Comprehensively evaluate the short outcome of small bowel obstruction: A novel medical-economic score system

Figure 1 Workflow of this study. CT: Computed tomography; PC: Principal component; LOS: Length of stay; SAE: Severe adverse event.

Figure 2 Risk factors for worse outcome of small bowel obstruction. Risk estimates for high hospital cost; Risk estimates for severe adverse event; Risk estimates for longer length of stay. OR: Odds ratio; CI: Confidence interval; BMI: Body mass index; WBC: White blood cell; NE%: Neutrophil percentage; NLR: Neutrophil to lymphocyte ratio; LMR: Lymphocyte to monocyte ratio; Hb: Hemoglobin; PLT: Platelet, ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; Ca: Calcium; Cl: Chloride; K: Potassiun; Na: Sodium; BUN: Blood urea nitrogen; Glu: Glucose; PT: Prothrombin time; APTT: Activated partial thromboplastin time; DDI: D-dimer; Fib: Fibrinogen; SAE: Severe adverse event; LOS: Length of stay.

Figure 3 Receiver operating characteristic curve for high principal component score prediction. The areas under the curve were 0.715 (95%CI: 0.635-0.795), 0.874 (95%CI: 0.762-0.986), respectively. A: Receiver operating characteristic curve of simple small bowel obstruction group for high principal component score prediction. B: Receiver operating characteristic curve of strangulated small bowel obstruction group for high principal component score prediction. ROC: Receiver operating characteristic.
