The Use of Oblique-viewing Endoscopic Ultrasound for Accessing the Afferent Limb for Endoscopic Ultrasound-guided Biliary Drainage in Patients with Severe Stenotic Hepaticojejunal Anastomosis: One Case and Literature Review.

Background: The treatment of hepaticojejunal anastomotic strictures in patients with surgically altered anastomosis is challenging. Endoscopic ultrasound (EUS)-guided biliary drainage is being established as a feasible biliary drainage procedure. How can oblique-viewing endoscopic ultrasound (OV-EUS) safely reach the treatment area in the afferent limb for EUS-guided hepaticojejunostomy? This is a key, meaningful, and challenging question.
