Objective,2,To observe the effect of acupoint catgut embedding on postoperative recurrence of polyps and metabolic level in patients with colorectal adenomatous polyps （CAP） complicated with metabolic syndrome （MS）.,Methods,2,Eighty patients with CAP （postoperative） complicated with MS were randomly divided into a treatment group （,n,=40） and a control group （,n,=40）. The control group was administered with symptomatic treatment and health management， while the treatment group was administered with acupoint catgut embedding besides the treatment measures of the control group. The treatment lasted 3 consecutive months. The recurrence of polyps in both groups was observed at 6 and 12 months after treatment，and the treatment safety was observed. The levels of serum total cholesterol （TC）， triacylglycerol （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， fasting plasma glucose （FPG）， and glycated hemoglobin （HbA1c）， as well as body mass， body mass index （BMI）， waist circumference （WC）， waist-to-hip ratio （WHR）， systolic blood pressure， and diastolic blood pressure were compared before and after treatment.,Results,2,①During the trial， there were 3 drop-out cases in the treatment group and 2 drop-out cases in the control group. Finally， 75 cases completed the trial， including 37 cases in the treatment group and 38 cases in the control group. ②At 6 months after treatment， there was no statistically significant difference in the postoperative recurrence rate of polyps between the two groups （,P,>,0.05）. At 12 months after treatment， the postoperative recurrence rate of polyps was 13.5% in the treatment group and 34.2% in the control group， and the difference was statistically significant （,P,<,0.05）. ③According to the intra-group comparison before and after treatment， the levels of serum LDL-C， HDL-C， FPG and HbA1c， as well as systolic blood pressure， body mass， BMI， WC and WHR decreased in the treatment group （,P,<,0.05）； The levels of serum TC and LDL-C， as well as WC and WHR decreased in the control group （,P,<,0.05）. After treatment， the levels of serum LDL-C， FPG and HbA1c， as well as systolic blood pressure， body mass， BMI， WC and WHR in the treatment group were lower than those in the control group （,P,<,0.05）. ④No abnormal safety index was found in both groups.,Conclusions,2,Acupoint catgut embedding has certain popularization value as it can prevent the postoperative recurrence of colorectal adenomatous polyps by regulating metabolic levels， and effectively prevent and treat common community diseases such as hypertension， diabetes and hyperlipidemia. The safety of this treatment is good.
