To observe the long-term outcome and postoperative anal function after laparoscopic modified Bacon’s radical resection of rectal cancer.

A retrospective analysis was performed in 63 patients with low rectal cancer from January 2012 to October 2013, who were divided into groups according to surgical methods. Among them, 30 patients receiving modified Bacon’s radical resection of rectal cancer were in group A, and 33 patients receiving laparoscopic double-stapler prerectal resection were in group B. Statistical analysis were performed by using SPSS20.0 software. Measurement data, such as perioperative indicators and nutrition status were expressed as (±s), and were examined by independent test. Count data such as anal function and postoperative complications were examined by chi square test. Cumulative survival were examined by Log-Rank test. A P value <0.05 was considered as statistically significant difference.

There was no significant difference in the amount of blood loss, operation time, number of harvested lymph nodes, defecation ability on 3 months and 12 months after operation, as well as incidence of complication and hospitalization stay between two groups (P>0.05). The postoperative recovery time of intestinal function in group A was shorter than that in group B (P<0.05). The excellent rate of defecation was significantly better than that in group B at 6 months after operation (χ²=4.237, P=0.039). The hospitalization cost was significantly lower than that in group B (t= 8.290, P=0.000). Kaplan-Meier survival analysis showed that the cumulative survival of the two groups were 83.3% and 84.8% respectively (χ²=0.002, P=0.969).

There were no significant difference in complications and survival rate of patients with low rectal cancer undergo laparoscopic modified Bacon’s radical operation of rectal cancer or double stapling technique anterior resection of rectum. However, the improvement of intestinal function recovery and elimination ability of the former after operation is more significantly, which deserves clinical attention.
