In Canada, Acute Care Surgery (ACS)
is defined as the urgent assessment and treatment of non-trauma general surgery emergencies. This model of health care delivery optimizes the treatment of intra-abdominal surgical crises. In academic and community hospitals, surgical emergencies are a common reason for hospital admission. Acute general surgery conditions include, but are not limited to, appendicitis, cholecystitis, diverticulitis, pancreatitis, intestinal obstruction, intestinal ischemia, intra-abdominal sepsis, incarcerated hernias, and perforated viscus.
