Complicated E. coli peritonitis

Complicated *Escherichia coli* peritonitis is a severe, pathogen-specific intra-abdominal infection characterized by inflammation of the peritoneum that extends beyond a localized hollow viscus into the peritoneal cavity

Most commonly arising as secondary peritonitis from gastrointestinal perforation, anastomotic leak, or as an advanced complication of peritoneal dialysis and end-stage liver disease, it directly affects the gastrointestinal and peritoneal systems Clinically, it presents with severe abdominal pain, diffuse guarding or rigidity, fever, and leukocytosis, frequently progressing to systemic inflammatory response syndrome, sepsis, or septic shock without prompt surgical source control and directed ant...

Pathophysiologically, disruption of anatomical barriers or transmural bacterial translocation allows virulent *E. coli* to inoculate the peritoneal space, triggering intense neutrophilic exudation, abscess formation, and systemic endotoxemia

Clinically, it presents with severe abdominal pain, diffuse guarding or rigidity, fever, and leukocytosis, frequently progressing to systemic inflammatory response syndrome, sepsis, or septic shock without prompt surgical source control and directed antimicrobial therapy
