  • Look Inside

The technique and indications of transanal endoscopic microsurgery (TEM) using an operating recto-scope with a diameter of 4 cm are described. The rectoscope can reach the rectum up to 20cm from the anal verge. Sessile adenomas with a diameter of 2.5cm or larger, sessile in-situ carcinomas with a diameter of 1.5cm or larger, and well differentiated carcinoid tumors with a diameter of 1.5cm or less are indication for TEM. With TEM technique large en block resection with enough safety margins can be performed by using a needle-shaped high-frequency knife.
