[TEO: minimally invasive surgery of the rectum. A short review].

The equipment and technique of transanal endoscopic microsurgery was developed by Buess in the early 80s. The technique was more refined, and the indication was widened since then. Excellent oncological results can be achieved with good patient selection with this less invasive technique and the complication rate is very low in contrast to conventional techniques. Nowadays the transanal endoscopic microsurgery is the "gold standard" in the treatment of benign lesions and low risk T1 cancer of the rectum.
