Abstract: 【Abstract】 Objective〓To compare the the therapeutical effect between laparoscopic assisted Dixon and Miles radical resection for low rectal cancer. Methods〓Eighty-three patients with low rectal cancer who received laparoscopic assisted surgery were included in the study according to the inclusion and exclusion criteria from January 2008 to December 2010..The enrolled patients were divided into two groups: Dixon group (41 cases) and Miles group (42 cases). The clinicopathological data, surgical quality, postoperative survival and recurrence data were compared between two groups. Results〓There were no distribution differences in clinical data between Dixon group and Miles group. The mean operative time and intraoperative blood loss in Dixon group were shorter than that in Miles group (P<0.05), however the Miles group cost less postoperatively. No differences were found between two groups in the numbers of lymph nodes harvested postoperatively and positive lymph nodes. Both two groups had similar bowel function recover time..The overall postoperative complication rate in Dixon group was 17.0% and 21.4% in the Miles group(P>0.05)..The postoperative 5-years overall survival rate of Dixon and Miles group was 60.6% and 56.2% respectively and no survival difference was found between them..During follow-up period,.the recurrence rates between Dixon and Miles groups were similar(12.2% vs 11.9%,.P>0.05)...Conclusions〓Laparoscopic assisted Dixon radical opera-tion for low rectal cancer was a safe surgical procedure and had similar clinical effect with laparoscopic assisted Miles rectal surgery..The long-term survival outcome of laparoscopic assisted Dixon surgery was similar to laparoscopic assisted Miles surgery.
