Figure 2 Kaplan-Meier curves for all biliary interventions according to the anastomosis site angle1. The Kaplan-Meier curves show that group 1 had a significant survival advantage without biliary intervention compared with group 2 (62.0% vs 36.3%, P < 0.001). 1The groups were categorized according to the anastomosis site angle (median angle = 113.3°); group 1, angle > 113.3°; group 2, angle ≤ 113.3°.
