ALB and Ascites: Serum albumin (mean: 35.67 ± 3.581 vs. 32.45 ± 4.708, P = 0.004), maximum small bowel dilation diameter (mean: 0.71 ± 0.076 vs. 0.76 ± 0.085, P = 0.047), the ratio of anteroposterior to transverse abdominal diameter (mean: 0.72 ± 0.058 vs. 0.77 ± 0.059, P = 0.017), liver metastases (0.20vs 0.56, P < 0.01), ascites (0.61vs0.30, P < 0.01) were selected as the predictive variables of the nomogram.
