Objectives
Narrative objectives1	After colorectal surgery, SSI (surgical site infection) occurs at higher frequency than other gastroenterological surgery, and degrades patients QOL. It has been reported that probiotics has beneficial effect on immunity and bacteriostasis to H. Pylori, E. Coli and P. aeruginosa. There are some reports showing probiotics reduced the infection rate after cholangiocarcinoma surgery. However, there has been no report about colorectal cancer. This strategy is cheap and easy to perform. The number of colorectal surgery will increase in the future, therefore, we believe that this study will greatly contribute to surgical practice.
