Abstract
Transanal endoscopic microsurgery (TEM) has emerged as a minimally invasive means of resecting rectal tumors. Developed in Germany and now being used with increasing frequency in the United States, TEM utilizes a 40-mm operating rectoscope, which is sealed with an airtight facepiece. Carbon dioxide is constantly infused, thereby distending the rectum and maintaining visibility. A variety of instruments, such as tissue graspers, a high-frequency knife, suction, and needle holders, are inserted through the facepiece. Adenomas that are small, large, or even circumferential, as well as selected carcinomas up to 24 cm, can be removed with TEM instrumentation. The optics provide sixfold magnification, and this, combined with the constantly distended operative field, allows for a precise excision of the tumor as well as closure of the wound. For lesions in the mid and upper rectum, TEM is an alternative to a transsacral or transabdominal approach, with subsequently shorter hospital stay and fewer complications.Keywords
