Abstract: OBJECTIVE: To investigate the risk factors for preoperative bowel dysfunction in patients with acute Stanford Type B aortic dissection. METHODS: A retrospective analysis was conducted on 184 patients diagnosed with Stanford Type B aortic dissection between January 2023 and December 2024. These patients were divided into two groups: the bowel dysfunction group (n = 49) and the non-bowel dysfunction group (n = 135). Baseline characteristics, echocardiographic findings, myocardial enzyme levels, dietary habits, and psychological status were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors. A nomogram was developed to facilitate clinical prediction. RESULTS: Preoperative constipation was observed in 26.63% (49/184) of patients. Logistic regression analysis identified older age, higher Self-Rating Depression Scale (SDS) score and Self-Rating Anxiety Scale (SAS) score as independent risk factors for preoperative bowel dysfunction. Conversely, higher intake of fruits, vegetables, and water was associated with a reduced risk. The nomogram demonstrated good predictive performance, with an AUC of 0.930 in the training cohort and 0.884 in the validation cohort. CONCLUSIONS: Preoperative bowel dysfunction is common among patients with acute Stanford Type B aortic dissection. Age, dietary habits, and psychological status are significant risk factors. Close monitoring and targeted management of these factors may help reduce the incidence of preoperative bowel dysfunction.
