[Experimental phantoms for studying diagnostic and therapeutic procedures of the rectosigmoid and upper colon].

The authors represent lifelike exercise models for the training without patient of diagnostic and therapeutic interventions in the rectosigmoid and in the colon. The two models are used for the practical training of the rectosigmoidoscopy with the rigid rectoscope and the coloscopy with the fibre-optical examination technique. In the excorporated animal rectum may be performed polypectomies by means of removal of the loop, exploratory excisions from the intestinal wall as well as electro-surgical and cryosurgical interventions. The experiences got up to now in training classes are described.
