A 64-year-old man who had undergone subtotal stomach-preserving pancreaticoduodenectomy with modified Child’s reconstruction for ampullary carcinoma presented with fever and jaundice. Blood tests showed cholangitis, and magnetic resonance imaging revealed multiple intrahepatic bile duct stones (IBDSs) ([Fig. 1]). Therefore, endoscopic treatment was planned. A forward-viewing endoscope (PCF-H290TI; Olympus Medical Systems, Tokyo, Japan) was inserted. The choledochojejunal anastomotic site had a pinhole-like opening ([Fig. 2]). Endoscopic retrograde cholangiography (ERC) revealed multiple large IBDSs ([Fig. 3], [Fig. 4]). Based on these findings, multiple large IBDSs with benign choledochojejunal anastomotic stenosis were diagnosed. The strategy of endoscopic treatment was to first dilate the anastomotic site with the placement of a temporary fully-covered self-expandable metal stent (FCSEMS) and remove the stones. The choledochojejunal anastomotic site was dilated by a balloon dilator followed by the placement of two plastic stents and then FCSEMS ([Fig. 5]). These stents were removed endoscopically after 2 months, and stricture resolution of the choledochojejunal anastomotic site was achieved. IBDSs were observed by peroral direct cholangioscopy (PDCS) using a forward-viewing endoscope (SIF-H290S; Olympus Medical Systems). Electrohydraulic lithotripsy (EHL) for the right IBDSs and crushed stone extraction by a basket under PDCS were performed; however, the left IBDSs remained. One month later, balloon dilatation was performed at the choledochojejunal anastomotic site because it was narrower; similar procedures were performed on the remaining IBDSs, and PDCS and ERC revealed no IBDS residue ([Video 1]).

Quality:

The endoscopic treatment of IBDSs with benign choledochojejunal anastomotic stenosis is extremely difficult. The usefulness of placing a FCSEMS for benign biliary strictures including benign choledochojejunal anastomotic stenosis has been demonstrated [1] [2] [3]. However, few studies have reported the utility of combining FCSEMS placement and EHL under cholangioscopy for bile duct stones with intrahepatic benign biliary strictures and such strictures of the common bile duct as well as the surgically altered anatomy [4] [5]. These combined techniques may be useful for complex IBDSs with benign choledochojejunal anastomotic stenosis.
