Abstract
[spa] La infección por Helicobacter pylori (H. pylori) es muy prevalente en nuestro medio, y se asocia a enfermedad gástrica muy relevante, tanto benigna como maligna. El patrón oro para su diagnóstico sigue siendo, a día de hoy, la confirmación histológica por biopsia. Sin embargo, cada vez hay más evidencia de que el diagnóstico endoscópico óptico podría tener un papel fundamental que permitiría ahorrar biopsias innecesarias en casos determinados. Concretamente, la distribución regular de las vénulas colectoras (patrón RAC) parece tener un alto valor predictivo negativo (VPN) para descartar dicha infección. En la presente revisión se describen los hallazgos endoscópicos más destacados y con mejor potencial diagnóstico para la infección por H. pylori tras una búsqueda exhaustiva comparando los estudios más relevantes que se han llevado a cabo en Europa y Oriente.
[eng] Helicobacter pylori (H. pylori) infection is highly prevalent in our environment and is associated with highly relevant gastric disease, both benign and malignant. The gold standard for diagnosis is histological confirmation by biopsy. However, there is increasing evidence that optical endoscopic diagnosis could be a fundamental role in avoiding unnecessary biopsies in certain cases. Specifically, the regular distribution of the collecting venules (RAC pattern) seems to have a high negative predictive value (NPV) to rule out infection. This review describes the most outstanding endoscopic findings with the best diagnostic potential for H. pylori infection after an exhaustive search comparing the most relevant studies that have been carried out in Europe and the East.
