"In the pre-CT era, patients with an acute abdomen were often sent for urgent surgery. Contemporaneously, with the virtually ubiquitous availability of CT, some of these patients will not be operated on at all. Conversely, some patients who do not meet the traditional criteria for an "acute abdomen" will be diagnosed on imaging with conditions, such as acute appendicitis, and be sent for surgery."
"A subgroup of patients with acute abdominal pain will have a so-called acute abdomen (also known as an acute surgical abdomen). This is restricted to those with an acute presentation of abdominal pain coupled with serious morbidity, a tender abdomen and marked rigidity (involuntary guarding) on abdominal physical examination."
