Objective To explore the distribution characteristics of traditional Chinese medicine（TCM） syndrome types and TCM constitution of patients with colorectal polyps. Methods Totally 160 patients diagnosed as colorectal polyps through colonoscopy and pathological examination were included. The general conditions（gender

age

eating habits and bad habits

etc.）

clinical symptoms

and the information from TCM four examinations were collected; TCM constitution was assessed. TCM symptoms

syndromes and constitutions were analyzed according to different pathological types of polyps（adenomatous polyps and non-adenomatous polyps）. Logistic regression analysis was used to screen out the independent risk factors for the incidence of colorectal polyps. Results There were 159 out of 160 patients were ≥45 years old

and abdominal pain was mainly manifested（145

90.63%）. The most commonly seen TCM syndrome was liver constraint and spleen deficiency syndrome（87

54.38%）

followed by large intestine damp-heat syndrome（26

16.25%） and liver constraint and qi stagnation syndrome（19

11.88%）. Qi deficiency（111

32.27%）

qi constraint（88

25.58%） and damp-heat（41

11.92%） were top three TCM constitution types. There were 108 patients with adenomatous polyps and 52 with non-adenomatous polyps. The distribution of TCM syndromes and TCM constitutions between two pathological polyps were significantly different（P<0.01）. For adenomatous polyps

liver constraint and spleen deficiency syndrome was the most commonly seen type

as well as qi deficiency and qi constraint constitution type; for non-adenomatous polyps

large intestine damp-heat syndrome had the highest frequency

and the damp-heat and blood stasis were main TCM constitution types（P<0.05 or P<0.01）. Conclusion The main syndromes of patients with colorectal polyps are liver constraint and spleen deficiency syndrome

large intestine damp-heat syndrome

and liver constraint and qi stagnation syndrome

and the constitution types are mainly qi deficiency

qi stagnation and damp-heat. The pathological conditions of colorectal polyps patients with different TCM constitutions and TCM syndromes are different.
