Clinical outcomes of patients who underwent treatment method conversion from initially planned endoscopic ultrasound-guided biliary drainage
| Patient characteristics | n = 39 |
| 1Technical success, n (%) | 383 (97.4) |
| Median procedural time (range, min) | 65 (26-115) |
| 2Clinical success, n (%) | 34 (89.5) |
| Adverse events (%) | 4 (10.3) |
| Bile leakage | 2 (5.1) |
| Bleeding | 1 (2.6) |
| Cholecystitis | 1 (2.6) |
1
Technical success was defined as successful stent deployment at the target site.
2
Clinical success was defined as the improvement of cholangitis or a decrease in serum bilirubin levels to normal or by ≥ 50% within 2 wk following endoscopic ultrasound-guided biliary drainage.
3
In one patient, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) was unsuccessful due to failed guidewire manipulation, and alternative EUS-HGS via another biliary branch was also unsuccessful due to the difficulty in puncture. In this case, percutaneous drainage was successfully performed instead.
