[Personal experiments in treating rectal rumors with the TEM technique].

Transanal Endoscopic Microsurgery (TEM) was introduced to clinical practice by Buess in 1983. After several years of gaining experience technique has been used for the excisions of rectal tumours. TEM enables excisions of the tumours localised in the rectum and distal portion of the sigmoid colon from 5 to 25 cm from the anal verge. Until now 13 patients have been operated using TEM method. The group includes also rectal cancers classified as pT-1 and G-1. Preliminary results are encouraging. The patients left the hospital four days after the procedure and started professional activity two weeks postoperatively. All the patients are followed-up: patients who had adenomas once a year and those with pT-1 low-risk rectal cancer-every three months in their first postoperative year and then in six month intervals. Local excision of the adenomas and early cancers of the rectum with the use of TEM proves to be an effective method of surgical treatment in a selected group of patients.
