BACKGROUND: According to the indexes of serum and anal function, acupuncture therapy was applied to patients with low rectal cancer in order to avoid the occurrence of anal incontinence and reduce complications. AIM: To explore the clinical application and evaluate the effect of acupuncture therapy for anal function rehabilitation after low-tension rectal cancer surgery. METHODS: From the anorectal surgery cases, we selected 120 patients who underwent colorectal cancer surgery between January 2020 and December 2022 and randomly divided them into a control group (n = 60), observation group (n = 60), and control group after surgery for lifestyle intervention (including smoking cessation and exercise), dietary factor adjustment, anal movement, and oral loperamide treatment. The serum levels of motilin, 5-hydroxytryptamine, and vasoactive intestinal peptide (VIP), Wexner score for anal incontinence, and incidence of complications were compared between groups. RESULTS: After treatment, the VIP and 5-hydroxytryptamine levels in the observation group were lower than those in the control group (p < 0.05). The motilin level was higher than that in the control group (p < 0.05). Postoperative anal incontinence was better in the observation group than in the control group (p < 0.05). The incidence of complications in the observation group was 6.67%, which was significantly lower than that in the control group (21.67%; p < 0.05). CONCLUSION: Acupuncture therapy has a positive effect on the rehabilitation of anal function after low-tension rectal cancer surgery; it can effectively help to improve the serum indices of patients, avoid the occurrence of anal incontinence, and reduce the incidence of complications. Popularizing and applying it will be valuable.
