Intra Abdominal Infections

Intra-abdominal infections comprise a heterogeneous group of conditions ranging from such relatively benign processes as acute appendicitis to conditions such as infected pancreatic necrosis, diffuse peritonitis, and intestinal infarction that are associated with substantial morbidity and mortality. They typically develop in the ambulatory patient who presents to the emergency department with abdominal pain, and the clinical manifestations of an acute abdomen. However, intra-abdominal infection can also develop in the hospitalized patient-most commonly as a complication of an antecedent disease process or invasive procedure. The presentation of these infections is often insidious and atypical, and their mortality and morbidity substantial.
