Statistically significant value. (1) Anastomotic complication refers to anastomotic leakage, bleeding, or stenosis after operation in this study. (2) Postoperative fever was defined as a body temperature ≥38.5°C within seven days after operation. (3) Total recurrence refers to patients with local recurrence and/or distant metastasis during follow-up after operation.
