Background: Despite the increasing use of EUS-BD, the inferiority of PTBD versus EUS-BD in patients with unresectable MDBO after failed ERCP has not been demonstrated in a prospective, multicenter, international study.

Methods: In 14 centers in Spain and Germany, patients were assigned to the center with the highest competence for PTBD or EUS-BD. Primary metal stenting was planned in both groups. The primary endpoint was technical success. The study was designed as a non-inferiority trial with a 6-month follow-up period and propensity score matching.

Results: A total of 209 patients (mean age 73 years) were included in the study between 12/2018 and 8/2024. PTBD was technically successful in 62/68 (91.2%) and EUS-BD in 138/141 (97.9%) of patients (p=0.06), including 58 hepatogastrostomies, 58 choledochoduodenostomies, 17 anterograde stents and 5 rendezvous procedures with ERCP. Pancreatic and gastric cancer were the leading causes of MDBO (77%) and gastric outlet obstruction was the leading cause of failed ERCP (49%). Clinical success (≥50% bilirubin reduction/7d), pain score, rate of adverse events (grade 1-4), length of hospital stay and overall survival were not significantly different, except for procedure time (43.7 vs. 58.1 minutes) and rate of biliary re-interventions per patient within 30 days (0.04 vs. 0.31/patient) in favor of EUS-BD.

Conclusions: Despite a trend in favor of EUS-BD, PTBD with primary metal stenting was not inferior for unresectable MDBO except for procedure time and rate of biliary re-interventions. Depending on the expertise of the center, both procedures may still be a possible treatment option after failed ERCP. (ClinicalTrials.gov number NCT03546049).
