Abstract. Progress in surgical technologies enables us to perform minimally invasive organ sparing procedures in cases of early diagnosis of cancer. The aim of the study was to improve the results of surgical treatment of patients with early stages of rectal cancer. The study enrolled 120 patients with rectal cancer. 40 patients were treated by transanal endoscopic microsurgery, 40 patient ― by endoscopic mucosal resection; 40 patients had conventional radical surgery. Short- and longterm results were studied. Lower morbidity rate (10%), satisfactory level of quality of life, economical advantages were observed in organ sparing surgery patients. However, local recurrence rate (10%) after TEM in patients, who could be cured by performing TME, was too high. The strategy for managing rectal cancer patient, who is the candidate for organ sparing surgery, was developed.

Key words: rectal cancer, transanal endoscopic microsurgery, endoscopic mucosal resection, local excision.
