Transanal endoscopic microsurgery (TEM) was developed by Gerhard Buess and associates in Germany and was made available in 1983 for clinical use [1]. TEM and its instrumentation provide superior optics and excellent exposure to allow removal of favorable tumors from the rectum and the rectosigmoid colon up to 24 cm from the anal verge. It is the only one-port system in endoscopic surgery that utilizes a direct endoluminal approach to a target organ via a natural opening of the body [2]. TEM offers an alternative to conventional transanal surgery, which is limited by its use of conventional instruments and radical surgery and which is associated with a much higher complication rate.

Since its inception there has been an extensive global experience with TEM which substantiates its effectiveness and associated low morbidity rate [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]. TEM avoids the high complication rates associated with radical surgery, namely, anterior resection and...
