[Conservative operations in malignant tumors of the rectum and the sigmoid colon].
The results of treatment in 230 patients with malignant transformation of polyps and villous tumors, carcinoid and cancer of the rectum and sigmoid are reported. The aforementioned tumors were removed by transanal excision, electrocoagulation adn posterior proctotomy. In 33 patients economic operations for rectal cancer were associated with radiotherapy. Late results indicated that after economic resections for rectal cancer in most cases a persistant cure is gained. In malignified polyps, villous tumors and rectal carcinoids electroexcision or electrocoagulation seems to be an adequate procedure. Patients subjected to economic resections need to be examined every month during the first postoperative year, and later once in six months.
