Investigation on complementarity between total mesorectal excision and radical resection in relation to postoperative local recurrence in patients receiving anus-reserve operation on rectal cancer

Objective:To investigate the difference and complementarity between total mesorectal excision(TME)and radical resection in relation to postoperative local recurrence in patients receiving anus-reserve operation on rectal cancer.Methods:Clinical data of 81 cases during a period from 1975 to 2001 were retrospectively analyzed.Results:In the 81 cases with local recurrence,49 of them laid to anastomosis and mesorectum,17 lymph nodes and 15 multi-site relapse.The choice of operative procedure included abdominoperineal resection in 58 cases,Hartmann’s operation in 4 cases,simple double-pelvic stoma in 12 cases,exploration in 7 cases,and total pelvic or rear-pelvic resection in combination with other organs in 6 cases. The rate of resection was 84.0%(68/81).32 cases reached clinical radical degree,and the rate of radical resection was 39.5% (32/81).The 5-year survival rate was 34.4%(11/32).Conclusion:Based on actual condition of the patients,attention to radi- cal resection and total mesorectal excision are necessary,and reasonable adoption of the operative procedure could reduce the local recurrence of rectal cancer.
