Principles and Techniques

Transanal endoscopic microsurgery (TEM) was developed in the early 1980s in Tu¨ bingen, Germany, by Gerhard Buess and the Richard Wolf Medical Instrument Company to remove large rectal polyps beyond the reach of standard transanal excision. It has blossomed into a valuable, state-of-the-art technology equal to any other technique in terms of reliably positive patient outcome.
