摘要
Background To develop and validate a risk score for predicting clinical success after duodenal stenting using self-expanding metallic stents (SEMS) for malignant gastric outlet obstruction (GOO). Research design and methods Consecutive patients who underwent duodenal stenting for malignant GOO were evaluated. Potential predictors of clinical success were determined by uni/multivariate logistic regression analysis. Multiplication of the regression coefficients of the logistic regression model by a factor of two and rounding to obtain easy-to-use point numbers enabling the calculation of the score. Using 10-fold cross-validation, the model was internally validated. Results One hundred twelve patients were included. Clinical success was achieved in 93 (83.0%) patients. On multivariate logistic regression, selected age <= 65 years (p = 0.05, 1.5 points), stenosis type I (p = 0.04, 3 points), and pancreatic cancer (p = 0.01, 3.5 points) were significant predictors of clinical success. On the Receiver Operating Characteristic (ROC) analysis, a score of 5 had higher specificity and sensitivity. Conclusion Our score could be useful at identifying, among poor surgical candidates, patients more likely to benefit from SEMS.
