ABSTRACT
Objective:To investigate the risk factors of adenomatous colorectal polyps in advanced stage.Methods:Retrospective cross-sectional study. A total of 400 hospitalized patients with colorectal polypectomy and pathological diagnosis of adenomatous polyps (Aps) were selected from December 2020 to December 2022 in Shenzhen Hospital of Beijing University of Chinese Medicine (Longgang), of which 107 patients with progressive adenomas and 293 patients with common adenomas were selected. General information of patients (name, gender, age, BMI), history of smoking, alcohol consumption, history of hypertension, history of diabetes mellitus, and results of 13C urea breath test were collected to analyze the risk factors for the development of adenomas in patients with progressive adenomas and their syndromic characteristics. Results:The distribution of male patients with advanced adenoma was significantly higher than that of common adenoma patients [70.09% (75/107) vs. 57.34% (168/293), P=0.021], and the ages were [(52.25±9.81) years vs. (48.41±10.23) years, P=0.001], BMI [(24.37±3.19) kg/m 2vs. (23.38±3.25) kg/m 2, P=0.007] significantly higher than those of ordinary adenoma patients. Intestinal damp-heat syndrome was the common witness type in both advanced and common adenomas, and the distribution of intestinal damp-heat syndrome in advanced adenomas was significantly higher than that in common adenomas [43.0% (46/107) vs. 32.1% (94/293); χ2=4.10, P=0.043]. The distribution of patients with alcohol drinking history in advanced adenomas was significantly higher than that in common adenomas [61.7% (66/107) vs. 39.3% (115/293); χ2=15.92, P<0.001]. The distribution of diabetic patients with advanced adenoma was significantly higher than that of common adenoma patients [29.9% (32/107) vs. 14.7% (43/293); χ2=19.94, P<0.001]. The infection rate of Hp in advanced adenoma patients was significantly higher than that in common adenoma patients [66.4% (71/107) vs. 44.7% (131/293); χ2=14.69, P<0.001]. Logistic regression analysis showed that age, BMI, male, intestinal damp-heat syndrome, drinking history, diabetes history and Hp infection were risk factors for the development of patients with progressive adenomas ( P<0.05 or P<0.01). Conclusion:Intestinal damp-heat syndrome is the key syndrome in patients with progressive adenoma, and age, BMI, male, history of alcohol consumption, history of diabetes mellitus and Hp infection are the risk factors for its development.
