Intra-abdominal E. coli abscess

An intra-abdominal *Escherichia coli* abscess is a localized, walled-off collection of purulent exudate, necrotic debris, and microorganisms within the peritoneal cavity, retroperitoneum, or visceral abdominal organs, caused in whole or in part by the Gram-negative bacillus *E. coli* It typically arises as a complicated intra-abdominal infection following gastrointestinal mucosal disruption, viscera perforation (such as appendicitis or diverticulitis), penetrating trauma, or postoperative anasto...

An intra-abdominal *Escherichia coli* abscess is a localized, walled-off collection of purulent exudate, necrotic debris, and microorganisms within the peritoneal cavity, retroperitoneum, or visceral abdominal organs, caused in whole or in part by the Gram-negative bacillus *E. coli*

It typically arises as a complicated intra-abdominal infection following gastrointestinal mucosal disruption, viscera perforation (such as appendicitis or diverticulitis), penetrating trauma, or postoperative anastomotic dehiscence

Pathophysiologically, endotoxin-producing facultative anaerobes like *E. coli* drive early acute peritonitis and localized tissue destruction, stimulating fibrin deposition and inflammatory encapsulation to contain the infection
