Abstract
In Reply We thank Hu and Sun and Zhu et al for their comments on our article.1 We agree with Hu and Sun that the differentiation of tumors and incision length may affect the occurrence of postoperative infectious complications. In this study, all the participating centers were tertiary teaching hospitals, and the standardized procedures for surgical operations were implemented uniformly. After randomization, there were no differences in disease types and surgical options between the 2 groups, and deviations due to tumor differentiation and incision length could be reduced as much as possible. These are indeed limitations of this study, which need to be further explored in the future. In our study, patients followed standard protocols according to the Enhanced Recovery After Surgery (ERAS) concept. ERAS guidelines do not recommend mechanical bowel preparation with systemic antibiotic prophylaxis to be used routinely in colonic surgery because there is no clinical advantage.2 Therefore, we did not perform routine mechanical bowel preparation.
