Background: Results of endoscopic ultrasound-guided biliary drainage (EUBD) are unknown in case of proximal stricture. The aim is to assess clinical outcomes of EUBD in patients with malignant hilar obstruction. Methods: Patients undergoing EUBD with hilar strictures were prospectively included. Primary outcome was clinical success at 7 and 30 days (defined by 50% bilirubin decrease). Secondary outcomes were technical success, procedure-related complications, length of hospital stay, reintervention rate, survival and chemotherapy administration. Results: Eighteen patients with a mean age of 68.8 years were included. On 15 classable stenosis, 7 (47%) were noted Bismuth I–II, 7 (47%) Bismuth III, and 1 (6.7%) Bismuth IV. Reasons for EUBD were surgically modified anatomy in 10 patients (55.6%), impassable stricture at ERCP in 7 (38.9%) and duodenal obstruction in 1 (5.6%). Only hepaticogastrostomy was performed. Clinical success was at day 7 and 30 respectively 72.2% and 68.8%. Technical success was 94%. Complications occurred in 3 (16.7%) patients. Median (range) length of hospital stay was 10 (6–35) days. Reintervention rate was 16.7%. Median (range) survival was 79 (5–390) days. Chemotherapy was possible in 10 (55.6%) patients. Conclusions: EUBD is feasible for hilar obstruction for surgically altered anatomy or after ERCP failure. Clinical outcome is satisfactory when considering underlying advanced disease, allowing chemotherapy.
