Successful Drainage Rates and Comparison of Drainage Failure Rates
| Rate | Initial EBD, OR (95% CI) | Overall EBD, OR (95% CI) | |||
|---|---|---|---|---|---|
| BMS | MPS | BMS | MPS | ||
| Successful drainage, % (No./total No.) | 71.4 (25/35) | 65.6 (44/67) | |||
| Drainage failure | |||||
| Crude | Reference | 1.31 (0.54–3.18) | Reference | 1.03 (0.59–1.81) | |
| Adjusted | Reference | 1.17 (0.44–3.14) | Reference | 1.08 (0.59–1.67) | |
Adjusted for body mass index, bismuth type (I/II, IIIa/IIIb and IV), time varying total bilirubin, PT INR, and albumin.
EBD, endoscopic biliary drainage; OR, odds ratio; CI, confidence interval; BMS, bilateral metal stents; MPS, multiple plastic stents; PT, prothrombin time; INR, international normalized ratio.
