The endoscopy was considered to be negative if erythema, hyperemia and7or non-erosive inflammatory signs were found. Patients were considered to have different types of functional dyspepsia according to the predominant symptoms: dyspepsia due to ulcer if pain was the predominant symptom, dysmotility-like dyspepsia if distention or gastric fullness were the predominant symptoms, or non-specific dyspepsia if it was not possible to establish a predominant symptom according to ROMA II 11-14.
La presencia de eritema, hiperemia y signos inflamatorios no erosivos llevaron a la interpretación del estudio endoscópico como negativo y por lo tanto los pacientes fueron considerados con dispepsia funcional clasificándolos de acuerdo al síntoma predominante en dispepsia tipo ulceroso, si el dolor era el síntoma predominante; en dispepsia tipo dismotilidad, si el síntoma predominante era la distensión o la plenitud epigástricas; o en dispepsia inespecífica si no se lograba establecer síntoma predominante de acuerdo a ROMA II 11-14.
