Clinical utility of treatment method conversion during single-session endoscopic ultrasound-guided biliary drainage

Table 2 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)

¹Technical success was defined as successful stent deployment at the target site.

²Clinical 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.

³In 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.
