Principles and limitations of operative management of intraabdominal infections
1Department of Surgery, University of Freiburg, Federal Republic of Germany.
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.
Insights
Managing intra-abdominal infections involves eliminating infection sources, reducing peritoneal contamination, and treating residual infection. Surgical strategies like peritoneal lavage and planned relaparotomies are key for severe cases.
Area of Science:
- Surgical Management
- Infectious Diseases
- Critical Care Medicine
Background:
- Intra-abdominal infections (IAIs) are a significant cause of morbidity and mortality.
- Effective management hinges on source control, contamination reduction, and treating residual infection.
Purpose of the Study:
- To review current operative management principles for intra-abdominal infections.
- To discuss various surgical techniques and their associated benefits and drawbacks.
Main Methods:
- Review of established surgical principles for intra-abdominal infections.
- Discussion of techniques including primary closure, exclusion, resection, peritoneal toilet, and lavage.
- Analysis of approaches for severe generalized peritonitis: open/closed lavage, open abdomen, and planned relaparotomy.
Main Results:
- Source control via closure, exclusion, or resection depends on peritonitis severity and underlying disease.
- "Peritoneal toilet" with antibiotics is standard, though aggressive debridement remains debated.
- Lavage techniques, open abdomen, and relaparotomy are crucial for uncontrolled severe peritonitis.
Conclusions:
- Operative management of IAIs requires a multi-faceted approach focusing on source control and infection eradication.
- The choice of surgical strategy should be tailored to the individual patient's condition.
- Further research is needed to optimize treatment regimens and address controversial aspects like debridement.
