ABSTRACT

Introduction: Endoscopic treatment is currently considered the first choice for early digestive cancer without lymph node metastasis.
Objective: To describe the usefulness of endoscopic mucosal resection and endoscopic submucosal dissection in patients with in situ pre-malignant lesions and colon and rectal cancer.
Methods: A descriptive, prospective study was carried out in a series of cases of the National Minimum Access Surgery Center, from January 2015 to July 2016.
Results: The series consisted of 20 patients with a mean age of 64.2 years. There was a predominance of females (70%), 28 lesions were excised, mostly endoscopic mucosal resection was used. The block resection rate reached was 75%. The rate of radical resections with injury-free margins reached was 71.4%. The histological classification of Vienna was used for intraepithelial neoplasms. There were no complications related to the techniques used.
Conclusions: Endoscopic mucosal resection and submucosal dissection techniques were useful in the treatment of patients with pre-malignant lesions and in situ colon and rectal cancer.
