Figure 1 . The distribution of the maximal CT value In the Simple group [A], the minimum CT value was 0, the maximum was 790, and the average was 94.7 ± 171.5 In the Manipulation group [B], the minimum CT value was 166, the maximum was 1304, the average was 638.1 ± 269.5.
Figure 2. Receiver operating characteristic curve analysis and area under the curve calculated for manipulation. The maximal CT value enabled us to predict the simple anastomosis with the AUC (area under the receiver operating characteristic curve) of 0.96 (p<0.0001). The cutoff value for the maximal CT value to predict manipulation was 325 HU (sensitivity 94.1%, specificity 81.7%).
Figure 3A . Postoperative 10-year acutual survival rate shows by the Kaplan-Meier curve. The 5-year and 10-year survival rate were 69.7% and 38.3% in all patients.
Figure 3B. The 5-year and 10-year survival rate were 73.3% and 43.2% in the Simple group and 47.6% and 11.2% in the Manipulation group.
