YES
The purpose of this study is to statistically examine the changes in intestinal microbiota and defecation function before and after radical resection of right-sided with resection of the ileal valve and left-sided colon cancer, and to rescue patients suffering from reduced quality of life due to defecation function after surgery.
Others
By examining the specific intestinal microflora that affect defecation function, it is significant to help in the development of optimal probiotics.

1)Defecation function will be evaluated by interview four times before surgery, immediately after surgery, 6 months after surgery, and 12 months after surgery.
2)Defecation function will be evaluated using a questionnaire that combines the CSS, Wexner, and Brillstol stool shape scales, and the total score, individual defecation frequency, stool shape, and other parameters will be considered.
3)The intestinal microbiota will be identified from fecal samples taken three times before surgery, immediately after surgery, and 6 months later, and the distribution, occupancy, and quantity will be comprehensively evaluated. Pre- and postoperative will be statistically analyzed between the two groups as the comparison groups.
Chromosomal DNA of intestinal bacteria will be extracted from feces using Qiagen QiAamp DNA Microbiome Kit.
The 16S rRNA gene sequence of the chromosomal DNA is determined using a next-generation sequencer(Oxford Nanopore).
The intestinal microflora will be clarified by annotation.
Comprehensive evaluation of distribution, occupancy, and quantity, and comparative analysis will be performed.
4)Operative time, blood loss, number of lymph nodes dissected, postoperative complication rate, postoperative hospital stay, pathology, gender, age, BMI, American Society of Anesthesiologists - Physical Status, patient background factors such as history, comorbidities, history of laparotomy, defecation before and after surgery, and probiotic products. The results will also be reviewed with regard to the patient's preoperative and postoperative defecation status, and oral probiotic preparations.
