Endoscopic ultrasound-guided biliary recanalization with a novel rendezvous inflated balloon-assisted technique for isolated bile leakage

Bile leakage after hepatectomy has been reported to occur in 5 %–8 % of cases 1 2. In particular, isolated bile leakage is intractable and may require surgical re-anastomosis. In general, endoscopic treatment for isolated bile leakage by transpapillary biliary drainage for recanalization is challenging 3; the procedure is often unsuccessful because of surgically altered anatomy and disconnection of the bile duct. Here, we report a case of successful endoscopic ultrasound (EUS)-guided biliary recanalization for isolated bile leakage that employed a novel approach assisted by rendezvous balloon inflation.
