Acute acalculous cholecystitis complicating major trauma: a report of five cases.

The purpose of this study was to identify the clinical characteristics of the patients in our institution who developed acute acalculous cholecystitis (AAC) after major trauma. Data of all trauma patients who developed AAC from January 2001 through June 2006 were analyzed. Five out of 1386 (0.3%) major trauma patients were diagnosed with AAC. One out of five patients had hypotension and shock and received vasopressor treatment. Prior to the diagnosis of AAC, all patients received ventilatory support, intravenous opioid analgesia, had pneumonia, and experienced tachycardia. No specific clinical characteristic was identified in patients with AAC; however, prolonged ventilatory support, pneumonia, use of opioids, and new onset arrhythmias were seen in the majority of patients.
