Analysis of Factors Influencing Postoperative Wound Infection in Patients with Pelvic Tumors

Objective: To investigate factors associated with postoperative wound infection in patients undergoing surgery for pelvic tumors, thereby providing a reference for clinical practice and reducing the incidence of wound infection in this population. Methods: Clinical data of 152 patients with pelvic tumors who underwent surgery in the Department of Musculoskeletal Oncology at Sun Yat-sen University Cancer Center from January 1, 2023, to March 1, 2026, were selected for retrospective analysis. Univariate analysis of variance was used to identify risk factors associated with wound infection, and the selected factors were further examined using multivariate logistic regression analysis. Results: Among the 152 patients who underwent pelvic tumor surgery, 28 developed wound infections with positive bacterial cultures, including 11 cases of Gram-positive bacteria, 12 cases of Gram-negative bacteria, and 5 cases of mixed infections. A history of diabetes, low preoperative albumin, and postoperative fecal incontinence were identified as independent risk factors for wound infection after pelvic tumor surgery (P < 0.05). The effects of age, sex, BMI, hypertension, reoperation, and a history of radiotherapy at the surgical site on the occurrence of wound infection were not statistically significant (P > 0.05). Conclusion: When formulating the surgical plan for pelvic tumors and during the postoperative treatment and care of wound infections in patients with pelvic tumors, attention should be paid to these risk factors to reduce the occurrence of wound infections.
