Interventional endoscopic ultrasonography (EUS) based on EUS-guided fine-needle aspiration has rapidly spread as a minimally invasive procedure. Especially in patients with failed endoscopic retrograde cholangiopancreatography, EUS-guided biliary intervention is reported to be useful as salvage therapy. EUS-guided biliary interventions are carried out using three techniques: EUS-guided bilioenteric anastomosis, EUS-guided rendezvous procedure, and EUS-guided antegrade treatment. Although interventional EUS is not yet a standardized procedure, there have been recent advances in this field that address various biliary diseases. Here, we summarize the indications, techniques, clinical results of previous studies, and future perspectives.
Core tip: Endoscopic-ultrasonography-guided biliary drainage (EUS-BD) is widely accepted as salvage therapy for transpapillary treatment. However, there are few data comparing the clinical efficacy of EUS-BD and endoscopic retrograde cholangiopancreatography (ERCP) with regard to which is the treatment of choice. As EUS-BD is performed under direct visualization, it has the potential to replace ERCP. However, a prospective randomized study is necessary to confirm it.
