Table 3.

Comparison of the technical success of the percutaneous procedures between percutaneous-endoscopic rendezvous procedures (PTE-RVs) and percutaneous transhepatic cholangiographies (PTCs). Percentages are reported for categorical variables. The technical success of PTC was defined as the establishment of percutaneous access to the biliary tract allowing a subsequent intervention for biliary drainage. The technical success of PTE-RVs was defined as the establishment of intestinal access to the biliary tract allowing a subsequent intervention using a percutaneous-endoscopic rendezvous procedure. Statistical differences were calculated using a one-tailed Fisher exact test.

Variables	Overall	PTE-RV	PTC	p value
Technical success (%)	481/553 (87.0)	131/163 (80.4)	350/390 (89.7)	p < 0.003 a
Technical failure (%)	72/553 (13.0)	32/163 (19.6)	40/390 (10.3)

Two-sided p values < 0.05 were considered statistically significant.
