Other related information

Fecal samples are collected on the day before or the day of surgery in all eligible patients who have given consent to provide a stool sample. Postoperative pain is scored on an 11-point scale from 0 to 10 using the NRS, with three scores: 24 hours postoperatively, maximum postoperative pain and pain during movement. With a higher NRS group as the high pain group and a lower NRS group as the low pain group, and gut microbiota analysis is performed from preoperative stool samples. The gut microbiota is analysed by rRNA and metabolite analysis.
