Figure 4 Comparison of the total cost of hospitalization and operation between the two groups. Dark grey represents the cost using the OrVilTM system (Group I) and light grey represents the cost using the hemi-double stapling technique (HDST) method (Group II). The cost of operation using the OrVilTM system was significantly greater than that of using the HDST method (P < 0.001, Group I vs Group II).
