[Minimally invasive surgery of the colon and rectum].

In the period from 1.8.89 to 1.7.92 140 adenomas and 63 carcinomas were locally resected from the rectosigmoid area with the instruments of TEM. The mortality was 0.5%, the rate of dehiscence of the suture 9.8%. 75% of these were treated conservatively. One of the 29 patients with locally resected pTl-low risk-carcinoma developed a recurrence so far. The rate of recurrent adenomas was 1.4%. From 7.1.1992 to 24.5.1993 21 procedures in colorectal surgery were performed laparoscopically or in a combined laparoscopic transanal operation. The mortality was zero. 1 case of suture dehiscence, 2 cases of crural phlebothrombosis and 1 lesion of the left ureter were observed. The use of TEM in the combined procedure means an extension of the range of minimally invasive colorectal surgery to the lower rectum.
