Las pruebas complementarias (hemograma, proteína C reactiva y ecografía) pueden ser normales, por lo que sería necesario realizar una laparoscopia con apendicectomía para el diagnóstico. El estudio histológico muestra cambios inflamatorios crónicos no ocasionados por otros procesos infecciosos ni compatibles con una enfermedad inflamatoria intestinal. Se presenta el caso de un niño de 12 años con episodios autolimitados de dolor abdominal agudo en el transcurso de dos años, al que se le realizó tratamiento quirúrgico con diagnóstico definitivo de apendicitis crónica.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Chronic appendicitis is a rare entity, manifested by episodes of recurrent abdominal pain located in the right iliac fossa. Complementary tests (blood count, C-reactive protein and ultrasound) may be normal, so it would be necessary a laparoscopy with appendectomy for diagnosis. The histological study shows chronic inflammatory changes, not caused by other infectious processes and not compatible with an inflammatory bowel disease. We present the case of a 12-year-old boy with self-limited episodes of acute abdominal pain during the course of two years. It was necessary a surgical treatment, with a definitive diagnosis of chronic appendicitis.]]></p></abstract>
