Transanal endoscopic microsurgery (TEM) is a technique which offers exceptionally good visualization combined with the ability to precisely excise lesions throughout the rectum. One of the greatest advantages of TEM excision is that even large lesions can be removed intact and both deep and radial margins can be assessed. TEM requires careful preoperative preparation in order to avoid complications and maximize patient benefits.


Informed consent for TEM should include a discussion about the nature of the procedure and its potential risks and complications. These include, but are not limited to, incontinence, bleeding, perforation, rectovaginal fistula, incomplete resection, and inability to resect the lesion. Our approach has been to inform patients the TEM equipment provides us with the ability to do an excisional or “superbiopsy” of the lesion. It should be made clear to the patients that this may be only the first step in the diagnosis of their problem and they may require...
