Abstract
Common bile duct (CBD) stones may cause septic shock and lead to life-threatening conditions [1]. Endoscopic sphincterotomy (EST) and stone removal is an accepted method for the treatment of CBD stones [2]. EST has the potential to cause bleeding in patients with a bleeding risk. However, endoscopic retrograde biliary drainage (ERBD) can be performed effectively and safely without EST in these patients. ERBD has been performed under fluoroscopy, resulting in a relatively long duration of radiation exposure [3] [4]. Intraductal ultrasound (IDUS) provides real-time cross-sectional imaging within the bile duct. IDUS can be performed without fluoroscopy. Therefore, IDUS-directed ERBD can be used to reduce the time of radiation exposure for both examiners and patients. This report describes IDUS-directed ERBD with a plastic stent without fluoroscopy in patients with a risk of bleeding.
