Postoperative intra-abdominal sepsis

Postoperative intra-abdominal sepsis carries a high mortality. Diagnosis by clinical examination is often difficult, and imaging techniques may be helpful. Diagnostic laparotomy should be considered early, even in the absence of localizing signs. The use of aggressive surgical techniques may improve prognosis. The timing of surgical intervention is as important as the technique. Early diagnosis and treatment is particularly crucial in critically ill patients.
