Case 2. The patient had a stenosis of the left hepatic duct after the right hepatectomy (A-1). There were multiple stones upstream of the stenosis (B-1,B-2). The stones were removed by electrohydraulic shockwave lithotripsy under oral cholangioscopy. However, the stenosis was not dilated by the plastic stent (A-2); hence, a self-expandable metallic stent was placed (A-3). One month later, the stent was removed, and cholangiography showed improvement of the stenosis (A-4).
