Core Tip
Core Tip: Rhubarb enema has shown promising intestinal-immune regulatory signals in acute pancreatitis, including a decrease in pro-inflammatory factors, a downregulation of the Th17/IL-17A pathway, an increase in IL-10, and an improvement in intra-abdominal pressure. However, recent randomized controlled studies have not shown a significant reduction in all-cause mortality at 28 days, and the actual event rate is lower than expected, with a relatively specific study population, which limits the certainty and generalizability of the conclusions. Rhubarb enema should currently be regarded as a potentially promising but unproven adjunctive intervention rather than a standard treatment that can immediately change clinical practice. Its clinical value still needs to be further verified in standardized procedures, clear stratified populations, and patient-centered hard endpoints.
