Colorectal cancer is a common pathology, causing approximately 861,000 deaths a year. The case a 50-year-old male patient, with arterial hypertension and type II diabetes mellitus, with a diagnosis of neoplasia in the descending colon, which was performed minimally invasive procedure, after tumor marking with methylene blue by means of endoscopy of lower digestive tracts. Adequate postoperative period, without complications. The treatment of choice for colorectal cancer without metastasis is oncological exeresis. Currently the recommended surgical management is by means of a minimally invasive procedure, however, it is a challenge since in some cases the identification of the lesion is difficult and additionally requires a pronounced learning curve. Therefore, we use methylene blue for the marking of the tumor after the procedure, with excellent results, without complications. Methylene blue tumor marking prior to the minimally invasive procedure is safe, useful, inexpensive, and low risk.
