Acute Abdomen in the Modern Era

Acute abdominal pain is one of the most common symptoms in patients presenting to the emergency department and accounts for 5 to 10% of all emergency department visits. Pathophysiological conditions that lead to surgical interventions in such patients are mainly gastrointestinal obstruction, hemorrhage, ischemia, and viscus perforation. Acute abdominal pain can be diffuse or localized (i.e., quadrant-based epigastric pain or pain in the right upper quadrant, left upper quadrant, right lower quadrant, or left lower quadrant)2,4,6 and is associated with but not limited to the following disease processes: perforated viscus, peptic ulcer disease, mesenteric ischemia, acute cholecystitis, appendicitis, diverticulitis, pancreatitis, and intraabdominal hemorrhage. The need for emergency general surgery is an independent risk factor for postoperative complications and death, indicating the severity of the condition. Therefore, timely diagnosis of acute abdominal emergencies is essential. From antiquity to modern times, medical students have been taught that the history and the physical examination are the central components in the evaluation of acute abdominal pain.
