Transanal endoscopic microsurgery is a technique for resection of some focal T1 stage rectal cancers.
Features of a rectal cancer that may make it a candidate for this approach
- well- or moderately-differentiated tumors that are T1 N0 M0 (confined to submucosa without spread)
- <3 cm
- within 8 cm of the anal verge
- involve less than 30% of the wall circumference
