In our environment nonpolypoid neoplastic lesions appear at rates similar to those in series published in the literature. This motivates us to take extreme measures to recognize them. The emphasis should be on complete colonoscopies and ensuring optimal colon preparation. Furthermore, we assert that the treatment of these injuries by endoscopic mucosal resection is safe and effective for the eradication of these lesions. 1. Muto T, Kamiya J, Sawada T, et al.

Las lesiones neoplásicas no polipoides en nuestro medio se observan en porcentajes similares a los de series publicadas en la literatura, esto nos motiva a extremar las medidas para su reconocimiento, haciendo énfasis en la realización de colonoscopias completas y garantizando una óptima preparación de colon.
