Klebsiella complicated appendicitis

*Klebsiella* complicated appendicitis refers to an advanced form of acute appendiceal infection complicated by extension beyond the organ wall, such as perforation, periappendiceal phlegmon, abscess formation, or peritonitis, involving the opportunistic enteric Gram-negative pathogen *Klebsiella* This condition primarily affects the gastrointestinal and intra-abdominal systems, occurring across pediatric and adult populations as a clinical manifestation within the broader spectrum of complicated...

*Klebsiella* complicated appendicitis refers to an advanced form of acute appendiceal infection complicated by extension beyond the organ wall, such as perforation, periappendiceal phlegmon, abscess formation, or peritonitis, involving the opportunistic enteric Gram-negative pathogen *Klebsiella*

This condition primarily affects the gastrointestinal and intra-abdominal systems, occurring across pediatric and adult populations as a clinical manifestation within the broader spectrum of complicated intra-abdominal infections

Pathophysiologically, luminal obstruction and mucosal necrosis compromise the appendiceal barrier, allowing virulent enteric flora—including encapsulated, often beta-lactamase–producing *Klebsiella* species—to invade the peritoneal cavity and provoke marked local suppuration, severe localized or diffuse abdominal pain, systemic inflammatory toxicity, and an elevated risk of bacteremia or sepsis
