  • Title: Transanal endoscopic microsurgery.
    Author: Turner J, Saclarides TJ.
    Journal: Minerva Chir; 2008 Oct; 63(5):401-12. PubMed ID: 18923351.
    Abstract:
    Transanal endoscopic microsurgery, or TEM, is a technique that can be used for the treatment for early staged rectal cancer. This technique utilizes carbon dioxide insufflation through a 40 mm rectoscope to create better endoscopic visualization of the operative field. TEM has been praised for its access to middle and upper-third rectal cancers. However, one limitation of TEM is its inability to address local lymph node involvement. Therefore, an adequate preoperative assessment is crucial before using TEM as a curative modality. TEM can be used to remove virtually any benign lesion that can be brought into view. In addition, there are several studies that have shown TEM is a safe and effective way to treat T1 cancers and may have a role in the treatment of T2 and T3 cancers when combined with radiation and chemotherapy. TEM has lower recurrence rates, faster recovery, and fewer complications when compared to other local excision techniques and radical surgeries. The future of TEM is growing in acceptance as more surgeons learn to master this technique.
