[Neuropsychological Risk Factors for Chronic Postoperative Pain Following Abdominal Surgery].

Objective: To analyze the incidence of chronic postoperative pain (CPSP) after patients have undergone abdominal surgery and identify the neuropsychological risk factors involved. Methods: A total of 102 patients who underwent abdominal surgery at our hospital between January 2023 and January 2025 were enrolled. The general demographic and surgery-related data were collected. Three months after surgery, follow-up assessments were conducted via outpatient visits or telephone interviews. The occurrence of CPSP was assessed using the Numerical Rating Scale (NRS). Neuropsychological status was evaluated using the Mini-Mental State Examination (MMSE), the Self-Rating Anxiety Scale (SAS), the Self-Rating Depression Scale (SDS), and the Pain Catastrophizing Scale (PCS). Univariate and multivariate logistic regression analyses were performed to identify independent influencing factors associated with CPSP. Results: Among the 102 patients, the incidence of CPSP at 3 months post-surgery was 31.37% (32 cases). Significant differences were observed between the CPSP and non-CPSP groups with respect to age, duration of surgery, postoperative length-of-stay in the hospital, SDS scores, and PCS scores ( Conclusion: Age and PCS are risk factors for CPSP in patients undergoing abdominal surgery, while the length of postoperative length-of-stay is a protective factor. Targeted strategies, including preoperative screening, psychological interventions, and optimized pain management for high-risk patients are recommended to reduce the incidence of CPSP.
