Figure 1 Kaplan-Meier estimation of cumulative patency rates of biliary drainage according to the procedures in all Bismuth types (P = 0. 02 for ERBD vs IPTBD, P < 0.01 for ERBD vs EPTBD, P < 0.01 for IPTBD vs EPTBD). ERBD: endoscopic retrograde biliary drainage; EPTBD: external percutaneous transhepatic biliary drainage; IPTBD: internal biliary stenting via PTBD tract.

Figure 3 Kaplan-Meier estimation of cumulative patency rates for biliary drainage according to the procedures in patients with Bismuth type II Klatskin's tumor (P > 0. 05 between drainage procedures ). ERBD: endoscopic retrograde biliary drainage; EPTBD: external percutaneous transhepatic biliary drainage; IPTBD: internal biliary stenting via PTBD tract.

Figure 4 Comparison of cumulative patency rates for biliary drainage according to the procedures in patients with Bismuth type III (P = 0. 23 for ERBD vs IPTBD; P < 0.01 for ERBD vs EPTBD; P < 0.01 for IPTBD vs EPTBD). ERBD: endoscopic retrograde biliary drainage; EPTBD: external percutaneous transhepatic biliary drainage; IPTBD: internal biliary stenting via PTBD tract.

ERBD: endoscopic retrograde biliary drainage; EPTBD: external percutaneous transhepatic biliary drainage; IPTBD: internal biliary stenting via PTBD tract.
