Objective To comprehensively evaluate the incidence of venous thromboembolism (VTE) after colorectal surgery.Methods We searched PubMed/Medline, Web of science, and Embase databases by computer, collected studies by using the combination of corresponding English keywords. Then, we screened literatures according to inclusion and exclusion criteria, and evaluated the quality of literatures by using Downs and Black tools. Finally, we used Stata 15.1 and R Project 3.4.1 for meta-analysis.Results A total of 15 studies (n=721 730) were included in the meta-analysis. The combined incidence of VTE after colorectal surgery was 2.26% [95% CI was (1.93%, 2.61%), P<0.000 1], and the incidence of VTE after adjusting for publication bias was 1.82% [95% CI was (1.53%, 2.13%), P<0.000 1]. Meta regression analysis revealed that patients’ age (P<0.000 1), smoking (P=0.000 4), open surgery (P=0.020 0), preoperative albumin level (P=0.023 6), and malignant tumor (P=0.036 4) were correlated with the incidence of VTE after colorectal surgery, which may be potential factors for heterogeneity.Conclusions The incidence of VTE after colorectal surgery is not insignificant. It is necessary for clinicians to be vigilant about the occurrence of VTE after colorectal surgery and provide appropriate preventive interventions in combination with patients’ own risk factors, disease-related factors, and surgical factors.
