Abstract
Radical surgery is considered as the standard treatment for rectal cancer. Transanal
local excision has been considered an interesting alternative for the management of
selected patients with rectal cancers for many decades. Different approaches had been
considered for local excision, from endoscopic submucosal dissection to resections
using platforms, such as transanal endoscopic microsurgery or transanal minimally
invasive surgery. Identifying the ideal candidate for this approach is crucial, as
a local failure after local excision is associated with poor outcomes, even for an
initial early rectal tumor. In this article, the diagnostic tools and criteria to
select patients for local excision, the different modalities used, and the outcomes
are discussed.
