Figure 1 Kaplan-Meier analysis. A and B: In the stent-laparoscopy (green line) and stent-open (blue line) groups, there were no significant differences in overall survival and disease-free survival (P = 0.915 and P = 0.731); C and D: In the stent-laparoscopy (green line) and control (blue line) groups, there were also no significant differences in overall survival and disease-free survival (P = 0.844 and P = 0.124).
