Abstract
Abstract Various factors contribute to different types of surgical site infections (SSI) in gastric cancer patients undergoing surgery, and the risk factors remain uncertain. This meta‐analysis aims to clarify the relationship between various factors and SSI, resolving existing controversies. Thirty‐four eligible articles with 66 066 patients were included in the meta‐analysis. Significant risk factors for SSI included age ≥65 years, male gender, BMI ≥25 kg/m 2 , diabetes, hypertension, advanced TNM stage ≥III, pathologic T stage ≥T3, pathologic N stage ≥N1, ASA ≥3, open surgery, blood transfusion, extensive resection, combined resection, splenectomy, D2 or more lymph node dissection, and operative time ≥240 min. Operative time showed a nonlinear relationship with SSI risk. Subgroup analysis revealed significant differences in the effects of risk factors among different infection types. These findings inform the development of targeted preventive measures to reduce SSI rates.
