Transanal endoscopic microsurgery (TEM) has been used since the 1980's for the treatment of selected rectal cancers, with clear benefits regarding morbidity and mortality, and good oncological outcomes when compared to radical surgery and conventional local resections. The high cost of equipment and the need for long learning curve did not allow the spread of the technique. The aim of this study was to describe the technical characteristics and outcomes of 4 patients operated by this technique, 3 with histologically confirmed adenomas and 1 carcinoid rectal tumor, with no recurrence after an average -follow-up of 12 months. The use of single port devices for transanal surgery is a safe method with good oncological results and allows a faster learning curve, by the similarity with conventional laparoscopic procedures and the availability of devices commonly used in laparoscopy.
