EUS-guided hepaticogastrostomy (EUS-HGS) is performed for benign biliary diseases as an alternative therapy for ERCP. However, a critical adverse event such as stent migration was reported.[1] Recently, stent retrieval method in the HGS route using Spy bite (Boston Scientific, Marlborough, Massachusetts, USA),[2] forceps,[3] or balloon[4] has been reported. We report a case that the plastic stent (PS) retrieval method using Spy basket (Boston Scientific) [Figure 1] and grasping the flap of PS was efficient as a new stent retrieval method.

A 70-year-old man with a history of pancreaticoduodenectomy was admitted to our institution to treat intrahepatic biliary stones. Because we failed to remove stones under enteroscope-assisted ERCP due to the instability of the scope, we decided to perform EUS-HGS. At first, a PS was placed in the choledochojejunostomy route, and a metallic stent was placed across the HGS route due to the incomplete stone extraction because of large stone size [Video 1 [Additional file 1]]. One month later, the PS was revealed to be placed into B2 [Figure 2]a. It seemed to be difficult to retrieve the PS because of embedding into not B3 but B2. After we removed the metallic stent in the HGS route, cholangioscope (Spy-Glass DS; Boston Scientific) was inserted. Although we failed to catch the PS by Spy bite under direct visualization [Video 2 [Additional file 2]], we could successfully grasp the flap of embedded stent and easily retrieve it using a Spy basket [[Figure 2]b, [Figure 2]c and Video 3 [Additional file 3]]. Finally, stones were completely extracted using electrohydraulic lithotripsy with a cholangioscopy. No procedure-related adverse events occurred [Figure 2]d. Although stent dislocation can be a serious complication during interventional EUS and may need surgical intervention, cholangioscopy-guided grasping the flap of PS by Spy basket can be an effective method for retrieval of embedded PS.
