Abstract

The transanal endoscopic microsurgery (TEM) technique, first described by Buess nearly three decades ago (Buess et al., Chirurg 55(10):677–680, 1984), has been increasingly adopted by colorectal and minimally invasive surgeons, who are progressively incorporating this minimally invasive approach into their practice. There are currently two main platforms for performing TEM: The Richard Wolf system (Richard Wolf GmbH, Knittlingen, Germany) and the Karl Storz (KARL STORZ GmbH, Tuttlingen, Germany) transanal endoscopic operation (TEO) system. These systems were developed prior to the mainstream adaptation of laparoscopy into general surgery, in order to facilitate exposure and resection of mid and upper rectal lesions not amenable to routine transrectal techniques. Over time, modifications of the equipment have been introduced to incorporate some of the devices and lessons learned from laparoscopic surgery. This chapter will review the technique of transanal endoscopic microsurgery in detail. Additionally, indications, patient preparation, and equipment setup will be briefly reviewed.
