The local recurrence rate of rectal cancer is high, the incidence rate is about 8.8%, and the survival rate of patients with rectal cancer after radical resection is 20%-40%. Local recurrence can be divided into 3 types, were limited to board type, infiltration type and lateral infiltration of sacrum. An anastomotic recurrence belongs to limited type, reoperation rate is high, and infiltrative type and infiltrative type of lateral sacral resection is difficult. The prognosis of local recurrence three types are different, the foreign reports of localized 5 year survival rate was 40.9%; 11.4% sacral infiltration; lateral infiltration type 5 year survival rate was zero. The current view that the implementation of expanding operation on patients with type sacral infiltration (such as total pelvic exenteration etc.) should be careful, because of the low quality of life of patients after operation.
