Recurrence is 20% if it affects the safety border, and 50% if there are malignant cells on the other side of the safety border. Besides this, it must be remembered that in the different series the risk of metastatic lesions in mucosal lesions is between 1% and 3%. In some series the risk rises to 5%, and in submucosal lesions it is between 15 to 25%.
Además recordemos que en las diferentes series, el riesgo de lesiones metastásicas en lesiones mucosas es del 1 al 3% e incluso en algunas series hasta del 5% y en lesiones submucosas del 15 al 25%, lo que obliga a realizar un estricto seguimiento clínico, endoscópico, histológico y radiológico.
