

• Conditions: Pancreatic Diseases
• Interventions: Other: Placebo; Drug: Ondansetron

• Registration Number: NCT06861010
• Lead Sponsor: Tanta University

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Control group	Placebo	the patients will receive placebo tablet 2 h before ERCP
ondansetron group	Ondansetron	the patients will receive placebo tablet 2 h before ERCP.

Primary Outcome Measures

Name	Time	Method
The primary outcome that will be measured is the development of pancreatitis after the procedure according to consensus criteria	24 hours	The primary outcome that will be measured is the development of pancreatitis after the procedure according to consensus criteria. 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
