Anchor-wire technique for multiple plastic biliary stents to prevent stent dislocation

Figure 1 The first endoscopic retrograde cholangiography showed severe biliary stenosis with type III hilar biliary stricture according to Bismuth’s classification.

Figure 2 The second endoscopic retrograde cholangiography: the guidewire going through the side hole of the first plastic biliary stent worked as anchor-wire.

Figure 3 The endoscopic image at the third endoscopic retrograde cholangiography: the anchor-wire was inserted through the side hole of the first plastic biliary stent towards the duodenal bulb and another guidewire beside the plastic biliary stent.
