Intraabdominal abscess causes

The causes of intraabdominal abscess overlap those of peritonitis and, in fact, may occur sequentially or simultaneously. Appendicitis is the most frequent cause of abscess. 

Table 42-1 summarizes many of the potential causes of bacterial peritonitis. The causes of intraabdominal abscess somewhat overlap those of peritonitis and, in fact, both may occur sequentially or simultaneously. Appendicitis is the most frequent cause of abscess. Intraabdominal infection results from entry of bacteria into the peritoneal or retroperitoneal spaces or from bacterial collections within intraabdominal organs. When peritonitis results from peritoneal dialysis, skin surface flora are introduced via the peritoneal catheter. 

The primary goals of treatment are correction of the intraabdominal disease processes or injuries that have caused infection and drainage of collections of purulent material (abscess). A secondary objective is to resolve the infection without major organ system complications (e.g., pulmonary, hepatic, cardiovascular, or renal failure) or adverse drug effects. Ideally, the patient should be discharged from the hospital with full function for self-care and routine daily activities.
