Background: Emphysematous cholecystitis (EC) is a form of cholecystitis with high mortality rates more commonly seen in patients with medical histories such as diabetes, hypertension, and peripheral vascular disease. The common features of these medical diseases are impaired pain perception, particularly abdominal pain, due to advanced age and peripheral neuropathies. Accurate evaluation of characteristics observed at ultrasonography, the method of first choice in the diagnosis of EC, is therefore highly important in these patients. Read More

Department of Emergency Medicine, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.

Background: Acute cholecystitis can be difficult to diagnose in the emergency department (ED); no single finding can rule in or rule out the disease. A prediction score for the diagnosis of acute cholecystitis for use at the bedside would be of great value to expedite the management of patients presenting with possible acute cholecystitis. The 2013 Tokyo Guidelines is a validated method for the diagnosis of acute cholecystitis but its prognostic capability is limited. Read More
