Abstract

Acute appendicitis is the most common indication for emergency abdominal surgery throughout the world and a common reason for consultation in emergency departments.

In recent decades, diagnostic imaging has played a fundamental role in identifying acute appendicitis, helping to reduce the rate of blind laparotomies and hospital costs.

Given the results of clinical trials supporting the use of antibiotic therapy over surgical treatment, radiologists need to know the diagnostic criteria for complicated acute appendicitis to be able to recommend the best treatment option.

This review aims not only to define the diagnostic criteria for appendicitis in different imaging modalities (ultrasonography, computed tomography, and magnetic resonance imaging), but also to explain the diagnostic protocols, atypical presentations, and other conditions that can mimic appendicitis.

Keywords:
Appendicitis
Diagnosis
Complications
Atypical appendicitis

Computed tomography
Resumen

La apendicitis aguda es la urgencia quirúrgica abdominal más frecuente en el mundo y un motivo de consulta habitual en nuestros servicios de Urgencia.

En las últimas décadas, la imagen diagnóstica ha desempeñado un papel fundamental, lo que ha contribuido a disminuir tanto el índice de laparotomías en blanco, como los costes hospitalarios.

Debido a los ensayos clínicos que defienden el uso de antibioterapia frente al tratamiento quirúrgico convencional, debemos conocer los criterios diagnósticos de la apendicitis aguda complicada de cara a ofrecer la mejor opción terapéutica.

Esta revisión tiene como objetivo no solo definir los criterios diagnósticos de la apendicitis en las diferentes modalidades de imagen, ecografía, tomografía computarizada y resonancia magnética, sino también abordar los protocolos diagnósticos, las presentaciones atípicas y la enfermedad apendicular simuladora.
