To investigate the distribution of traditional Chinese medicine (TCM) constitution，and to identify the type of constitution by the epidemiological investigation of TCM constitution in patients with colorectal tubular adenomas. Methods:A total of 449 patients with colorectal tubular adenomas admitted to the First Affiliated Hospital of Harbin Medical University from June 2016 to July 2017 were randomly selected to complete the TCM constitution questionnaire. The clinical data of the surveyed individuals were also collected to analyze the distribution of TCM constitution in patients with colorectal tubular adenoma. Results:In the patients with colorectal tubular adenoma，the incidence rate of males was significantly higher than that of females，and the peak age of tubular adenomas was 51-60 years old，accounting for 36.75%. There was no significant difference in the age of male and female colorectal tubular adenoma (P>0.05). The yang deficiency constitution is a type of constitutional susceptibility in patients with colorectal tubular adenomas，followed by damp-heat and phlegm-dampness constitution. The distribution of yang deficiency in the subjects of different ages was statistically significant. There was a statistically significant difference in constitutions of damp-heat，phlegm-dampness，blood-stasis and speciality between different genders (P<0.05). There was statistical significance in constitutions of qi deficiency，yin deficiency，damp-heat and qi-stagnation among smoking and non-smoking patients with colorectal tubular adenoma . Conclusion:People with constitutions of yang deficiency，damp-heat，phlegm-dampness are more susceptible to have colorectal tubular adenoma.
