Abstract
Objective To explore the changes and factors of anus preservation rate in anus-protection operation on low rectal cancer in different periods. Methods 79 cases during July 2003 to June 2008 were classified as the long-term group,while 104 cases during July 2008 to June 2013 were classified as the short-term group,the patients in the short-term group were treated with the total mesorectal excision.All patients were divided into 45 cases of group ARP and 138 cases of group SP according to whether or not undergo anus preserving operation. Results The difference was statistically significant between the early group and late group(P < 0.05). SP comparison of two groups,the difference was statistically significant(P < 0.05). APR group of the inferior margin of the tumor distance from the anal verge was smaller than that of SP group, the anal preservation rate in less than 1/2 tumor diameter,1/2-3/4 tumor diameter,>3/4 tumor diameter and total tumor diameter decreased by turns(P<0.05),and that in mass type,ulcer type and infiltration type of tumor gross type and in high,medium, low differentiated carcinoma and in Dukes A,B,C,D phase of low rectal cancer also decreased by turns(P < 0.05). Conclusion Total mesorectal excision improves the anus preservation rate of low rectal cancer at some extent.Tumor diameter, tumor staging,tumor location,tumor body gross type,tumor differentiation and sex of the patients and BMI can affect the anus-protection operation in low rectal cancer.关键词
