Tertiary peritonitis: A disease that should not be ignored.

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Surgical Infections

Background:

• Intra-abdominal infections encompass uncomplicated and complicated forms, with peritonitis being a severe complication.
• Peritonitis is stratified into primary, secondary, and tertiary forms, with tertiary peritonitis being the most severe and less common.
• Tertiary peritonitis is characterized by recurrent infection post-secondary peritonitis, complex pathogenesis linked to peritoneal immune response, and significant mortality.

Purpose of the Study:

• To highlight the severity and complex pathogenesis of tertiary peritonitis.
• To emphasize the increased risk of sepsis and multiple organ failure in persistent peritonitis.
• To discuss the diagnostic and therapeutic challenges, including multidrug-resistant pathogens and the importance of early intervention.

Main Methods:

• Review of the pathogenesis and clinical characteristics of tertiary peritonitis.
• Analysis of microbiological profiles and prevalence of multidrug-resistant pathogens.
• Evaluation of diagnostic tools, including clinical scores for intensive care unit (ICU) admission.
• Discussion of therapeutic strategies, focusing on immediate management and recurrence prevention.

Main Results:

• Tertiary peritonitis is a severe condition with complex pathogenesis, often leading to sepsis and multiple organ failure.
• A distinct microbiological profile and a high prevalence of multidrug-resistant pathogens characterize tertiary peritonitis.
• Clinical scores can aid in early diagnosis during ICU admission, facilitating timely management.
• Effective management relies on prompt control of the infectious focus and initial antimicrobial therapy.

Conclusions:

• Tertiary peritonitis poses a significant threat, particularly in patients with risk factors, contributing to hospital mortality.
• Early diagnosis through predictive clinical scores and immediate, appropriate antimicrobial therapy are essential for successful treatment.
• Preventing recurrence through effective infectious focus control and peritoneal drainage is critical for patient outcomes.
