Endosonography-guided biliary drainage (ESBD), which was first reported in 2001 by Giovannini et al., has recently been performed mainly in cases of biliary obstruction when endoscopic biliary drainage (EBD) is unsuccessful. The technical success rate and complication rate of ESBD have been reported to be 75-100% and 0-50%, respectively. In performing ESBD, due to the short patency periods of plastic stents, self-expandable metallic stents (SEMS) should be used for cases with possible long-term survival as SEMS has longer patency periods. Lack of specialized endoscopic devices to perform ESBD has prevented its widespread use. Although the indications for ESBD have not been established, ESBD, at least, is expected to replace PTBD because of its many advantages over PTBD.
