Percutaneous transhepatic biliary drainage frequently remains the treatment of choice when the transpapillary approach proves ineffective. Recently, EUS-guided extra-anatomical anastomoses of bile ducts to the gastrointestinal tract have been reported as an alternative to percutaneous biliary drainage. To assess the usefulness of extra-anatomical intrahepatic biliary duct anastomoses to the gastrointestinal tract as endotherapy for unresectable malignant biliary obstruction and to determine factors affecting the efficacy of treatment.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A prospective analysis of the treatment results of all patients with unresectable biliary obstruction treated with EUS-guided hepaticogastrostomy at our institution in the years 2016\u20132019.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Transmural intrahepatic biliary drainage (EUS-guided hepaticogastrostomy) was performed due to the ineffectiveness of ERCP in 53 patients (38 males, 15 females; mean age 74.66 [56\u201389] years) with unresectable biliary obstruction. Technical success of EUS-guided hepaticogastrostomy was achieved in 52\/53 (98.11%) patients. Complications of endoscopic treatment were observed in 10\/53 (18.87%) patients.
