Gallbladder and biliary tract disease in the intensive care unit.

Intensive care unit patients present a difficult challenge in the diagnosis and treatment of complications related to the biliary tract. Altered mental status interferes with the patient's ability to communicate symptoms and give a reliable physical examination. Laboratory data are often nonspecific in diagnosing complications of biliary tract disease because of the high incidence of cholestasis in intensive care unit patients. Likewise, routine radiographic evaluation has a marked decreased sensitivity and specificity in evaluating biliary tract disorders. Taken together, these factors often lead to a delay in diagnosis of biliary tract problems in the intensive care unit patient. Intervention in these patients is associated with high morbidity and mortality when compared to the ambulatory setting. This article reviews the clinical presentation, differential diagnosis, and management options of biliary tract complications in this complex patient population.
