Table 4.
Comparison of adverse events associated with the percutaneous procedures between percutaneous-endoscopic rendezvous procedures (PTE-RVs) and percutaneous transhepatic cholangiographies (PTCs). Percentages are reported for categorical variables. The overall complication rate combining complications related to the procedure and biliary drainage complications within one month after the intervention.
| Variables | Overall (n = 553) | PTE-RVs (n = 163) | PTCs (n = 390) | p value |
|---|---|---|---|---|
| Overall complication rate | 130 (23.5) | 27 (16.6) | 103 (26.4) | 0.037 a |
| Procedure-related complications (% per procedure) | 71 (12.8) | 14 (8.6) | 57 (14.6) | 0.069 |

| Liver biloma | 3 (0.5) | 0 (0.0) | 3 (0.8) | |
| Others | 4 (0.7) | 1 (0.6) | 3 (0.8) | |
| Drainage-related complications (% per procedure) | 59 (10.7) | 13 (8.0) | 46 (11.8) | 0.227 |

| > 1 week and ≤ 1 month | 15 (2.7) | 2 (1.2) | 13 (3.3) |
Two-sided p values < 0.05 were considered statistically significant.
