The ideal operation of rectal cancer excises the disease with minimal
morbidity. The traditional abdominoperineal resection approach to rect
al cancer was considered the surgical gold standard but significant mo
rbidity in the form of mandatory stomas and nonhealing perineal wounds
prompted a search for a better approach, Since about 1940, sphincter-
sparing procedures, such as anterior resection, in appropriately selec
ted patients have achieved equal or greater rates of survival and recu
rrence with the benefit of an improved quality of life, More recently,
transanal local excision and coloanal anastomosis have been used with
increasing frequency to spare the sphincter and cure the cancer.
