Abdominal sepsis carries a high morbidity and mortality. Intra-abdominal infectious complications are one of the most common infectious etiologies seen in critically ill patients. Approximately 30% of patients admitted to an ICU with intra-abdominal infection succumb to their illness, and when peritonitis arises as a complication of a previous surgical procedure, or recurs during ICU admission, mortality rates exceed 50%. ⋯ For diagnosis of intra-abdominal conditions using CT scanning it is optimal if patients receive both oral and intravenous contrast. An exception to the use of CT scanning is evaluation of suspected biliary pathology, which is best imaged by ultrasound. It will identify cholecystitis with or without calculus and may show changes in the gallbladder or common bile duct associated with biliary obstruction.
