Abstract:   (1308 Views)
Background: To analyze the value of quantitative parameters of Computed Tomograph (CT) abdominal fat in predicting postoperative intestinal obstruction for gastric cancer. Materials and Methods: A retrospective analysis was conducted on 120 gastric cancer patients treated between January 2017 and December 2021. These patients were divided into two groups: an observation group with postoperative intestinal obstruction (28 patients) and a control group without (92 patients). CT scans were used to measure the Subcutaneous Fat Area (SFA) and Visceral Fat Area(VFA), calculate the SFA-VFA difference, and the VFA/SFA ratio. The receiver operating curve (ROC) was employed to evaluate the predictive efficacy of these CT measurements. Results: The observation group exhibited significantly lower VFA and SFA compared to the control group (P < 0.05), while the differences in VFA/SFA ratio and SFA-VFA were not statistically significant. The area under the ROC curve (AUC) for the combined VFA and SFA in predicting postoperative intestinal obstruction was 0.902, with a 95% confidence interval of 0.859 to 0.956. This combined measure showed higher sensitivity (96.02%) and comparable specificity (85.24%) than single measurements. Logistic regression analysis identified diabetes, malnutrition, C-Reactive Protein (CRP) levels, VFA, and SFA as risk factors for postoperative intestinal obstruction (P < 0.05). Conclusion: The combined quantitative assessment of VFA and SFA using abdominal CT improves the sensitivity of predicting postoperative intestinal obstruction in gastric cancer patients. This complication is multifactorial, emphasizing the importance of a comprehensive approach in the clinical evaluation and management of these patients.
