RESUMEN
Helicobacter pylori (
H. pylori) es una bacteria Gram-negativa, microaerofílica con forma espiral. Reconocida como causa importante de gastritis, úlcera duodenal y gástrica, adenocarcinoma gástrico y linfoma MALT a nivel mundial. La prevalencia de
H. pylori es de 70 a 90% en países en desarrollo y de 25 a 50% en países desarrollados. Existen múltiples métodos diagnósticos en la detección de
H. pylori; los cuales incluyen métodos invasivos y no invasivos. Actualmente, el estudio histológico de las biopsias tomadas por endoscopia (método invasivo) es el estándar de referencia; con una sensibilidad y especificidad de 100%. Las pruebas no invasivas tienen la ventaja de ser procedimientos más aceptados por los pacientes, de menor costo y menor riesgo. Razones por las que se desea conocer la utilidad de los métodos no invasivos para el diagnóstico de
H. pylori, en comparación con los métodos invasivos.
