Abstract:
Objective:To analyze the Helicobacter pylori ( Hp) infection status in patients with colorectal polyp, and to study the relationship between the clinical features of colonoscopy and the Hp infection. Methods:The clinical data of 637 patients underwent colonoscopy from January to December 2022 in Dalian Central Hospital of Dalian University of Technology were retrospectively analyzed. The Hp infection status was detected by 14C-urea breath test. The relevant clinical data were recorded including age, gender, body mass index (BMI), total cholesterol (TC), triacylglycerol (TG), smoking history, Hp infection status, polyp diameter, polyp number, polyp location and polyp pathological classification. Multivariate Logistic regression was used to analyze the independent risk factors of colorectal polyp. Results:Among the 637 patients, 437 patients suffered from colorectal polyp (colorectal polyp group), and 200 patients had no colorectal polyp (control group). There were no statistical difference in age, TC and smoking history between two groups ( P>0.05); the male proportion, BMI, TG and Hp infection rate in colorectal polyp group were significantly higher than those in control group: 57.44% (251/437) vs. 35.00% (70/200), (24.34 ± 3.24) kg/m 2 vs. (23.70 ± 3.40) kg/m 2, 1.47 (0.93, 1.75) mmol/L vs. 1.31 (0.86, 1.63) mmol/L and 54.46% (238/437) vs. 40.00% (80/200), and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that gender and Hp infection were independent risk factors of colorectal polyp ( OR = 2.260 and 1.545, 95% CI 1.568 to 3.258 and 1.082 to 2.208, P<0.01 or <0.05). Among the 437 patients in the colorectal polyp group, Hp infection was in 238 cases, and non- Hp infection was in 199 cases. There was no statistical difference in polyp location between Hp infection patients and non- Hp infection patients ( P>0.05); the rates of polyp diameter ≥0.5 cm, multiple polyp and adenomatous polyp in Hp infection patients were significantly higher than those in non- Hp infection patients: 66.81% (159/238) vs. 53.27% (106/199), 55.04% (131/238) vs. 36.68% (73/199) and 67.23% (160/238) vs. 54.77% (109/199), and there were statistical differences ( P<0.01). Conclusions:Hp infection is an important pathogenic factor for colorectal polyp. Hp infection is associated with some clinical features of colorectal polyp.
