| Popis: | Background Abdominoperineal excision of the rectum with a permanent end-sigmoid colostomy was the classical operation for cancer of the distal third of the rectum. A number of factors have recently led to a more conservative approach, allowing sphincter preservation when excising tumours that are not invading the anal sphincter. Methods The review is based on the published literature of the treatment of low rectal cancers accessed by searching Medline and other online databases. It includes a description of all the surgical options currently available for low rectal tumours, and a discussion of the advantages and disadvantages of the types of anastomosis and reconstruction. Results and conclusion It is now technically possible to remove rectal cancer that is extending into the anal canal with preservation of the anal sphincter mechanism and with a satisfactory oncological outcome. Ultra-low colorectal and coloanal anastomosis, together with a colonic pouch or coloplasty, produces acceptable function in many patients. However, there is still controversy about the risk of tumour implantation, the place of downsizing neoadjuvant therapy, and true long-term functional outcome. Despite these concerns, surgeons should strive to perform rectal resection with sphincter preservation for low-lying rectal cancer whenever possible. |
