    Complicated intra-abdominal infection (cIAI) often progresses to intra-abdominal sepsis (IAS), leading to rapid clinical deterioration and poor outcomes.

  • 2

    The peritoneal cavity contains a specialized immune system that enables rapid local inflammatory responses to contain infections.

  • 3

    Excessive inflammatory responses and peritoneal barrier failure can lead to systemic dissemination of pathogens, driving progression to IAS.

  • 4

    cIAI is a leading source of sepsis, accounting for 18-22% of all cases globally, with high mortality rates in advanced stages.

  • 5

    Understanding peritoneal immune dynamics is crucial for improving risk stratification and management strategies in cIAI and IAS.
