title: Indications and techniques of transanal endoscopic microsurgery (TEMS).
abstract: Transanal endoscopic microsurgery (TEMS) has recently reemerged as a valuable technique for the management of rectal neoplasms - both benign and malignant. Since the original description of this technique in the early 1980s, TEMS has emerged as the approach of choice for most benign rectal tumors because of the excellent views provided and superior dissection techniques possible when compared to traditional transanal excision. Many published reports demonstrate that the lowest rates of recurrence are associated with TEMS probably because of full-thickness excision with negative margins. Increasingly, TEMS is being applied to primary rectal cancer when used alone as a full-thickness excision alone or in combination with additional therapies, depending on tumor stage. There is now a significant evidence base to suggest that this approach should be considered as part of a multidisciplinary approach to rectal cancer. This paper describes indications and techniques for this technology.
