[First results of transanal endoscopic surgery (sec. Buess) in Hungary]

The operative technic, the instrumentation, the indication field and the first domestic results of the transanal endoscopic microsurgery (TEM) is presented. The method is suitable to the removal of the benign and the well or intermediately differentiated T1-2N0M0 stage low risk carcinomas taking place under the reflection of the pelvic peritoneum. The procedure is equally favourable comparing to the previously applied operative methods in respect of the oncological criteria, the anal sphincter preservation and the operative risk. The median tumour surface of the 17 (12 benign, 5 malignant) rectum tumours operated on till the March 1996 was between 9.2 and 16.7 cm2. The level of the tumours from the dentate line was between 3 and 13 cm, the greatest tumour diameter was about 7 cm. During the 14.1 month long median follow up period only one local recurrence of a T1N0M0 carcinoma has been observed and was reoperated with the TEM technic again. The TEM method seems to solve the problem of the oncologically reliable, anal sphincter saving, proportional to the severity of the illness operation of the benign and small malignant tumours in the middle and lower part of the rectum.
