EUS-guided hepaticoenterostomy (EUS-HE) usually is reserved for palliation of malignant biliary obstruction after failed endoscopic retrograde cholangiography (ERC) or inaccessible biliary tree in surgically altered anatomy (SAA). We describe the outcome of EUS-HE and antegrade therapy for benign biliary disease in patients with SAA.Retrospective review of 20 consecutive patients with surgically altered anatomy and benign biliary obstruction who underwent EUS-HE performed by 1 endoscopist at a tertiary-care center over a 3-year period.During the study period, 37 patients underwent EUS-HE; 24 for benign disease. Of these, 20 patients had SAA and were analyzed (15 women, mean age, 62 years). SAA consisted of 9 Roux-en-Y gastric bypasses, 6 Roux-en-Y hepaticojejunostomy, 2 Billroth II procedures, and 3 Whipple procedures. Indications for ERC were common bile duct stones (n = 8), benign postoperative strictures (n = 7), chronic pancreatitis (n = 3), inflammatory stricture (n = 1), and treatment of a bile leak (n = 1). Five patients had previously failed balloon enteroscopy-assisted ERCs. The approach was transgastric in 15 and transjejunal in 5. In all cases, a branch of the left hepatic duct with a mean diameter of 7.8 mm was accessed. Median stent length was 80 mm, with diameters of 8 or 10 mm. Antegrade, definitive endoscopic therapy via the HE was performed in 18 patients, with an average of 2.7 procedures performed for resolution of stones and/or downstream strictures. HE stents were removed in 17 patients after a mean of 91 days without adverse events. Three patients experienced mild adverse events (1 with postprocedural pancreatitis after placement of a 10F transpapillary stent, 1 with postprocedural abdominal pain, and 1 with postprocedural cholangitis) requiring hospitalization for fewer than 3 nights; no severe adverse events occurred. The average postprocedural hospital stay was 1.3 days. No deaths occurred during follow-up.EUS-HE is safe and effective in the management of benign biliary obstruction in patients with surgically altered anatomy. It creates a portal to allow definitive, antegrade therapy and is a viable alternative to other endoscopic methods in this patient population.
