Principles and limitations of operative management of intraabdominal infections

Abstract

Operative management of intraabdominal infections still rests on the principles of elimination of focus, reduction of contamination of the peritoneal cavity, and treatment of residual infection. To control the source of contamination from a perforated viscus primary closure, exclusion or resection may be considered with respect to the severity of peritonitis and to the underlying disease. The principle of "peritoneal toilet" with complementary use of systemic and/or local antibiotics is generally accepted even if the value of aggressive debridement is still debated controversely. For the treatment of residual and the prevention of recurrent infection, closed and open lavage techniques, the left-open abdomen, and planned relaparotomy represent the major approaches in severe generalized peritonitis when the infectious focus might not be securely controlled. The values and disadvantages of different regimens are discussed, additional measures are briefly described, and an outlook on areas of further research is given.
