Transanal endoscopic microsurgery combined with endoscopic posterior mesorectum resection in the treatment of patients with T1 rectal cancer – 3-year results

摘要

IntroductionRectum-sparing transanal endoscopic microsurgery (TEM) is a well-established treatment for T1 rectal cancer (RC). However, it is associated with an increased rate of local recurrence in comparison with extended resection. In most cases this failure is linked to inappropriate case selection and the presence of clinically non-detectable metastases in the regional lymph nodes. Endoscopic posterior mesorectal resection (EPMR) makes it possible to remove the relevant lymphatic drainage of the lower third of the rectum in a minimally invasive way, which in turn can help in adequate tumor staging.
