Treatment of early rectal tumours by transanal endoscopic microsurgery in Hong Kong: prospective study.

Abstract

Transanal endoscopic microsurgery is a safe procedure and can achieve good local tumour control. It is ideal in the management of rectal villous adenomas at stages pT0 and pTis. Its application is now extended to the treatment of early rectal carcinoma at stage pT1 with curative intent. For tumours at stage pT2 or later, it can also serve as a good option for local palliation.
