  Fig. 1. Receiver operating characteristic curves for intraoperative in–out balance per body weight. The area under the curve (AUC) was 0.66 (95% confidence interval [CI], 0.57–0.75), and the cutoff value was 46.3 ml/kg (sensitivity: 0.47, specificity: 0.86)

  Fig. 2. Number of matched independent factors and the incidence of postoperative ileus. The independent factors included are poor performance status (0 or 1) and intraoperative in–out balance per body weight. The incidence of anastomotic leakage is 2.5% when all factors are absent; however, it increases to 36.1% with two factors and to 75.0% with three factors
