There are a few other descriptions of the frequency of erosive lesions in endoscopy series in Colombian literature. Gomez 41 reported a similar frequency of 5.8% for gastric erosions. In bulletins from the National Day of Digestive Endoscopy in 1999-2002 57, 58 the Colombian Association of Gastrointestinal Endoscopy reported a frequency for gastric erosions of 8.2%. Both are lower than the frequency we report. This can probably be explained by the fact that these were series related to gastric cancer screening in which a large number of participants were asymptomatic or had minor discomfort. In contrast our series included only patients whose dyspeptic discomfort was B enough for their doctors to order a diagnostic study. The frequency of duodenal ulcers that we found Table 4 is higher than the one described by Gomez 41, but lower than that described by Wong.
Existen pocas descripciones en la literatura nacional sobre la frecuencia de las lesiones erosivas en series de endoscopia digestiva como la de Gómez 41 que reporta frecuencia similar y las de la Asociación Colombiana de Endoscopia digestiva en sus boletines del Día Nacional de la Endoscopia Digestiva de los años 1999 y 2002 57, 58, con erosiones gástricas en el 5,8% y 8,2% respectivamente, ambas inferiores a nuestro reporte, explicable probablemente por el hecho de ser series relacionadas con la tamización para cáncer gástrico, en la cual un número grande era asintomático o presentaban molestias leves, en contraposición a nuestra serie, quien fue consultante por sus molestias dispépticas de intensidad suficiente para que su médico solicitase el estudio diagnóstico.
