Abstract:
The purpose of the study: is to determine the indications and contraindications for sphincter-preserving surgeries
in lower rectal cancer. Material and methods: In the Coloproctology Department of the Republican Cancer
Research Center (RCRC) for the period 2011-2015, 1,346 patients with a verified diagnosis of colorectal cancer
(CRC) received inpatient treatment. Based on the results, the following therapeutic measures were performed
before the operation. At the same time, in contrast to the previously proposed methods of preoperative therapy, we
carried out complex therapy, including neoadjuvant endolymphalum chemotherapy and intensive
hypoxeradiotherapy. Among 1346 patients, 496 patients with T2-3N0-1M0 stage of the process performed radical
operations. Cancer of the lower ampoule was in 142 (28.6%). Among 142 (28.6%) patients, 64 (45.1%) performed
sphincter-preserving operations named abdominal-anal resection of the rectum (AARR), the average age of the
patients was 59.8 years, in 78 (54.9%) patients abdomino-perineal extirpation of the rectum (APER) was
performed, during which the entire switching apparatus of the rectum is removed - the average age of 54.2 years.
