Abstract
Objective To explore the curative ef ects of anal sphincter preserving operation for low rectal carcinoma. Methods:48 cases of low rectal carcinoma between 4~7 cm from anal verge were underwent anal sphincter preserving operation using double stap ling device (ASPO group),2 of them were multiple synchronous cancer and 6 patients have acute colon obstruction;60 cases of rectal carcinoma between 2~7 cm from anal verge were underwent Miles operation (Miles group). Analysis was conducted on three-year survival rate, local recurrence rate, defecation function and fecal control function between the two groups. Results:The local recurrence rate of ASPO group and Miles group was 8. 33%and 8.33%respectively, the three-year survival rate of the two groups was 87.5%and 88.3%respectively,and there was no significant dif erence between the two groups(P>0.05). Defecation frequency of the two group swas reduced after one year, and no statistical dif erence (P>0.05). The fecal control function for ASPO group improved obviously after 12 months,and no complete fecal incontinence occur. But Miles group has not fecal control function. ASPO group provides bet er postoperative fecal control function than Miles group (P<0. 05). Conclusion:Anal sphincter preserving operation for rectal cancer between 4~7 cm from anal verge can be done on patients.Anal preservative operation provides the same curative ef ect as Miles operation does in a short term fol ow-up, and it can achieve bet er postoperative function than Miles operation in fecal control function. Multiple synchronous cancer and colon obstruction are not the surgical contraindication.关键词
