dc.description.abstractEl Diagnóstico temprano del la patología tumoral de colon se ha realizado de manera tradicional con colonoscopia directa, sin embargo existen varios métodos tradicionales que también contribuyen en este diagnostico como el test de sangre oculta en heces, el colon por enema simple o con doble contraste (4,5). Con el desarrollo de las nuevas técnicas diagnosticas surge la colonoscopia virtual como un nuevo método realizado en un tomógrafo de múltiples cortes, a partir del cual se obtienen imágenes del colon en segunda y tercera dimensión para una evaluación de todos lo segmentos del colon, incluso aquellos que no pueden ser vistos en la colonoscopia convencional. Esta colonoscopia ha reportado en diferentes estudios sensibilidad mayor al 90 % para lesiones adenomatosas mayores a 10 mm de diámetro, sin embargo para lesiones que miden entre 6 y 9 mm de diámetro la sensibilidad y especificidad disminuyen (6). Es un nuevo método diagnostico mínimamente invasivo que representa poco riesgo para el paciente, tiene varias ventajas como el corto tiempo requerido para la realización del examen, no requiere sedación, permite valorar todos los segmentos del colon a pesar de áreas de estenosis distales, ayuda a localizar las lesiones con exactitud y permite estadificar los carcinomas, además permite valorar los demás órganos intrabdominales.spa

dc.description.abstractenglishThe early diagnosis of colon tumor pathology has been carried out in a traditional way with direct colonoscopy, however there are several traditional methods that also contribute to this diagnosis, such as the fecal occult blood test, the colon by simple or double contrast enema ( 4.5). With the development of new diagnostic techniques, virtual colonoscopy arises as a new method performed in a multiple-slice tomograph, from which second and third-dimensional images of the colon are obtained for an evaluation of all colon segments, even those that cannot be seen in conventional colonoscopy. This colonoscopy has reported in different studies a sensitivity greater than 90% for adenomatous lesions greater than 10 mm in diameter, however, for lesions measuring between 6 and 9 mm in diameter, the sensitivity and specificity decrease (6). It is a new minimally invasive diagnostic method that represents little risk for the patient, it has several advantages such as the short time required for the examination, it does not require sedation, it allows to assess all the segments of the colon despite areas of distal stenosis, it helps to locating the lesions with precision and allows staging the carcinomas, in addition to assessing the other intra-abdominal organs.eng
