Core Tip

Core Tip: This was a multicenter, prospective, randomized controlled study, which aimed to assess the efficacy and safety of the external use of mirabilite to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) in children. Our study showed that the external use of mirabilite can reduce the incidence of PEP, relieve post-procedural pain, and regulate inflammatory mediator expression to reduce the inflammatory response. This study suggests that the external use of mirabilite is a safe, effective, and more acceptable option for the prevention of PEP prophylaxis in pediatric patients.
