[Results of surgical treatment of colorectal cancers in patients over 70].

276 patients older than 70 years suffering from colorectal cancer underwent surgery during the past 12 years. Several of these patients had additional diseases and often advanced tumour stages. The overall postoperative mortality rate came up to 18%. The results of better preoperative preparation of the bowel by irrigation and antibiotics as well as advanced operative techniques (EEA-stapler) with regard to infection rate, postoperative course and time of hospitalisation are discussed. Extensive follow-up care of treated patient is necessary.
