Transanal endoscopic microsurgery (TEM) was introduced in 1983 as an
alternative to radical proctectomy for the management of rectal adenomas
unsuitable for endoscopic or standard transanal resection. Since, its
indications have progressively broadened to early rectal cancer. This review
article will assess the role of TEM for T1 rectal cancer management, along
with its operative and long-term results.
