Acute Cholecystitis: History
The most common presenting symptom of acute cholecystitis is upper abdominal pain.Signs of peritoneal irritation may be present, and in some patients, the pain may radiate to the right shoulder or scapula.
Although the pain may initially be described as colicky, it becomes constant in virtually all cases.
Nausea and vomiting are generally present, and patients may report fever.
Cholecystitis is differentiated from biliary colic by the persistence of constant severe pain for more than 6 hours.
