Summary
Seventy-five patients with sessile adenomas or early carcinomas of the rectum or rectosigmoid
were operated on with the new technique “transanal endoscopic microsurgery” Employing
a newly developed complex endoscopic operating system, complete removal of sessile
adenomas can be accomplished up to a distance of 25 cm from the anal verge, accurately
and non-invasively. Complications occurred in three cases, with no resulting mortality.
In the follow-up period we discovered only one adenomatous recurrence that required
operative treatment. The superior accuracy of preparation, a short average stay in
hospital, and low recurrence and complication rates are the advantages of this transanal
endoscopic operative technique.
