Overview
This study is being done to find a faster and more accurate way to tell whether the necrosis in patients with acute necrotizing pancreatitis (ANP) has become infected. In the absence of microbiological confirmation, clinicians often have to initiate empirical antibiotic therapy for suspected pancreatic infection-a practice supported by current guidelines but one that may contribute to antimicrobial resistance. In this study, the investigators will combine metagenomic next-generation sequencing (mNGS) which could improve the accuracy of infected pancreatic necrosis (IPN) diagnosis and host transcriptional response analysis which could discriminate infectious and noninfectious inflammatory syndromes. In a prospective, multicentre, cohort study, 200 consecutive patients ≥ 14 years with ANP will be enrolled at four tertiary hospitals from Novemeber 2025 to December 2026. If validated, this single-blood approach could enable early, pathogen-directed therapy, curtail unnecessary antibiotics and expedite surgical timing in ANP.
Primary outcome measures
- Diagnostic accuracy of the integrated mNGS and host-transcription model for identification of IPN. [Time frame: through study completion, an average of 2 months]
