NCT07248527

Brief Summary

This study examines a new blood test called ICIS, which may help detect infections earlier after pancreatic surgery. Patients will have routine blood samples taken during their hospital stay, with no extra procedures required. By tracking how ICIS changes over time, investigators aim to improve early infection detection, support safer recovery, and reduce postoperative complications.
