The acute abdomen requires rapid and specific diagnosis because several etiologies demand urgent operative intervention. Because there is frequently a progressive underlying intra-abdominal disorder, undue delay in diagnosis and treatment may adversely affect outcome. Therefore, understanding the clinical presentation, associated laboratory and diagnostic imaging findings, and various facets of preoperative evaluation of acute abdomen is essential.
