Abstract

Abstract:

Transanal endoscopic microsurgery(TEM)is a new surgical method which combines the advantages of anal approach, rectal endoscopic technology, laparoscopic technology and minimally invasive technology. This surgical method can enlarge the operative field of vision by six times, make the operator more clear and accurate resection of upper and middle rectal lesions, overcome the limitations of resection of anal sphincter and pelvic bone boundary, and is suitable for rectal adenoma, rectal polyp, etc. TEM is suitable for cT1 rectal cancer without lymph node metastasis, but there is still some controversy about the treatment of higher grade rectal cancer. Neoadjuvant radiotherapy and chemotherapy combined with TEM in the treatment of rectal cancer is being actively carried out at home and abroad, and good results have been achieved. This paper reviews the surgical instruments, methods, indications, preoperative evaluation, latest progress and controversy of TEM.

Key words: Transanal endoscopic microsurgery, Rectal cancer, Prospects
