Objective:To explore the application value of Chinese medicine in enhanced recovery after surgery (CMERAS) for rectal cancer surgery. MethodsNinety patients with rectal cancer were randomly divided into treatment group and control group with 45 cases in each group. The control group adopted enhanced recovery after surgery (ERAS) for perioperative management, while the treatment group adopted CMERAS for perioperative management. The changes of TCM syndromes of the two groups were observed by using “TCM online" visual diagnostic instrument during the treatment process, and the clean degree of intestines during the operation, the first time of anal exhaust after the operation, the hospitalization time after the operation, the direct medical expenses and the occurrence of complications were compared between the two groups.  Results: ①=1\*GB3Before treatment and on the first day after operation, there was no significant difference in the number of spleen deficiency syndrome cases, yin deficiency syndrome cases, qi deficiency syndrome cases, phlegm dampness syndrome cases and non-syndrome cases identified by visual diagnostic instrument between two groups (P>0.05). On the day of discharge, the number of patients with spleen deficiency syndrome, yin deficiency syndrome, qi deficiency syndrome and phlegm-dampness syndrome in the treatment group was less than that in the control group (P<0.05), and the number of non-syndrome cases was more than that in the control group (P<0.05). ②Intraoperative clean degree of intestines in the treatment group was better than that in the control group (P<0.05), the first time of anal exhaust after operation was earlier in the treatment group than that in the control group (P<0.05), the postoperative hospitalization time was shorter in the treatment group than that in the control group (P<0.05), and the direct medical expenses in the treatment group were less than that in the control group (P<0.05).③The incidence of complications in the treatment group and the control group were 4.4% and 2.2% respectively, with no significant difference (P>0.05).  Conclusion:Compared with ERAS, CMERAS is beneficial to improve the pathological states of spleen deficiency, qi deficiency, phlegm-dampness and yin deficiency of rectal cancer patients after operation, accelerate postoperative rehabilitation, shorten hospitalization time and reduce medical expenses.
